Updated 2026-05-17 16:59 UTC

Overview

Claret F1 Sunflower is a striking hybrid of common sunflower bred for velvety, deep wine-red petals that develop a subtle metallic sheen as blooms mature. A fast-growing, branching annual, it produces multiple long-stemmed flowers ideal for pollinators and for cutting. Expect robust plants reaching about 1.5–2 m (5–6 ft) tall in a sunny, sheltered spot. Grow it as a summer annual: direct-sow after the last frost for mid to late season color, and enjoy blooms from summer into early autumn. With straightforward needs—full sun, well-drained soil, and deep but infrequent watering once established—this cultivar suits beginners and seasoned gardeners alike.
