Sunflower, Ring of Fire (Organic)
Helianthus annus. 70 days.
Bicolored petals are yellow at the tips and dark maroon at the centers. Plants grow to about 5′ tall with lots of branching. The primary flower is 6-8” and plants continue to set many smaller, 3-5″ flowers on long stems through the end of the season, which makes this variety superb for arrangements. Ring of Fire is an All-America Selections winner.
Direct sow 1/2” deep after danger of frost has passed (mid-May). Thin to 18” for largest blooms, decrease spacing for smaller plants. Prefers full sun and protection from wind.
Collect seeds from seed heads that are fully dry. Shell by hand, winnow or screen to clean. Highly cross-pollinating, for pure seed isolate from other sunflower varieties by 1/2 mile.
