Family

Liliaceae

Botanical Name

ALSTROEMERIA ligtu

Plant Common Name

Lily-of-the-Incas, Peruvian-lily

General Description

In summer this tuberous, tender perennial blooms with a profusion of colorful, lily-like flowers. Lily-of-the-Incas is native to central Chile and Argentina and has slender, sparse, strap-like leaves and tall flower stems. The semi-evergreen leaves are light green with hints of gray. As the summer temperatures rise, the tall stems become topped with branched clusters of trumpet-shaped flowers. These may be orange-red with yellow and dark-red markings or lavender-pink with purple and maroon markings, depending on the subspecies.

Grow lily-of-the-Incas in a sandy soil that is moist and high in organic matter. Non-alkaline soils are best. It may be grown in a mixed border or cutting garden in areas that only get an occasional light frost in winter. Elsewhere grow them in summer as tender perennials. The tubers should be dug and stored in a cool dry place indoors over the winter. The flowers are wonderfully long-lasting when cut.

Many attractive hybrids have been developed from crosses between this species and Alstroemeria haemantha. These are called the Ligtu hybrids.
