Trial: Annual

Years Trialed: 1999

Good Qualities

Good color (6); Good flower size (6); First blooms July 7. First of trial seeds to bloom. Hugh flower heads 6-8; across; Nice small flowers for bunching alone or with other large flowers; Long lasting, head’s point up or out; Consistent color and growth produced crop that flowered very uniformly; Yield; Good bug damage resistance. Good strong stem. Reliable hold; Good; Very nice sunflower.

Problems

Lodging; Worst at lodging of all sunflowers grown this year; The branching habit could be a problem if you wanted large single blooms–then you’d have to pinch them; Weak stems; None; Height, stem size and small flower for a yellow sunflower; Harvest period is spread out with last few hanging on.

Comments

Similar to Sunbright; Amazingly drought tolerant and heat tolerant. We had weeks of 100°F + temperatures and after 4 weeks of 100°F + days and little water, they finally began to show stress in the leaves, burned margins. No fertilizer or chemicals used; Last one picked the end of September when other growers had none. Used as focal flower in mini bouquets and with a short grass tied with raffia; Not uniform.
