Each year’s Orchid Show at the Chicago Botanic Garden features something new and dynamic—and each year, the Lenhardt Library’s Orchid Show exhibition showcases something rare and dynamic.
Free Talk on Sunday, February 26, at 2 p.m.
This year’s exhibition, Orchidpalooza: Illustrated Orchid Varieties, features five unsigned, untitled, and unnumbered artist proofs that are attributed to English landscape artist Henry Moon (1857-1905). The proofs were most likely intended for a third series of a collection called Reichenbachia: Orchids Illustrated and Described, commissioned by Frederick Sander (1847-1920). Moon was Sander’s son-in-law and was responsible for the 192 chromolithographs published in the monumental two-volume work. This work is considered Sander’s homage to Heinrich Gustav Reichenbach (1824-90), the “Orchid King” who succeeded John Lindley (1799-1865), the “Father of Orchidology,” as the leading orchid authority of the late 1800s.

Never before exhibited in the Lenhardt Library, the five botanically accurate orchid chromolithographs include color bars from eight to twelve colors, registration marks, and scientific names penciled in the margins or on the verso.
The late February weather in Chicago has been a glorious time to be outside and work in the garden. But the unseasonably warm weather has also raised questions about the long-term effect on plants and what garden tasks are appropriate.
It is best to hold off on doing any detailed clean up of garden beds as the mulch and leaves in the beds will provide some protection to any early growing perennials when the weather eventually turns cold again. Raking leaves off the lawn and cutting back perennials are all fine to do now providing your garden soil is not too wet.
Early flowering bulbs like snowdrops that are in flower here at the Chicago Botanic Garden are very tolerant of the cold. Daffodil and tulip foliage is coming up; these might end up being damaged by a spell of cold weather, but this should not affect the spring flowers. You do not need to take any special maintenance steps to protect these plants.
If you have some perennials that are growing in a warm area of the garden with more pronounced growth, they might benefit from a light layer of mulch. For the most part, though, there is nothing special for most gardeners to do in their perennial beds.
This is great weather to prune but proceed with care. Spring flowering shrubs like viburnums, lilacs, and forsythia set their flower buds last year so pruning done at this time of year will remove flower buds and reduce the number of spring flowers. You can still prune—just be aware of the flower buds as you are pruning. Forsythia flowers along the stems while viburnums will have a flower bud at the ends of the stem.
The dormant season, and in particular late winter, is the best time of year to complete rejuvenation pruning, which is the aggressive pruning of overgrown shrubs to bring them back into scale with the garden. Shrubs like hydrangea (except oak leaf hydrangea), potentilla, and spirea that flower on new wood respond well to pruning now too. For instance, I cut my Annabelle hydrangea back to the ground each spring.
Any plants installed last summer or fall should have been mulched when they were planted. If they were not, then mulch them now to help mitigate the temperature swings in the soil and prevent frost heaving of any plants in spring. The freezing and thawing of the soil can push recently installed small plants such as 1-gallon perennials or ground covers that were grown in containers out of the soil as the weather transitions to spring.
If we receive a good covering of snow, the snow itself will not harm plants unless it builds up on them and breaks branches. It is a good idea to brush plants off during a storm if you observe them getting weighted down. Later snowstorms are more likely to come in wet and heavy. Leave the plants alone if the snow has frozen on them to avoid breaking branches during the removal process.
Enjoy the warm weather and the early blooms, both at the Chicago Botanic Garden and in your own backyard.
The arrival of seed catalogs in mailboxes ranks as one of the most hopeful times in a gardener’s year, as it provides us with a welcome link to spring.
One of the first considerations is deciding what to grow. This can be answered by simply listing the veggies or asking your family to name the veggies they like to eat. There are a few other considerations before placing your order for next year’s garden—such as deciding if you should plant seeds or transplant vegetable starts. Seeds of many vegetables can be sown directly in the garden, including root vegetables like carrots, radish, and beets. Peas, beans, and squash are also best directly sown. Cabbage, tomatoes, and peppers are better given a head start inside first, and then transplanted into the garden as small plants, because they need a long, warm growing season.
