OSC Seeds Zinnia Cactus Flowered Mixed Colours Pkg.

Approximately 100 seeds/package (100-200 seeds/gram)

An extra-large strain of cactus zinnia with flowers up to 15 cm across. The stocky, upright plants first start to bloom when roughly 37.5 cm tall. Plants can grow up to 90 cm in height, producing large quantities of flowers on numerous side branches all season long.

Select a sunny site with well-drained organic soil. Sow seeds in late May when the soil has warmed. Do not be in a hurry, as cool, damp soil often leads to seed rot. Barely cover the seed with soil, and under ideal conditions, germination will occur in 5-10 days. When the seedlings are 7.5 cm tall, thin smaller varieties to 25 cm apart and larger varieties to 35 cm apart. If you wish to start seed indoors, sow seed in mid-March 6 mm deep in peat pots or Jiffy 7’s. A germination temperature of 22° C is suitable. Grow on at 15° C until hardening off and transplanting out in late May.
