Give Thanks with Pumpkin Fudge

Skip the pie—bring pumpkin fudge and get invited back next year!

Julie McCaffrey —  November 21, 2014 — Leave a comment

No Thanksgiving is complete without a pumpkin dish—and it doesn’t hurt to spice it up with a little something extra…

If you’re ready to start a new tradition (enough already with the pumpkin pie, pumpkin bread, and pumpkin cookies), consider chef Michael Kingsley’s bourbon pumpkin-pecan fudge (available now at the Garden View Café). The bourbon gives the fudge a bit of a kick (and who doesn’t need a little jump-start during the holidays?).

The recipe is simple enough to get the whole family involved. Think butter…pumpkin…toasted pecans—what’s not to like? And what better way to celebrate the season than to spend time together, break fudge together, and give thanks that you’re able to do so?

Pull out your candy thermometer, 4-quart sauce pan, wooden spoon, measuring cups and spoons, 13-by-9-inch pan, aluminum foil, nonstick cooking spray, and seasonal cookie cutters (and get the camera ready—not that anyone is going to lick the spoon…). This is going to be delicious.

Bourbon Pumpkin-Pecan Fudge

1¾ cups sugar
1¼ cups brown sugar
¾ cup unsalted butter
2/3 cup evaporated milk (5-ounce can)
½ cup canned pumpkin purée (no added sugar) 
2 teaspoons cinnamon
1 teaspoon ginger
¼ teaspoon nutmeg
¼ teaspoon allspice
2¼ cups white chocolate chips
7 ounces marshmallow fluff (any brand)
1 teaspoon salt
1 teaspoon bourbon (optional, but worth it!)
1 teaspoon vanilla extract
1 cup pecans, toasted and chopped

Start by covering a 13-by-9-inch pan with aluminum foil. Spray the covered pan with cooking spray. Sprinkle the chopped pecans evenly over the bottom of the pan. (They do not have to completely cover it.) Set aside.

Combine the sugar, brown sugar, butter, evaporated milk, pumpkin purée, spices, and salt in a pan. Bring to a boil over medium heat and continue to boil until the temperature reaches 236 degrees Fahrenheit on your candy thermometer. Remove from heat.

Working quickly, add the white chocolate chips, marshmallow fluff, bourbon, and vanilla to the pan. Be careful, as this may spatter and will be very hot! Fold ingredients in until completely incorporated. Pour the hot fudge mixture over the chopped pecans and quickly spread evenly; it will immediately start to set up as it cools.

Place the pan uncovered in the refrigerator for at least 3 hours. Your mouth is probably watering already, but unfortunately, it will take this long to set up completely.

After cooling the pan completely for 3 hours, remove the pan from the refrigerator, and turn it upside down on a cutting board. The fudge should pop right out. Peel off the aluminum foil and discard. Want to make your treats extra special? Use cookie cutters to cut your fudge into festive autumn shapes—or maybe dinosaurs if you’re that kind of person—and enjoy!

Note: If you have it in your spice rack, you can substitute 3½ teaspoons of “pumpkin pie spice” for the cinnamon, nutmeg, ginger, and allspice.

Checking the Weather? So Are We.

It's how you connect to the Garden every day.

Karen Z. —  November 17, 2014 — 2 Comments

It’s the humblest patch of green at the Garden, yet the information gathered there has national implications—and, though you may not realize it, it’s part of your daily prep for work, school, and play.

Although dealing with the weather is part of everyone’s job here, there is no meteorologist on staff at the Garden. Got questions about weather specifics or cooperative weather stations?

In a small, sunny, grassy, flat, fenced-in plot (there’s a reason for that), located on the outer road that encircles the Garden, stands an official National Weather Service Cooperative Station—a collection of instruments that measures the atmospheric conditions of the day. And every morning at 8 a.m., rain (or snow) or shine, a dedicated Garden staff member steps into the plot to read the instruments and record the results, then heads back indoors to transfer the information to the National Weather Service (NWS).

I got to tag along with Celeste VanderMey, Plant Records supervisor, on a recent fall morning for the daily readings.

