Faits intéressants
Woodland Sunflower is hardy and adaptable to varying soil conditions. It may not be ideal for a small garden due to to the fact that it spread easily. Clusters can be separated to control growth. In addition to attracting pollinators, its seeds provide food for animals such as squirrels. Its tall stalks and bright yellow flowers make ideal cuttings to brighten up indoor spaces.
