Hardy Bulbs

for the Midwest

Are these bulbs hardy in your garden?

Hymenocallis occidentalis in bloom Hymenocallis occidentalis (Amaryllidaceae) is reported to have ranged north of the Ohio River into southern Illinois, Indiana, and perhaps Ohio. Bulbs are hardy in Indiana. The sword-like gray-green foliage emerges in late spring and may die down in later summer in dry weather. The flowers appear in late summer or autumn. The 6 to 8 brilliant white blooms are up to 7 inches across from petal-tip to petal-tip. The staminal cup is about 2 inches in diameter. The scape (bloom stalk) is 18 inches to 3 feet in height. The species is said to prefer moist areas in partial shade.

I would appreciate hearing from you if you grow this or related species in a northern climate. Jim Shields,

Hippeastrum x-johnsonii is said to be quite hardy in cold climates. Have you grown it successfully outdoors, in the ground, in a colder climate (i.e. USDA zone 7 or colder)? If so, we want to hear from you. E-mail to Jim Shields, <>