Celeste VanderMey explains that its beehive appearance might deter curious critters from poking around inside the weather shelter.

Reading #1: Temperature

Though it looks vaguely like a beehive, the little white structure is a weather shelter that houses two temperature gauges. The maximum temperature thermometer’s mercury rises to the high temperature mark of each day, then stays at the setting until it’s read the next morning. To reset it, Celeste just gives it a spin and the mercury drops.

An alcohol thermometer records the low temperature of each day: pure alcohol molecules move closer together as the temperature drops, shifting a tiny bar that marks the number.

Why no digital thermometers? “Not considered as reliably accurate,” Celeste says.

A long metal cylinder like a tiny rocket ship turns out to be a rain gauge. Celeste removes the lid and takes a reading.

Reading #2: Dew

Admittedly the least scientific of the daily measurements, dewfall is indicated as low, moderate, or heavy, simply by examining a surface: the top of the weather shelter, or the grass itself.

Reading #3: Rain

The National Weather Service provided us with the rain canister, which can hold up to 10 inches of precipitation (not that we’ve ever had that amount—see records below). Inside is a plastic funnel that directs rainwater into a smaller brass tin. A measuring stick—like a car’s oil dipstick—is inserted, then pulled out and read for rain depth—one-tenth inch of rain equals one inch on the stick.

Reading #4: Soil Temperature

A soil thermometer is as handy for home gardeners as it is for us—especially in spring, when it tells gardeners if it’s warm enough to put seeds in the ground. We measure the high and low temperatures of both bare soil and soil under sod/grass (that’s why the plot is flat, sunny, and grassy). An interesting fact: no matter what the air temperature in winter, the soil seldom drops below 26 degrees (it’s measured at 4-inch depth). 

PHOTO: Weather station soil temperature gauge.

This gauge takes a reading of bare soil temperatures. Five feet over, another gauge measures the temperature under grass. It’s important information for farmers germinating seed.

Reading #5: Snowfall

It’s low tech, but it works: a white plastic board catches a winter day’s snowfall, which is measured with a yardstick to the tenth of an inch. Two or more inches of snow? Then a core sampling is taken down to the ground, and the core is brought indoors to melt for a water equivalency reading. As mentioned below, the NWS uses this information to predict flooding.

Reading #6: Evaporation

Next we moved to the 4-foot in diameter evaporation pan. Its three readings tell forecasters how much water has been absorbed into the atmosphere at this location.

An instrument with an intriguing name, a six’s thermometer, measures both high and low daily temperature of the water in the pan. An anemometer (wind meter) tells how many miles’ worth of wind has passed this spot. And a hook gauge in a stilling well measures the amount of water lost to evaporation (or added by rain).

PHOTO: An anemometer measures wind speed.

The anemometer attached to the evaporation pan measures the wind speed at an exact height. All weather station gear must meet siting requirements, so that data are measured consistently from station to station.

PHOTO: The hook gauge which usually rests in a container inside the evaporation pan.

The hook gauge rests in a standard-size stilling well inside the evaporation pan—the structure the anemometer is attached to in the previous photo.

Reading #7: River and Lake Levels

Finally, we take a short walk across the road to the South Bridge, and the weir (dam) beneath, where the waters of the Garden Lakes meet the Skokie River. Along the banks on each side of the bridge are measurement markers that are read (bring the binoculars!) and recorded daily, although they’re for the Garden’s own record keeping rather than the NWS.

Why track the lake and river levels? Flooding is always a threat in our lake system, says Bob Kirschner, director of Restoration Ecology. “We look at the levels every day,” he explains, “and we can adjust the lake level in anticipation of excessively wet or dry weather forecasts.” All of the Garden’s property is irrigated with water drawn from our lakes. Water levels matter to the half-million lakeshore plants that line the lakes, too—all installed with our normal lake level (623.95 feet above mean sea level) in mind.

Fall in the Great Basin

It takes just a few minutes’ time to record the morning’s numbers. Indoors, Celeste logs on to the NWS site and inputs the results, adding noteworthy conditions as needed: fog…haze…ice…thunderstorms.

