Annual (4 in/10 cm) 79,000 seeds per oz/28 gr.
GREENHOUSE: Sow Feb. 1st. to Apr. 1st. for May blooms. To skip transplanting sow as thinly as possible (1 oz/28 g per 60 flats - 12x20 in/31x51 cm @ 1,000 seedlings per flat). Seed should germinate in 5 days @ 60°F/16°C soil temp. Grow seedlings at 50-55°F/10-13°C. Use soil low in pH (especially blue alyssum). Plants are easily stunted by rich soil. Shade blue and pink types with cheesecloth to prevent bleaching.
DIRECT SOWING: Sow outside in late May. Cover 1/8 in/3 mm deep with fine soil, firm well. Thin seedlings in clumps, 6 in/15 cm apart, 3 weeks after transplanting. Blooms 6 weeks from seed.
