We stopped by the Production Greenhouses to see what they are growing for the upcoming spring garden displays. Tim Pollak, Outdoor Floriculturist, said we are growing 66,000 spring annuals and vegetables onsite this year for displays in the ground, in hanging baskets and containers.
Tim explained that the foxgloves you will see in the Circle Garden and Rose Garden were started from seed in October, grown at 42 degrees F for six weeks and brought into the greenhouse in January to grow with long days and warm temperatures to get them to bloom earlier than usual. The lupines you will see in the Heritage Garden and English Walled Garden are two years old and we plan to return them to the greenhouse for many years so they will continue to grow in size. The penstemon you will see in the Circle Garden have been growing for one year to get them to size, then overwintered in a nursery quonset and brought into the greenhouse in January to grow with long days and warm temps to get them to set flowers. Now, they are back in a quonset to slow their flowering until they are planted outside.
We are growing several species of echium (tower of jewels) for displays outside the Visitor Center as well as in the Heritage Garden and English Walled Garden. Most of the plants shown here were started from seed 18 months ago to get them to flower this spring. Echium fastuosum will grow 5-6 feet tall outside the Visitor Center, whereas Echium pininana will grow 12-14 feet tall in the Heritage Garden.
What are you most looking forward to seeing this spring?