Staff has been keeping records since 1982. That’s the year that then-Garden president Dr. Roy Mecklenburg, who was keenly interested in meteorology, arranged for the Garden to become a weather station. Stations existed at the time at Midway Airport and in Antioch, with none in between. A few notable numbers since then (again, note that all are since 1982, when our record keeping began):

  • January 2014 holds our record for snowiest January with 28.7 inches (1967 snowfall was higher).
  • February 2014 holds the record for coldest February: 26.6 degrees average high, usually 35.6 degrees.
  • 1993 holds the record for shortest growing season (number of days between last frost and first frost) at only 123 days. The average? 163 days.
  • August 14, 1987, holds the record for most rainfall in one day: 5.54 inches.

It’s fascinating to think that the Garden contributes daily to the national weather picture and that there’s always an eye on the weather here (thanks to Celeste, Veronica, Gabriella, Therese, and Lauren). Next time you check on the weather and hear a forecaster say, “and the Chicago Botanic Garden reported “x” inches of rain yesterday,” you’ll know where the information came from: a humble patch of green.

A Bit of Weather-Station History

Although it dates back to 1989, the preface of the official National Weather Service Observing Handbook (No. 2) is so wonderfully interesting that it’s blog-worthy on its own. Here’s the text, from page ii, with thanks to the unknown writer:

John Companius Holm’s weather records, taken without the benefit of instruments in 1644 and 1645, were the earliest known observations in the United States. Subsequently such famous personages as George Washington, Thomas Jefferson, and Benjamin Franklin maintained weather records spanning many years.

The first extensive network of cooperative stations was set up in the 1890s as the result of an act of Congress in 1890 that established the Weather Bureau. Today, there are over 11,000 volunteer cooperative observers scattered over the 50 states, taking observations seven days a week throughout the year.

The above observers regularly and conscientiously contribute their time so that their observations can provide the vital information needed to define the climate in their areas. The records are also used constantly to answer questions and guide the actions of public agencies, agricultural and commercial organizations, and individuals. Their records also form a basis for preparedness for national and local emergencies, such as flooding.

Our most frequently asked question this summer at the Regenstein Fruit & Vegetable Garden: why no apples?

Turns out the weather played a major role.

Last winter’s long, deep cold meant very few flower buds. Then, in spring, when pollinators should have been out to feast on apple flower nectar, the weather was chilly. Since bees don’t fly when it’s less than 40 degrees Fahrenheit, little pollination took place. No pollination means no fruit.

Add to that a second factor: apples typically have a two-year boom-bust cycle for fruit bearing. After a bumper crop in 2013, we expected a smaller harvest this year—made even less by the weather conditions above.

Star Appeal for the Holidays

Bling in the season with a striking wreath of your own creation!

Adriana Reyneri —  November 14, 2014 — Leave a comment

You don’t have to be Martha Stewart to fashion this charming star-shaped wreath from branches, raffia, zip ties, and a little duct tape.

Just follow these step-by-step instructions from Heather Sherwood, one of our very creative senior horticulturists, to get your own star appeal for the holidays. Heather has selected red-twig dogwood (Cornus sericea) for its warm, cheery color, but the star can be made from any combination of branches and natural materials, including evergreens (such as junipers) and corkscrew willows. If taste dictates, you can bling out with bells, bows, glitter, or other embellishments. Here’s how Heather does it:

Difficulty Level: Intermediate
Time Needed: Two Hours

Materials:  

  • Heavy scissors
  • Pruning shears
  • A large working surface
  • Five heavier red-twig dogwood branches roughly 3/8” in diameter, cut into equal lengths. Heather recommends 30-inch lengths for a front door wreath. You can use shorter lengths to make a smaller star. This will use less plant material and may be quicker and easier to assemble. The base can also be constructed of wooden dowels.
  • Five 4-inch lengths of duct tape  (Heather recommends black.)
  • 20 plastic zip ties (Heather likes 6-inch ties, but shorter ones will do.)
  • Five 1½-inch bundles of red-twig dogwood branches cut in roughly 22-inch lengths (or slightly more than two-thirds of the length of the base branches)
  • Five 1½-inch bundles of twigs cut in roughly 11-inch lengths (or slightly more than one-third of the length of the base twigs)
  • Roughly 90 36-inch lengths of raffia
  • An 8-inch length of floral wire to create a loop for hanging
  • A strand of Christmas lights and additional 8-inch lengths of floral wire (optional)