Timing is important in the vegetable garden, and knowing that our growing season has approximately 170 frost-free days helps guide decisions on which plants to plant and when to plant. Our risk of frost is generally from October 15 through April 27, but can vary two weeks in either direction. Understanding that vegetable varieties have varying tolerances to frost helps you plan your planting calendar. For example, those very hardy plants like collards, kohlrabi, kale, spring onions, pea, spinach, turnip, and cabbage can be planted out four to six weeks before our last frost date. Those called “half hardy” or “frost tolerant”—such as beets, Swiss chard, carrots, cauliflower, and mustard—must be planted a bit later; two to three weeks before the last frost date.
The best seed catalogs will help decipher a gardener’s questions, and help plot, measure, and sort out the seed math needed to get started on a vegetable garden. Most seed is available in organic and non-organic options, with the latter usually the least expensive. Good catalogs provide keys to help decipher the icons (vegetable resistance codes) in plant descriptions. After all, a seed company’s success is based on a gardener’s success with their products.
As our nutritional consciousness rises, the taste and the health benefits of growing your own organic produce is a pursuit worthy of winter afternoons spent planning.
Here are a few of my favorite seed companies: (Consider going paperless; all of these catalogs are available online.)
Johnny’s Selected Seed is a 43-year-old, employee-owned company in Maine, recognizing that “good food is the basis of our well-being.” Widely used by home gardeners and small market farmers, the seed selection includes hundreds of vegetable, flower, and herb varieties in organic and non-organic (options) seeds. The catalog provides grower’s information for the novice to advanced gardener—it’s a virtual garden education. Johnny’s provides well-tested tools for garden tasks from bed prep to trellising, to season extension, and cover cropping. Comparison charts like the one on leaf lettuce help gardeners select seeds based on their specific growing conditions. Charts and photos compare length, width of mature veggies, and harvest windows.
High Mowing Organic Seeds simply provides 100 percent certified organic, non-GMO Project Verified vegetable and flower seed to organic growers. Seed definitions of open pollinated (OP), heirloom, and hybrid seeds are aptly explained and marked throughout. Crop types are headed by general cultural information or the “how to” grow beans for example. Then each listing is complete with the days to maturity (based on conditions in Vermont where HMO is located), disease resistance and any special attributes of the plant including breeder credit. High Mowing Organic Seeds is an excellent resource for passionate organic growers.
Burpee acquired The Cook’s Garden more than ten years ago, and it has helped nurture America’s love affair with healthy, delicious food by offering the best gourmet veggies, greens, and herbs from around the world.

The not-for-profit’s mission is to conserve and protect America’s culturally diverse but endangered food crop heritage for future generations by collecting, growing, and sharing open pollinated seeds and plants—check the website for availability updates. The catalog contains an anthology of stories and fascinating anecdotes connecting the reader to plant history, and has a comprehensive roster of vegetable seed many of which are certified organic. Be sure to check out the heirloom flower seed, garlic, and seed potatoes. It’s a great resource for seed saving supplies and helpful guides to get started planting and seed saving.
Pinetree has been a year-round source for the home gardener for more than three decades. Their product lines go well beyond a fairly complete line of gardening gear, including soil kits and amendments, and animal deterrents. Also offered are natural bath and hair products, kitchen gadgets (I want the tortilla press), and bee, bat, and bird products. If you’d like fragrant oils and herbal teas to go along with your vegetable seeds, look no further than Pinetree. There is a comprehensive compendium of some of the best gardening books that I’ve seen.
Baker Creek offers 1,800 vegetable, flower and herb varieties claimed to be the largest in our country. A focus on preservation, it not surprising they have one of the largest selections of seeds from the nineteenth century. The fittingly named Rare Seed Catalog is like the Vogue magazine of the vegetable world. It wins the prize for the most beautiful photographs of the most avant-garde produce collection, complete with nutritional factoids and culinary inspiration. Stories from seed collecting expeditions around the world—recently Thailand, Myanmar, and India—are in the Heirloom Gardener, an associated and nationally distributed magazine written as a tool to not only promote and preserve our rich agricultural history but as explanation of why we need to care about it. The Rare Seed Catalog provides a selection of 78 varieties of melon and 20 types of okra. Baker Creek has a limited but diverse availability of live plants to ship. If goji berries, ginger root, and dragon fruit tickle your fancy (and you either live in the subtropics or have a greenhouse available) look no further, they’re in the Rare Seed Catalog. Baker Creek encourages political activism, and the catalog is written with an underlying ripple that we’re reaching the tipping point in the struggle against GMOs.

