  • Light needs: Full sun
  • Soil: Well-draining

This resilient perennial flower blooms for months, from summer through fall. Alstroemeria can be planted with other flowers in containers or featured all on its own in a border. It will return year after year when kept in well-draining soil in a sunny location. Deer typically leave it alone.

Consider adding these plants to your cutting garden. The tropical-looking flowers will stay fresh for two weeks or even longer in a vase. For best results, pull (don’t cut) flower stems when they first open.

The vibrant, exotic look of alstroemeria is also super attractive to hummingbirds looking for a colorful source of nectar. In excessively hot or dry conditions, flowering may slow down, but it should pick back up in cooler fall weather. This is a favorite perennial for gardeners in the West, where the plants flower all summer. Fertilize and water your plants regularly, but make sure the soil is not soggy or the tubers could rot.

There are many colors to choose from. The Summer Saint cultivar features bright pink blooms. For vivid yellow and orange flowers, try Indian Summer.
