Threadleaf Coreopsis
Coreopsis verticillata
A long-blooming native with clouds of soft yellow daisies all summer over fine, threadlike leaves, bright in a sunny border, rock garden or pot. It thrives in heat and poor, dry soil that drains, and deer leave it alone. Go easy on water and fertilizer, and expect it to spread slowly into a wider clump.

Spacing

Place a row in your own yard and VeraScape spaces them at their mature width, so you can see whether they’ll crowd the walk.
