The Sarah Stevens MacMillan Terrace Garden is the entry garden to the many of the Arboretum’s gardens just off the Morgan Terrace outside the Snyder Building. This garden tries to create the best perennial garden that one could accomplish in Minnesota. A limited color palette of white, pink, blue, purple, and some yellow presents a challenge in late summer and early fall but as one will see, there are still flowers at this time of year. The garden is set off by a circle of green grass which is interplanted with crocus and Siberian squill for early spring bloom. Roses and other flowers are planted in the stepped wall surrounding the garden. There are 115 different kinds of perennials and shrubs in the garden.
