Sonja Sunflower Seed

Item #HSC-SUN-041-250S

About this variety

A tangerine branching sunflower for cutting.

Sonja is a well-branched plant that sends up a spray of eight-plus sturdy flowering stems, 17 to 28 inches long, each finished with a 4" tangerine bloom around a dark center. Cut stems last a long time in water.

It is day-length neutral, so it blooms on schedule early or late in the season. It carries pollen, so bees visit it.

Blooms about 70–85 days from sowing on plants 38–42" tall. Open-pollinated.

Know before you sow

Quick Facts

Growing times vary with weather, soil and local conditions.

Growing guide

From seed to harvest

Sow after frost

Direct sow 1/2" deep in full sun; seedlings appear in 7–14 days.

Give them room

Space branching plants 18–24" apart in light soil, and go easy on nitrogen.

Pinch for more stems

Pinch young plants to encourage side shoots; resow every 2–3 weeks.

Cut early or late

Harvest from first color to nearly open; let blooms open fully for drying.

Growing Information

Days to germination

7–14 days at 70–75°F (21–24°C).

Direct sowing (recommended)

Sow 1/2" deep once frost is past.

Transplanting

Sunflowers resent root disturbance, but a first planting started in 50- to 72-cell trays 2–3 weeks ahead and then set out can give you the earliest blooms.

Pinching

Pinch branching varieties when young; they respond with more side shoots and longer stems.

Succession

Sow again every 2–3 weeks, or grow several varieties side by side, to keep cutting all season.

Light

Full sun.

Plant height

38–42".

Plant spacing

18–24", which leaves room for the side branches.

Hardiness

Grown as an annual.

Harvest

Cut anywhere from tight bud with the first color showing to nearly open, depending on your market and how you will use them. For drying, wait until flowers are fully open, then hang them or dry them in silica gel.

Soil

Light, well-drained soil. Too much nitrogen pushes rank growth and can distort the flowers.

Notes

Spacing, temperature, soil and day length all affect bloom size and stem thickness. For very early or late crops, choose day-length-neutral varieties or ones noted as flowering under short days. Single-stem sunflowers give only one bloom per plant, while branching types keep producing side stems.

Uses

An excellent cut flower, and showy in the garden.
