Propagation Notes Pale-leaved Sunflower
We have had a great deal of success propagating these native, Ohio, perennial, sunflowers simply by allowing them to self seed in the fall, then transplanting young seedlings in the spring.
Pale-leaved Sunflowers also spread by rhizomes, luckily they are easy to remove if found wandering into a section of the garden where they are not welcome. Although I must say they really don't roam outside their designated area. My guess is the birds gobble the seed before it has a chance to germinate. On the other hand customers have told me this plant is too aggressive for their taste. My recommendation would be to choose a location in your yard that has filtered shade and is well drained the give the luxury of spreading their wings! Or in this case rhizomes.
