A seed worth growing
SunFill™ Purple (F1) Sunflower Seed
About this variety
A purple-tinted sunflower for bouquet greenery.
SunFill Purple grows quickly and produces sturdy, geometric heads 3–4" across, green at the center and fading to purple. Sunflower backs can be as striking as their faces. Bred by U.S. sunflower breeder Dr. Tom Heaton, SunFill varieties have ornamental sepals that wrap over the face of the flower, and very few small petals, so the bloom shows that "back of the sunflower" look. Use them as bouquet greenery.
Harvest for cutting only; flowers left standing develop small petals and a big seed head, which changes their look. No pollen; one flower per stem.
Blooms about 50–55 days from sowing on plants 60–72" tall. F1 hybrid.

Know before you sow
Quick Facts
Growing times vary with weather, soil and local conditions.
Growing guide
From seed to harvestSpacing
4–6" apart for cut stems; wider spacing gives bigger heads. Go easy on nitrogen.
Do not pinch
Single-stem types should never be pinched. Sow every 1–2 weeks for a continuous supply.
Harvest
Cut as petals start to lift or when nearly open; for drying, let blooms open fully.
Growing Information
Days to germination
7–14 days at 70–75°F (21–24°C).
Direct sowing (recommended)
Sow 1/2" deep after the last frost.
Transplanting
Sunflowers dislike having their roots disturbed, but for the very first flowers you can sow in 50- to 72-cell trays 2–3 weeks before planting out.
No pinching
Do not pinch single-stem sunflowers; pinched plants give poor flowers or none at all.
Succession
Sow every 1–2 weeks, and/or grow varieties with different days to maturity, for a steady harvest.
Light
Full sun.
Plant height
60–72".
Plant spacing
4–6". Closer spacing gives smaller heads and thinner stems.
Hardiness
Grown as an annual.
Harvest
Depending on your market and use, cut when the petals first show color, or later when the flower is nearly open. For drying, let the flowers open fully, then hang them or dry them in silica gel.
Soil
Light, well-drained soil. Too much nitrogen makes plants overly vigorous and can distort the flowers.
Notes
Spacing, temperature, soil and day length all affect flower size and stem thickness. For very early or late crops, choose day-length-neutral varieties or ones noted as flowering well under short days.
Uses
Excellent for cutting and for the garden.
Scientific name
Helianthus annuus
