General Description
Differing in form from most other double "amaryllis", this 1993 introduction has disheveled salmon-orange and creamy white blooms with numerous often misshapen "petals." Don't let the common name fool you: like most so-called "amaryllis," this tender perennial bulb is a hybrid of the South American Hippeastrum rather than the South African Amaryllis.
The dark to medium green strap-like leaves grow from a large bulb and are nearly evergreen in moist frost-free climates. The somewhat up-facing to horizontal blooms are borne atop stout, leafless, nearly knee-high stems (scapes) in four-flowered clusters. Mature bulbs produce multiple scapes. Blooming usually occurs in spring or summer, though purchased bulbs are conditioned to flower in winter.
Hybrid Hippeastrum bulbs are easily obtained in late summer and fall from mail-order bulb catalogs and garden centers. If grown in a sunny window and provided average moisture, they will flower within weeks of planting but may flower at other seasons in subsequent years. Containerized bulbs should be planted in a porous, moderately fertile potting mix with their "shoulders" exposed. This variety is prone to bulb rot if not given perfect drainage. Giving potted bulbs a dry rest in late summer will encourage winter bloom. Repot the bulbs only when their vigor wanes. Hippeastrum are great garden plants in frost-free climates. They thrive in full to partial sun and well-drained, humus-rich soil. Although usually planted near the soil's surface, they can also be planted a bit deeper, especially where light frost may occur. Watch for streaked or stunted leaves with white spots, which may signal the presence of a viral disease or mealybugs.
Grow these bold bulbs in tropical beds and planters or as beautiful holiday potted plants for table displays.
