Alstroemeria, also called the Peruvian lily, is a stunning perennial plant native to South America.
Known for its colorful blooms in red, orange, purple, pink, yellow, and white, this plant is a favorite for gardens and cut flower arrangements. Follow this guide to plant, grow, and care for Alstroemeria effectively.
Ideal Growing Conditions for Alstroemeria
To thrive, Alstroemeria requires a sunny location with fertile, well-drained soil enriched with organic matter. Plant them in spring to allow them time to settle before flowering. These hardy perennials can return year after year, although their growth dies back to the ground during winter.
Alstroemeria looks stunning in garden borders, paired with other perennials and shrubs. It also grows well in pots, making it a versatile choice. For garden beds, space plants about 60 cm apart to ensure they have room to grow.
Caring for Alstroemeria: Watering and Feeding
Proper watering is crucial for Alstroemeria. Water newly planted specimens during dry spells until they establish, but avoid over-watering to prevent root rot. In pots, keep the compost evenly moist, and during hot weather, give border plants an occasional thorough soak to boost flowering.
Feed the plants with a high potash fertilizer (like liquid tomato feed) during summer to encourage vibrant blooms. Taller varieties benefit from staking to support heavy flower-laden stems.
Pruning and Deadheading Alstroemeria
For continuous blooming, deadhead the plants as flowers fade. Instead of trimming just the flower heads, pull the entire stem gently from the base. This stimulates fresh growth and ensures a longer flowering season.
Harvesting Alstroemeria for Arrangements
Alstroemeria is ideal for cut flower arrangements as its blooms last for weeks in a vase. Harvest stems by pulling them from the base and trimming them to fit the vase. Refresh the vase water every few days to keep flowers fresh.

Propagating Alstroemeria
Alstroemeria forms clumps of roots over time, which can be divided every few years to rejuvenate the plant and produce new specimens. Divide the clumps in early spring, being careful with the fleshy tuber-like roots, which are delicate. Replant divided clumps immediately into enriched soil.
Common Problems with Alstroemeria
While generally low-maintenance, Alstroemeria can face issues with excess winter wetness, which may cause root rot. Ensure plants in borders are in free-draining soil, and protect potted plants from heavy rain by moving them to sheltered areas or laying them on their sides when dormant.
Young spring growth may attract slugs and snails. Protect plants with eco-friendly barriers or bait if necessary.
