Early blooming, semidouble flowers.

Golden-yellow petals surround green centers. 4–6″ blooms on 12–

24″ stems. Downy mildew-resistant plants have a sturdy, branching habit. Pollenless. NOTE: Downy mildew in sunflowers persists in infected soils and is especially problematic in cool, wet soils. Symptoms include damping-off, stunted plants, yellowing leaves, and the presence of downy, white mildew on the undersides of the leaves.

Specs:

  • Plant Height: 60–72″
  • Packet: 50 seeds
  • Avg. 800 seeds/oz

Size

Packet, 250 Seeds, 500 Seeds, 1,000 Seeds

DAYS TO GERMINATION

7-14 days at 70-75°F (21-24°C)

SOWING

Direct seed (recommended) – After last frost, sow ½" deep. Transplant – Sow into 72 to 50-cell flats 2-3 weeks prior to planting out. Plants dislike root disturbance but sowing indoors and then transplanting the first crop outdoors can be a successful way to get first-early sunflowers. Pinching branching varieties is recommended to encourage branching and longer stems. Succession-sow every 2-3 weeks and/or plant multiple varieties for continued harvest.

LIGHT PREFERENCE

Sun.

PLANT HEIGHT

Varies.

PLANT SPACING

18-24".

HARDINESS ZONES

Annual.

HARVEST

Flowers can be harvested tight, when color first shows, or when almost completely open, depending on your market and preferred use. Dried – Flowers are completely open. Hang or use silica gel.

SOIL REQUIREMENTS

Light, well-drained soil. Excessive nitrogen may cause plants to grow too vigorously with abnormal flower shapes.

USES

Excellent cut flower. Single stem sunflowers can make a beautiful and reliable display in the garden but please note that they will only provide one bloom form each plant.

NOTES

Flower size and stem diameter are controlled by plant spacing, temperature, soil type, and day length. For early and late season production, select varieties that are day-length neutral or are noted as suitable for flowering under short days.
