How to Grow Pineapple Lily
Eucomis comosa
Eucomis (Pineapple Lily) is a half-hardy bulbous perennial grown for its dramatic late-summer flower spikes topped by a pineapple-like crown of bracts. Plant bulbs in spring in full sun and well-drained soil. Water moderately during growth and feed every 2–3 weeks. After flowering, allow foliage to die back naturally. In cold climates, lift bulbs in autumn and store frost-free; in milder gardens, mulch heavily and leave in the ground.
Yearly Lifecycle
Care Essentials
Feed with a balanced liquid fertiliser every 2–3 weeks during the growing season once shoots emerge.
Watch For
- Vine weevil
- Mealybug
- Bulb rot in waterlogged soil
Companions
Agapanthus, Crocosmia, Kniphofia, Grasses
Care Requirements
Light
Full sun
Needs a warm, sheltered position in full sun for at least 6 hours a day. A south-facing border or container against a wall is ideal.
Watering
Moderate; reduce as leaves die back
Water moderately throughout the growing season. Avoid waterlogging, which causes bulb rot. Reduce watering once foliage starts to yellow in autumn.
Fertilizing
Balanced liquid feed every 2–3 weeks
Apply a balanced liquid fertiliser every 2–3 weeks from when shoots emerge until flowering finishes. A tomato-type or seaweed feed works well.
Pruning
Remove spent flower spikes; cut back dead foliage
Deadhead or cut spent flower stems at the base after blooming. Allow foliage to die back naturally in autumn before cutting it away.
Spacing
30 cm apart
Plant bulbs 30 cm apart and 10–15 cm deep. This allows clumps to develop and spread over time without immediate overcrowding.
Support
Generally not needed
Flower stems are sturdy and rarely need staking except in very exposed, windy positions where a short cane may help.
Growing Tips
Plant bulbs in spring
Plant bulbs 10–15 cm deep in a warm, sheltered spot with full sun and free-draining soil after the risk of frost has passed.
Water during dry spells
Keep the soil moderately moist during the growing season, especially during flowering. Reduce watering as foliage yellows.
Lift or mulch for winter
In cold gardens, lift bulbs after foliage dies back, dry for a week, and store in dry compost. In frost-free areas, mulch 10–15 cm deep.
