Brown Eyed Susan / Three Lobed Coneflower
Origins of the Brown Eyed Susan / Three Lobed Coneflower Rudbeckia trilobata:
Allthough native to much of the Eastern United States including Florida, these freely flowering plants
have managed to end up with a status of ‘Endangered-State’ for Florida.
Having grown these for a season, I quickly decided they had their place in any
home landscape. They bloom freely in summer when other flowers begin to fade out from the heat and
require little in the way of maintenance. It is an easy care perennial plant, that attracts butterflies
and other pollinators, and birds love the abundant seeds. Add to that it’s resistance to drought,
pests, foraging deer, Florida’s excessive heat and you have a busy gardeners dream plant!
