Pineapple Lily
Eucomis · Asparagaceae
The pineapple lily is a small exotic for terrace and border: its flower spike, densely set with starry florets, carries a green tuft of leaves on top and looks like a slender pineapple. It flowers for weeks at the height of summer and is surprisingly undemanding. We stock Eucomis as a container plant in nursery quality — strong bulbs that come back year after year.
- Light
- Full sun; in partial shade the flower spikes grow soft and tend to flop.
- Watering
- Water regularly and thoroughly in summer; keep almost dry in winter.
- Care level
- Easy
- Botanical
- Eucomis
Three groups dominate the trade: Eucomis bicolor with purple-edged green-white florets, Eucomis comosa with cultivars such as the dark-leaved ‚Sparkling Burgundy‘, and the compact Eucomis autumnalis. For window boxes there are now dwarf cultivars barely thirty centimetres tall.
The pineapple lily is a summer-growing bulb: it sprouts late, often not before May, flowers from July to September and dies back in autumn. If your pot looks empty in spring, do not throw it out too soon — the bulb simply needs warmth to get going.
It is happiest in full sun in rich, free-draining soil. In a container that means good potting compost with some sand, a drainage hole, and regular watering and feeding during the growing season. The more sun it gets, the sturdier the flower spikes stay and the deeper the red-leaved cultivars colour up.
The most common mistake is a wet winter. The bulbs are only borderline frost-hardy and rot in cold, wet soil; in the Rhineland containers are best overwintered dry and frost-free at five to ten degrees, while in the border a dry, sheltered spot with a thick mulch layer helps. Normal watering resumes in spring.
The pineapple lily stays attractive after flowering too: the seed heads keep their pineapple silhouette into autumn and add wonderful structure to late-summer plantings next to grasses and dahlias. Individual cut spikes last remarkably long in the vase and are a real eye-catcher.
Is Pineapple Lily toxic to children and pets?
- Children
- Mildly irritating
- Cats

- Dogs
- Mildly irritating
There is little solid data on the toxicity of the pineapple lily; the bulbs contain compounds used in South African traditional medicine. To be safe we class it as mildly irritating — do not eat bulbs or plant parts and keep them away from pets.
Typical symptoms: Eating larger amounts may cause gastrointestinal upset such as nausea, vomiting and diarrhoea.

Overview: toxic & non-toxic plants for cats, dogs and children
Care
- 01Choose a fully sunny, warm spot — the more sun, the more compact and colourful the plant.
- 02Plant in free-draining, rich soil; make sure containers have a drainage hole.
- 03Water regularly and feed every two weeks during growth and flowering.
- 04Expect a late start: the bulb often sprouts only in May — do not discard it too soon.
- 05Stop watering in autumn and overwinter containers dry and frost-free at five to ten degrees.
- 06Leave the seed heads standing — they decorate the planting well into autumn.
Frequently asked
- Is the pineapple lily hardy?
- Only to a degree. Eucomis tolerates light frost but quickly rots in cold, wet soil. Overwintering dry and frost-free at five to ten degrees is the safe option; in the mild Rhineland it can stay in a sheltered border spot with a thick mulch layer and rain protection.
- Why does my pineapple lily sprout so late?
- That is completely normal: Eucomis is a summer-growing bulb from South Africa and needs soil warmth to get started. Shoots often appear only in May, sometimes not until early June. Be patient and only then resume regular watering.
- Is the pineapple lily toxic to cats and dogs?
- It is not considered strongly toxic, but neither is it proven safe. The bulb in particular contains compounds that can cause gastrointestinal upset. We recommend keeping it out of reach of pets and seeking veterinary advice if you suspect ingestion.
- How do I get the pineapple lily to flower every year?
- Three things matter: full sun, regular feeding through summer and a dry winter rest. Store the bulb dry in autumn, then grow it warm, sunny and well fed from May onward, and it will reliably produce its pineapple bloom every year.
