Bulbs Blooming, Spring through Fall

In this class, Courtney Locke, bulb grower and Staff Horticulturist, will discuss the world of bulbs beyond tulips and daffodils. Although the latter are beautiful and deserve attention, there are many varieties that bloom later into the summer and fall. Aconites, Camassia, and fall crocus are just a few that will be featured. Courtney will take you on an online visual journey; learn how to landscape with these bulbs, including naturalizing or gardening within an ornamental border, and how to manage bulb species over time—most bulbs are perennials, perfect partners in sustainable gardening.

Make a Container Water Garden

Water gardens are growing in popularity for a number of reasons: to attract wildlife like birds and butterflies, to add a melodic sound feature, to contribute light reflection, to offer a place for personal respite, and to cool down a garden space. Water gardens that incorporate unique and lush plants add bold shapes, forms, colors, defined lines, and textures to a garden space. In class, students will make and take home a small water garden container filled with personally selected plants supplied by the Gardens. We'll talk about the wide variety of plant options, materials, and different kinds of water garden designs. While this class is a part of our adult education offerings, it is open to advanced younger students, ages 14 and older.
