We begin removing full cases out of the coolers mid March to allow bulbs to slowly come up to temperature and mimic spring. Lily bulbs are quickly packaged, and starting with the warmer areas of the West Coast States, begin mailing out orders in early April. Lower Midwest and Eastern Seaboard quickly follow. Gardeners in cold winter climates, or in mountainous areas, are shipped later in April, having been "saved" in our computer system for the later mailing dates. We will ship lily bulbs through the first week of May, if noted on your order under "comments", otherwise we mail out bulbs when they can safely travel through the post office.
