Answer: It appears that Ice plant takes a while to get to the flowering stage so you should start them indoors about 10-12 weeks before the last frost. They like full sun and dry soil. If you sow them outdoors, I can't say they'll make it to flowering in oneseason. They are perennial in zones 9-10. Gomphrena should be started about 6-8 weeks ahead of time indoors. If sown outdoors, sow after last frost. Torenia should be started 6-8 weeks ahead of time. For outdoor sowing wait until 1 week after last frost. Each seed packet should tell you when to start the seed.
