No timeline data available yet for this variety.
Sow indoors 6 to 8 weeks before your last frost date. Sow seeds at a depth of 1/8 inch, then cover with vermiculite to maintain humidity during germination. Keep the seed tray at 55 to 65°F. Seedlings should emerge in 7 to 30 days.
Harden off seedlings by gradually exposing them to outdoor conditions over 7 to 10 days before transplanting. Move seedlings outdoors after the last frost date when soil has warmed. Space transplants 10 inches apart in beds prepared with compost.
Direct sow seeds outdoors in early spring as soon as soil can be worked. For continuous color, make a second sowing six weeks later if desired. In mild winter areas (zones 8 to 10), you can also fall sow for earlier spring blooms.
