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. Look for young seedlings in the spring. Pale-leaved Sunflowers spread by rhizomes. If you discover them in an area of the garden where they are not welcome, keep in mind they are easy to remove. 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 and provides the opportunity for the native sunflowers to "stretch out".