To Make the Base:

You will need the five heavier branches, duct tape, and zip ties:

  1. Connect the five base branches into one long strand, using the duct tape to create “knuckle” joints: Place the end of the first branch 1 inch away from the top of the duct tape. Position the branch so it covers one-third of the width of the strip. Place the second branch opposite the first branch, leaving a gap between the two branches. Wrap the 1-inch end of the duct tape around the branch ends. Take the longer length of duct tape and wind it around the ends in the other direction. The joint should bend at the gap in the tape between the two branch ends. Create three more joints so that the five base branches form one very long, bendy stick.
  2. Twist into a star: Hold each end of the long, connected stick and bend the first and last joints, creating a rough pentagon shape. Fold the right side of the pentagon over, then the left side. The base twigs should fall into a rough star shape.
  3. Create the final joint in the star: Notch both ends of the last piece of duct tape so it resembles a knuckle bandage. Hold the loose ends of the base sticks together, forming the last point in the star. Center the duct tape under this point. Wrap duct tape ends, one by one, around the point.
  4. Check to see that all five arms of the star are level and even. Rotate star to double check spacing of the points. Adjust as needed.
  5. Use zip ties to secure the base: You’ll see that the base branches intersect to create a pentagram in the center of the star. Loosely wrap a zip tie around each of the intersecting branches at each of the five angles of the pentagram, making sure the ties pull to the back of the star. Check again to make sure the star points are level and even. Tighten the zip locks. If you’re using freshly cut wood, remember that it will shrink and lose diameter.
PHOTO: Place two branch ends together with a gap of 1/2 inch, and tape together with duct tape.

When creating the branch joints, leave a gap between the ends when taping them together, so that the finished joint will bend.

Make the top layer:

You will need the longer and shorter bundles of branches, zip ties, raffia, floral wire, and optional Christmas lights.

  1. Start with the longer bundles of twigs: Lay the first bundle along a base branch, positioning the cut edges just past the inner edge of the inner pentagram. The uncut edges should extend 2 to 3 inches past the point of the star. “I want the stems to ooze around the base,” explains Heather. Secure the bundle with zip ties at two points, the middle of the pentagon, and the middle of the star point. Make sure the zip ties pull to the back of the work. Continue around the base branches, so that the pentagram and one side of each star point are covered with branches.  
  2. Secure the shorter twigs. You’ll arrange the shorter twigs in a similar fashion, laying the cut edges on the outside edge of the pentagram with the natural edges covering the star point. Blend the cut edges, to give the star a woven look, and fan out the natural edges to soften each star point. Secure the shorter branches with one zip tie in the center of the star point.
  3. Double-check the placement of the bundles. Tighten and trim the zip ties.
  4. Cover the zip ties with raffia: Heather has chosen a simple look, tying the raffia in the back with a square knot. You may decide to pull the knots to the front, tie the raffia in a bow, substitute ribbon for the raffia, or add other types of embellishments.
  5. Using four to five strands held together, wrap raffia around once and tie in the back. Continue winding the raffia around and around until it completely covers the zip ties and creates a nice, thick band around the bundle. Tie in the back and trim. Continue until all the zip ties are covered.
  6. Use floral wire to create a loop to hang your star.

Add lights!

You can backlight your wreath by securing a strand of holiday lights along the back of the base branches. Lay the strand along the star outline and secure it with floral wire threaded between the base sticks and the stick bundles.

It’s like having a time machine—supercomputers and gene sequencing allow scientists to study early events in plant evolution. 

One of our conservation scientists, Norman Wickett, Ph.D., is co-leader of a global initiative involving some 40 researchers on four continents. The team has spent the past five years analyzing 852 genes from 103 types of land plants to tease out early events in plant evolution. The results, published recently in the Proceedings of the National Academy of Sciences, expand our knowledge of relationships among the earliest plants on land.

