In mid-October, the Conservancy oversees the planting of over 11,000 tulips, which are ordered in the summer. When the tulips are in bloom in early May, the sight is quite spectacular. When the tulips die back, they are dug up to make way for the Annual Garden. Bulbs are sold in bags to the public.

For formal gardens, it is better to replant new ones in the fall, as tulips do not always rebloom. At this scale, it is feasible to organize and store them. This also gives us the opportunity to change the colors and patterns. After the tulips are gone, the Annual Garden is planted.
