Tropaeolum majus. Easy to grow in full to filtered sunlight, it is best to direct-sow in well-draining, loamy soil after the last frost. Plant 1" deep, since they require darkness for optimal germination. Keep uniformly moist until the seedlings emerge, about 10 days after sowing. Weed and keep well-watered until established. Or, start indoors 5 weeks before the last frost date. Sow in a good seed-starting mix at 65° to 70°F. Provide even moisture, strong light and good ventilation. Prior to transplanting, acclimate the seedlings by gradually exposing them to outside conditions for 1 to 2 weeks. Thin or transplant the seedlings 8" to 12" apart in the garden. Drought-tolerant, water moderately once established. They flower best with cooler nights. Summer flowering. Dwarf varieties: 12" to 18" tall. Taller varieties: 5' to 8' tall.
