A seed worth growing
A compact, disease-resistant dwarf zinnia for beds and pots.

Know before you sow
Growing times vary with weather, soil and local conditions.
Sow in 72-cell trays about 4 weeks before planting out and cover the seed; 80–85°F gives sprouts in 3–5 days. Do not let roots get pot-bound.
After frost, in full sun, 9–12" apart in fertile soil with pH 6.3–6.8.
Pinch the first bud for branching and sow or plant every 2 weeks for a steady supply of stems.
Cut before blooms open fully, when the stem is firm right up to the flower. Expect 7–10 days in the vase.
3–5 days at 80–85°F (27–29°C); slower, about 5–7 days, at 70–75°F (21–24°C).
Sow into 72-cell trays or similar containers about 4 weeks before planting out, and cover the seed. A heat mat makes it easy to hold the right temperature. Plant out before the roots fill the cell and handle them gently: stress from transplanting can make double-flowered zinnias produce single blooms for a while.
Sow 1/4" deep once frost danger has passed; zinnias are very frost-tender.
Sow or plant every 2 weeks for a long run of top-quality stems. Pinch out the first bud or bloom, then keep deadheading to encourage branching and more flowers.
Full sun.
About 12–20" tall; staking is not needed.
9–12".
Grown as an annual.
Fertile soil rich in organic matter, ideally pH 6.3–6.8.
Cut before the bloom is fully open, once the stem feels firm from the cut right up to just below the flower head.
7–10 days.
40–50°F (4–10°C). Colder storage damages zinnias.
Tall varieties are excellent for cutting; also good for beds, borders and mass plantings.
