Description

Plants are tall, with outward-facing blooms and a vigorous branching habit ideally suited for flower arranging. Flowers have tubular quilled petals and dark chocolate centers in a mix of pale lemon-yellow dusted with cocoa and raspberry—coloring similar to that of ‘Sahara’ black-eyed Susans. Plants make great screening and attract birds.

Site: full sun
Days to maturity: 60 to 65 days
Plant spacing: 18 to 24 in

Seed Sowing & Growing Notes

Sunflowers can be direct-seeded into the garden after all danger of frost has passed or started indoors in trays and transplanted out after 2 to 3 weeks.

Harvesting/Vase Life

Harvest as soon as the first petals on a bloom start to lift off the central disk. Strip three-quarters of the leaves from the stem. Expect a vase life of 7 to 10 days.
