Growing black-eyed susan in zone 10b

(Zone 10b = an average winter low of 35°F to 40°F.)

In USDA zone 10b, the typical last spring frost is frost-free and the first fall frost is frost-free. Here is when to plant black-eyed susan against those dates.

Your area is effectively frost-free, so frost-anchored timing does not apply. Plant by soil temperature and season instead; see the plant guide.
