Flowers of the evergreen hybrids come in shades of purple with dark flecks and last well in bouquets. Alstroemeria aurea blooms come in shades of yellow and orange.

The 2-to 3-foot tall plants produce flowering shoots as long as the soil doesn't get too hot. (Twist the shoot off at the base to keep them coming).
