When to plant:	Up to 3 weeks before last frost.

Verbena do well in a tiny bit of cold which tells us that you can plant them a bit earlier in the year than more sensitive plants.

The earliest that you can plant verbena in Oakland is March. However, you really should wait until April if you don't want to take any chances.

The last month that you can plant verbena and expect a good harvest is probably August. You probably don't want to wait any later than that or else your verbena may not have a chance to really do well. If you are starting your verbena indoors then you might be able to get away with starting them a little bit earlier.
