These dainty little Pom Pom Zinnias have been garden favourites for many years. Flowers bloom in just a few weeks from seed sown outdoors and continue in great profusion until the frosts of fall. Plants grow to 75 cm (2-1/2') tall.
100-200 seed/gram. 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.
