This is my favorite Amaryllis that I have grown so far. I potted the bulb up on 10/28, and it started blooming on 12/27. The bulb sat doing nothing for many weeks, then suddenly 2 bloom stalks started growing, with no foliage. The bloom stalks are 22 inches tall, and the flowers are 6 inches wide. All 4 flowers on the bloom stalk bloomed within 2 days, creating a beautiful display. The stalks did not need staking. I would gladly buy this variety again.

Very tall plant with large flowers in a deep red velvet. I bought a large bulb which was already potted with 1-inch foliage on 10/28. The plant bloomed on Dec 25. The foliage and bloom stalk grew to 29 inches tall. I got two stalks with 4 flowers each. Flowers are 7 inches across. For me this amaryllis is too tall, and the flowers are so big and heavy the whole pot fell over repeatedly. As beautiful as it is, I would not buy this one again.

Have had this one since the 1990's. It originally came mail order from either Park's or its then sister company, Wayside. This is the easiest one to force that I have and always blooms first. The flowers are large; around 8 inches across. But in all the time I've had it, there have never been more than 2 blooms per flower stalk. The bulb multiplies vigorously by offsets.

Lycoris squamigera and Amaryllis belladonna can be easily confused. L. squamigera has a green inflorescence stalk, versus a dark stalk on A. Belladonna.

I've grown mine 5 years and it skipped blooming last year, but had 5" flowers this spring, so no complaints.
