I received these seeds recently and would like to know a little more about them. Like when they should be planted outdoors and how much water they require. I would also like to know how tall they grow. Thank you for any help you can give me.

Reseeding annual, California native. 1'-2' tall. Rich moist soil, full sun in cool summer areas and part shade where summers are hot. Direct sow in late Fall or in Spring, seedlings are not frost hardy. Surface sow or only barely cover seed.

Thank you so much for helping me with these. If the seedlings are not frost hardy I think I need to wait until mid spring in my area.
