Notes
Stiff greenthread (Thelesperma filifolium) is an annual for borders, meadows, and low maintenance gardens. This plant likes full sun and dry soil of most types. The name comes from the thread-like leaves on slender, branched stems. Yellow, daisy-like flowers sit on delicate, leafless stalks and draw bees and butterflies. Deer usually look elsewhere for a meal.
Pairs well with Cherry Brandy rudbeckia, Autumn moor grass, and Six Hills Giant nepeta.
