Zinnia - Giants of California Mixed (Seeds)

Description

Immense, double flowers 12.5-15 cm (5-6″) across form on plants growing to 90 cm (3′) tall! The overlapping petals are more loosely placed than the dahlia flowered types and the flowers themselves are much flatter – generally about 2.5 cm (1″) thick.

How to Grow

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 (3″) tall, thin smaller varieties to 25 cm (10″) apart and larger varieties to 35 cm (14″) apart. If you wish to start seed indoors, sow seed in mid-March 6 mm (1/4″) deep in peat pots or Jiffy 7’s. A germination temperature of 22 C (72 F) is suitable. Grow on at 15 C (60 F) until hardening off and transplanting out in late May.
