Sunflower seeds — Helianthus annuus from dwarf to giant

Sunflowers (Helianthus annuus) are the easiest big-impact flower you can sow — fast, cheerful and loved by bees and birds alike. They range from knee-high pot varieties to towering giants, all browsable under Helianthus annuus within our flower seed range. They're a brilliant first sow for children and beginners, and our flower growing guide covers the basics.

When should you sow sunflowers? They hate frost — the calendar shows the safe window to start.

Tall, dwarf and cutting types

Giants make a quick summer screen, dwarf kinds suit pots and balconies, and multi-headed branching forms are bred for the vase — find them among our cut flowers. Every type is a magnet for bees, so sunflowers also feature in our pollinator and bee-friendly ranges.

Sowing and growing on

Sow after the last frost into warm soil, or start indoors and harden off before planting out with our hardening-off guide. Tall varieties need staking in exposed spots — see the plant supports guide — and steady moisture from the watering guide keeps them powering upward.

Growing sunflowers for cutting? Pick branching types and sow a fresh batch every few weeks for blooms into autumn.

Frequently Asked Questions

When do I sow sunflowers?
Sow after the last frost in warm soil, or start indoors a few weeks earlier and plant out once frost has passed. See the flower sowing calendar for timing.

How tall do sunflowers grow?
Anywhere from about 40cm for dwarf pot types to over 3m for giant varieties, depending on which you choose.

Do sunflowers need support?
Tall single-stem varieties benefit from staking in windy or exposed spots; dwarf and branching types usually stand on their own.

Are sunflowers good for bees?
Yes — their open, pollen-rich faces are excellent for bees, and the ripe seed heads feed birds in autumn.

Can I grow sunflowers in pots?
Yes, if you choose dwarf or container varieties and keep them well watered.
