Alstroemeria Hybrida


Deciduous types. For many years, deciduous alstroemerias were the only ones readily available as garden subjects. The seed-grown Ligtu hybrids and Dr. Salter’s hybrids have azalea-like flowers in beautiful, edible-sounding colors— orange, peach, shrimp, salmon— as well as red and near-white; all types are flecked and striped with deeper colors.

Evergreen. These include series such as Meyer, Cordu, Premier, and Inca. They vary in height and come in many colors, mostly in the purple–pink–red range with dark flecks. Usually sold by color; buy in bloom. New hybrids show up constantly, some root-hardy to 0°F/–18°C. Check with local nurseries for availability.
They produce leafy shoots 2–5 ft. tall in late winter and into spring; as these shoots begin to brown, the flowering shoots appear, with blooms following in early to midsummer. If allowed to set seed, they will self-sow. Plants go dormant after bloom and need no water unless winter rains fail. They naturalize where winters are not severe. Sow seeds in fall,winter, or earliest spring, either where plants are to grow or in pots for later planting out.
