An occasional wildflower of coastal dunes from Pinellas & Hillsborough Counties south into Lee County.
Helianthus debilis vestitus is one of three subspecies of dune sunflowers in Florida. Stems are decumbent, hairy, variously described as hirsute or villous, with ascending to erect flowering branches. The leaves are widest near the base, not constricted in the middle and gradually tapering towards the tip, coarsely and irregularly toothed with the underside densely gland-dotted. Peduncles are 9-15cm (3-1/2 - 6 in.) long. Flowers have yellow rays 12-16mm (<1/2 - 5/8 in.) long and dark disks 11-12mm (~7/16 in.) in diameter. West coast dune sunflower may flower all year.
