In front of the treehouse, Prassas created a mound of meadow grass — Pennsylvania sedge (Carex pensylvanica, zones 3 to 8). “I wanted to create a soft meadow for the kids,” Prassas says.

“This is a shady garden and naturalistic play space. I wanted to add shade-tolerant plants with lots of textures and different-colored leaves,” Prassas says. “These include ferns, hostas, grasses and sumacs that make it more interesting for the kids. Another plant I included is witch hazel, which flowers when nothing else is flowering.” The witch hazel species he planted is Autumn Embers vernal witch hazel (Hamamelis vernalis ‘Autumn Embers’, zones 4 to 8).

Woody plants Passas added to the garden include ‘Little Henry’ Virginia sweetspire (Itea virginica ‘Little Henry’, zones 5 to 9), cutleaf staghorn sumac (Rhus typhina ‘Laciniata’, zones 3 to 8), Snowmound spirea (Spiraea nipponica ‘Snowmound’, zones 3 to 8), bottlebrush buckeye (Aesculus parviflora, zones 4 to 8) and a variety of hydrangeas.
