Peruvian Lily Care

Growing Peruvian Lilies

Peruvian Lilies are flowering perennial plants native to South America, although they grow worldwide. The flowers and foliage look very similar to lilies, but Peruvian Lilies or Alstroemeria are not true lilies. The flowers feature bold hues with dark flecks near the center and bloom from spring through fall for a long-lasting display. Depending on the variety, Peruvian Lilies stand 1 to 3 feet tall. This plant is a perennial in zones 7 through 10.

Planting Peruvian Lilies

Peruvian Lilies grow best in areas that receive full sun in the morning and shade in the afternoon. Plant them in rich soil that is moist but well drained. Plant Peruvian Lilies in the spring after there is no longer a chance of frost, or in the fall before the weather turns cold. Peruvian Lilies grow from rhizomes or thick tuber-like roots. The rhizomes do not like to be disturbed, so give this plant space to allow the root system to fill in. 

Watering Peruvian Lilies

Water Peruvian Lilies with about one inch of water per week or when the soil feels dry. These plants appreciate damp conditions but do not like to be soggy, so avoid overwatering. Plants grown in a very sunny spot will dry out and need water more often than those in part sun.

Fertilizing Peruvian Lilies

Rich soil with high organic content will support new growth and blooms. Fertilize Peruvian Lilies to further support growth and help these plants thrive. Feed these beauties using a balanced plant food, with a ratio of 10-10-10 or something similar. Apply fertilizer in the spring and continue to feed Peruvian Lilies throughout the growing season.

Pruning Peruvian Lilies

Peruvian Lilies do not require pruning but respond to well-timed trims. Deadhead the plant to clean up the appearance and encourage more blooms. If this plant becomes overgrown or leggy, trim it back to promote a more full and bushy appearance.

Caring For Peruvian Lilies in Pots

Container-grown plants can handle more flexible placement options and can be grown in areas outside their hardiness zones. Select a pot with drainage holes so the soil does not become soggy. Potted plants need water more often because the soil dries out more quickly than for plants in the ground. Feel the soil and water when the top layer is dry. Fertilize container plants to replenish the nutrients in the soil.

Winter Care for Peruvian Lilies

Minimal winter care is needed for Peruvian Lilies. Leave the growth in place and remove dead or damaged growth as needed in the spring. Potted Peruvian Lilies should be moved to a protected area. This plant needs a dormant period and will not grow as a houseplant, so relocate the container to a garage, shed, or basement.
