Notes
'Dondo White' flossflower (Ageratum houstonianum 'Dondo White') is an annual for borders, containers, and pollinator gardens. It is not cold-hardy and will not survive freezing temperatures. This plant likes full or part sun and average to moist soil of most types. Butterflies and bees visit the flowers, and it blooms from early to late summer. It is not a favorite of deer or rabbits, though hungry ones will eat almost anything.
Pairs well with Purple top, Snapdragon, Prairie Sun rudbeckia, and Silver feather grass.
