We ship February — October.

Or we will send at the proper time for planting:

Winter and Early Spring Orders:
We will send at the appropriate time for Spring planting in your area. See the chart below for approximate starting shipping dates by zone.

Late Spring and Summer Orders :
After shipping has started to your area, we will send as soon as possible, normally within one to two weeks.
PLEASE NOTE – We will do our best to ship as quickly as possible, but the plants are growing in the ground, not sitting on a shelf, so it takes some time to get them dug and ready to ship.

Fall Orders:
We will send as soon as possible, up until it is too late to plant in your area. Orders placed after that time will ship the following spring. See the chart below for last shipping date by zone.
