The term "bulb" has come to include a variety of plants with a large storage root (or stem) from which the plant grows every year. Whether true bulbs, corms, tubers, or rhizomes, these miracles of nature require only moisture and rising temperatures to end their dormancy and begin to grow. That means bulbs generally are easy and foolproof garden plants. Most are shipped bareroot, at the right time for planting. We include complete planting and growing instructions with every order.
