Since this it has reliably returned and self-seeded along the path here-and-there, but is not aggressive and never need any care. I mean literally ZERO care. I never cut it back, water it, fertilize it, weed it nada, nothing. It has no serious insect or disease problems plus a long blooming period. Occasionally, a stem falls over into the pathway. I simple step on it and keep going -- it is that resilient.
If you are looking for a native wildflower to plant that is truly no-maintenance, Spiderwort is a great choice.
Wildflower Wednesday is about sharing wildflowers from all over the world. It was started by Gail Eichelberger on her "Clay and Limestone" blog. It is always on the fourth Wednesday of the month.