It was on a seasonably pleasant day this past May that 15 veterans from the Thresholds Veterans Project began a journey to be well in the Buehler Enabling Garden.

PHOTO: Chalkboard plant pot.

Inspirations: “Keep Going” planter, with a side of coffee.

We toured the garden, got to know each other, and sipped on coffee. Lots of coffee. The activity I led was called Inspirational Herb Dish Gardens and was intended to provide these vets with a lovely planter of kitchen herbs to cook with, as well as a message of encouragement they could reference for inspiration in their daily life. After the first retreat was done, I thought to myself, “Wow! That was a really good program!” And it was. It was really good. Over the course of the summer, these vets returned to the Garden five more times to participate in various retreats all focused on wellness and using nature to heal.

To date, more than 2.7 million people have served our country during the most recent conflicts. Approximately 1 million of these veterans have accessed the VA healthcare system for war-related injuries. Many of the injuries sustained on these missions are unique in that they are “invisible” wounds of war—traumatic brain injury (TBI) or post-traumatic stress disorder (PTSD) are difficult to diagnose, yet have large impacts on a veteran’s life. Symptoms range from mild to severe and include anxiety, hypervigilance, insomnia, irritability, and physical pain. Other common injuries sustained from these missions include musculoskeletal and missing limbs. For some, reintegration into civilian life, family, society, and employment may be difficult. In fact, even vets who were not technically injured in war often experience anxiety, hypervigilance, insomnia, and other stresses that inhibit their readjustment.

PHOTO: Vets gather in the garden, discussing plans.

Growing more than plants in the garden; friendships and individuals flourished this summer.

Veterans who have not had success with traditional medicine often begin to seek out alternative ways to heal. That is where the Garden comes into play. We believe beautiful gardens and natural environments are fundamentally important to the mental and physical well-being of all people. We also believe people live better, healthier lives when they can create, care for, and enjoy gardens. I witnessed the amazing effects interacting with nature has on people this summer as veterans—some on the verge of homelessness—planted the Buehler Enabling Garden with summer annuals, overjoyed to return and observe the garden flourishing throughout the season. I witnessed veterans—some participating in in-patient psychology programs—get a pass from the hospital to come to the Garden and learn to rake a dry garden in the Elizabeth Hubert Malott Japanese Garden. I witnessed veterans—some clinically depressed—smile and laugh, as they dug potatoes from the ground in the Regenstein Fruit & Vegetable Garden.

Veterans dig deep for potatoes and for well-being.

Each of our six retreats was filled with creativity, education, companionship, and joy. As the summer progressed, so did the veterans, each of them growing stronger and more healthy in their special way, each of them changing and striving to be well. Our group started to call the Enabling Garden “our garden,” and the plantings we planted became “our plants.” Participants would tell me that this day (the day they came to the Garden) was the day they looked forward to the most. They would tell me how amazing the Garden is, and how safe they felt here. It was music to my ears, and I felt so proud of them.

It was easy to draw comparisons about healing, being well, and growing to gardens this summer. Gardens start small and respond to weather and temperature. They grow and change with the season. Sometimes they start to fail or get crowded out, or overgrown; sometimes they need to be watered or groomed to flush out new growth and blooms. With care and attention, however, they grow, and flourish, and bloom. They are like us. We are small sometimes. We are big sometimes. We respond to things that happen to us or things we do. But with love and care and attention, we can grow, we can bloom, we can be well. Gardens start over and each year is a new year. We can start over, too, and each day is a new day.

PHOTO: Veterans planting in the rain.

I saw this summer how powerful gardens can be in helping people to heal and maintain wellness. Our program was effective because it created a sense of belonging and comradery, and fostered a feeling of continuing to serve, which is an important value to many vets.

As Veterans Day approaches, remember the people who have served, put their lives on the line, and are still fighting today. Thank them, salute them, and honor them.

I was honored to work with this amazing group of veterans, who became an inspiration in my own life. And I am so grateful to have the opportunity to deliver such a wonderful program.