Varieties/cultivars and tips for direct seeding into spring gardens
It’s hard to resist a list of a few of my favorite varieties to directly sow into the spring garden. Knowing how much seed will sow a 10-foot row and the days to maturity (when the harvest can be expected) is the type of garden math that tangles up many a gardener, but quality catalogs will provide vegetable grower’s guides to help to sort out how much seed you’ll need.
Radish: Direct-sow spring radish as soon as the ground can be worked, or four to six weeks before the last frost. Radish is best grown quickly in cool, damp conditions. It’s easy to grow, and requires only 28 days from planting to harvest. Try these spring radish cultivars: ‘Early Scarlet Globe’, ‘Rudolf’, and ‘Crunchy Royale’.
Beets: Nothing says spring like tender, freshly harvested baby beets. Sow about two weeks before our last frost date and thin to 3 inches between seedlings. Fertilize with liquid seaweed. Beets have great culinary versatility, so plant a combination of gold and red. ‘Detroit Dark Red’, ‘Bull’s Blood’, and ‘Burpee’s Golden’ are great choices.
Swiss chard: We love ‘Rhubarb’ and ‘Five colored Silverbeet’. These greens can grow through the entire gardening season. By harvesting just the outer leaves with a harvest knife, the plant stays in place and the integrity of your design stays intact.
Carrots: The sweetest, juiciest, and most flavorful carrots are the French heirlooms. Sow two weeks before the last frost date. Carrot is slow to germinate, so have patience. Our favorite varieties for Chicago growers: ‘St. Valery’, ‘Paris Market’, and ‘Scarlet Nantes’.
Spinach: One of the earliest-germinating cool season vegetables, spinach can be direct sown in 2-inch bands or rows four to six weeks before the last frost. Plant ‘Corvair’, ‘Tyee’, or ‘Donkey’ for the most reliable spring crops.
Lettuce: We love ‘Tennis Ball’, ‘Black Seeded Simpson’, ‘Rouge d ’Hiver’, and ‘Winter Density’. One gram of seed will sow a 15-foot row.
Spring greens: Try mache, arugula, or mizuna; 30 to 50 seeds will seed one foot of row when sown as a cut-and-come-again salad mix.
Take a sneak peek behind-the-scenes at the Orchid Show, the Chicago Botanic Garden’s biggest flower show of the year. Buy tickets here.
We’ve rolled out the tall ladders, prepped hanging baskets with Spanish moss, and worked hard to keep 10,000 warmth-loving tropical orchids happy (including an orchid that is rarely shown in the United States, Phalaenopsis Sogo Yukidian ‘V3’; be sure to check out the unusual number of big blooms on each spike).
It’s all hands on deck for the Show, which runs February 11 to March 26, following the Members’ Preview night on Friday, February 10. Volunteers across the Garden and beyond have pitched in to help from departments including Education, Model Railroad, and Horticultural Therapy Services, along with our Woman’s Board.
It all starts with ideas from our creative team, which starts brainstorming shortly after the end of the previous year’s Orchid Show.
In the completed archway, supporting vines are woven together and attached to a hidden framework. Notice the dangling aerial roots from orchids that are epiphytes—plants that grow on trees, with above-ground rather than in-ground roots.
Sometimes, things don’t always go as planned. Work on the 13-foot high orchid “wind chime” got delayed while we waited and waited for a delivery of bamboo supports from Colombia… Luckily, the shipment arrived before the Show.
When you walk into Nichols Hall, don’t forget to look for the dozens of blooms overhead.
This year’s theme is Orchids in Vogue, a playful look at the influence of orchids in popular culture, including fashion. Last summer, senior horticulturist Salina Wunderle came up with an idea for an orchid “dress.” Now we have three design teams working on orchid dresses; come see the final result.
