Harvest Tips
Dyssodia is primarily grown for ornamental flowers rather than harvest. For cut flowers, harvest stems in early morning when flowers are fully open; they last 5-7 days in a vase. For seeds, allow some flowers to fade and dry on the plant; collect seed heads when papery and dry, then crumble to harvest tiny seeds.
Fun Facts
- 🌱 Dyssodia is sometimes called 'Dahlberg daisy' in honor of Swedish botanist Anders Dahlberg, though it is not a true dahlia.
- 🌱 The pungent aroma of Dyssodia foliage comes from essential oils that increase in intensity when leaves are crushed, and this scent has been shown to deter certain insects naturally.
- 🌱 In its native range across the southwestern United States and Mexico, Dyssodia is a key late-season nectar source for monarch butterflies during their fall migration.
