Helianthus resinosus

Phonetic Spelling
hee-lee-AN-thus res-in-OH-sus
Description

Resinous Sunflower is a wildflower native to several southeastern states.  It can be found growing along roadsides, in pine woodlands, mixed hardwood forests, and thickets.  

Each stem, that can grow up to 8' in height, will produce one head or multiple heads, up to 5.  Each head has 10 to 20 yellow ray petals which are the outer larger petals and over 90 yellow disc flowers, the tiny innermost flowers. 

Self-seeding can expand your garden with this large perennial for years.  It will also multiply by underground suckers.  The suckers can be shared with other gardeners.  Once they have become established, a small trowel can be used to dig them up.  Repot them, giving them time to establish a root system before replanting.  

This plant is sometimes mistakenly sold under the name Helianthus Tomentosus Michaux.

Insects, Diseases, and Other Plant Problems:  Can spread through suckers.
