Growing Information
How to plant:

Propagate by seed - Start seeds indoors 4 weeks before the last frost. Cover them with soil, since light inhibits their germination. Can also be sown outdoors after the last frost. Pre-started plants are often available at retail outlets.

Germination temperature: 65 F to 70 F

Days to emergence: 14 to 21

Maintenance and care:
May need staking. Requires regular watering. Plants purchased in cell-packs with crowded roots may develop slowly or may not develop at all if the crowded roots stop growing.
