When to Plant
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.
Deep, velvety red flowers with a sheen in the throat. They are accented by golden anthers, a white stigma, and a touch of white at the points of the petals. “Magnum” means “great” in Latin and is at the root of such words as magnanimous, magnitude, and magnificent. Yes, yes, and yes!
Allow 12 weeks from potting to bloom. Most bulbs will not flower until after Christmas.
Amaryllises are not available for shipment until mid-October. If you are also ordering outdoor bulbs and need the outdoor bulbs earlier, please place two separate orders.
Bulb size is determined by the circumference around the largest part of the bulb. Colorblends only delivers top size bulbs. Large bulbs produce more or larger flowers than small bulbs.
Hardy in USDA zones 8b to 10b in the South or 10b on the West Coast.
Except where winters are very mild, amaryllis bulbs must be grown indoors in containers. Complete growing instructions are provided in our Planting & Care Instructions (PDF). A paper copy of the instructions is enclosed with every order.
In mild-winter areas (see the USDA Zones tab), bulbs can be planted outdoors. They perform best in partial shade and require well-drained soil. They may need irrigation in dry climates. Once established, they typically bloom in the spring.
