Rainy Side Notes
I don't know what it is about contorted trees that grabs me, and makes me feel all twisty with excitement inside. When Robinia 'Lace Lady' attracted my attention, at the Monrovia display garden in Oregon, its contorted branches and leaves were curling every which way.
This small tree, a wonderful focal point in any garden, provides fragrant, spring flowers, unusual leaves for summer interest and twisted branches for year-round intrigue. In addition, it is just as handsome planted in a container sitting on a deck or patio. The tree is drought tolerant once established, which is a bonus during our annual drought in the Northwest. Adaptable to almost any soil type except permanently wet ones, Robinia 'Lace Lady' fixes its own nitrogen supply.
