Hardy in USDA zones 4a to 7b in the South or 10b on the West Coast.

Drumstick allium. The last of the bulbous alliums to bloom. Its egg-shaped, wine-red flowerheads wait until summer to color up. Puts on a nice show when planted in tight groups in a perennial border, and the bees do love it.
Deer Resistant

Note: Alliums are resistant to deer, but rodents such as voles and gophers may eat the bulbs.

Bloom times are relative within the spring bulb season, which varies from place to place and year to year. They are intended to help you plan a sequence of bloom from Very Early season to Very Late season. About two weeks separate Early from Mid and Mid from Late. The start and duration of bloom is heavily dependent on the weather. Warm temperatures speed up growth and flowering; cold temperatures slow them down.

Delivery & Planting Times

Spring-flowering bulbs must be planted in the fall. They need cool soil to make roots before the onset of winter. Cool fall weather arrives at different times from north to south and from high elevations to low.

Please note that the temperature of the soil lags behind the air temperature. You can generally plant later than the windows provided in this map. As long as the ground is not frozen, you can still plant.

The amaryllis are the last bulbs to arrive in the Colorblends warehouse. They are typically available for delivery toward the end of October. They can be planted upon receipt. They can also be stored in a cool, dry location for several weeks. Please note: Amaryllis bulbs may start growing before they are potted. If you decide to delay planting, open the bag(s) and set the bulbs on their roots so that the flower stems can grow straight up. And don't forget to mark your calendar or set a reminder to pot the bulbs.

Paperwhites can be potted upon receipt. They can also be stored in a cool, dry location for many weeks. Many people pot their bulbs in batches, one after the next, to keep the fragrance coming. It's not unusual for paperwhites to begin to sprout while in storage. The shoots emerge an inch or two and then stop, as though the bulbs realize they are getting ahead of themselves. The shoots often curl around the bulbs, pointing opposite gravity. After the bulbs are potted, the shoots straighten up.
