Swamp Sunflower (Helianthus augustifolius)

$6.00

I’m a native of New York state, and threatened in our state

I’m a late blooming sunflower with lovely dark green leaves and beautiful yellow blooms.

I like sunny and wet habitat.

I attract bees, butterflies and other pollinators, Butterflies like to lay eggs on my leaves, which offers a food source for many bird species.

There are at least six species of specialist bees that only pollinate Helianthus spp of which I am one.

Unlike other Helianthus, I don’t spread aggressively, but prefer to grow in clumps.
