x Amarcrinum memoria-corsii (Crinodonna) - An evergreen bulbous perennial that produces 2 inch wide by two feet long strap-shaped leaves reminiscent of Crinum and lightly-scented, large rose-pink flowers in umbels on 2 foot stalks resembling the flowers of Amaryllis belladonna, although they actually have a narrow curved tube closer to that of a Crinum flower. The flowers are quite fragrant and bloom from spring to summer and sometimes into fall.
Plant in full sun to partial shade and provide moderate irrigation. Evergreen to 20-25 degrees F and cold hardy to around 10 degrees F and useful in USDA Zones 8-10 or even lower with deep mulch. This plant is resistant to predation by deer and rodents.
Amarcrinum bulb is the result of the intergeneric cross between the South African plants Crinum moorei and Amaryllis belladonna. The first written record of this cross, under the name Amaracrinum howardii, was an article by John Coutts in an issue in 1925 of Gardener's Chronicles (3, 78: page 411) where it was noted this bi-generic hybrid raised by Mr. F. Howard of Los Angeles first flowered at the Royal Botanic Garden Kew but it was also noted that the plant had been previously "in cultivation for a good many years". Coutts however noted in this article the mention 4 years prior in the 1921 issue of Gardener's Chronicles (3, 69, page 32) the listing of this same cross that the author, Dr. Attilio Ragionieri of Castello, Italy called Crinodonna memoria corsii and named to honor the Marquis Bardo Corsi Salvati . Coutts noted that , which he thought the bi-generic genus name incorrect since the Amaryllis was the seed parent and it should have been listed first in the new name. The current treatment it to use Coutt's constructed genus name with Ragionieri's specific epithet. Our plants came to us unnamed but appear to be the selection developed by Fred Howard in California in the 1920 that is often named for him.
