Care

Exposure

Choose a sunny to semi-shaded location for optimal flowering. Lusitanian Garlic handles direct light well and thrives in open areas. Avoid overly shaded spots that would slow down flowering.

Soil

Plant the bulb in well-drained, light soil, preferably slightly chalky. Overly moist or compact soil causes bulb rot. Enrich the soil with coarse sand if drainage is poor.

Watering

Water moderately when planting and during spring growth. Once established, reduce watering: this species dislikes excess moisture. Let the soil dry out between waterings during summer.

Fertilizer

A light application of balanced fertilizer in spring is plenty. A well-planted bulb doesn't require regular feeding. Instead, focus on good soil preparation at planting time.

Pruning and cleanup

Let the foliage die back naturally after flowering: it replenishes the bulb's reserves. Remove only faded flowers to avoid wasting energy. Clean up dead leaves in autumn.

Diseases and pests

This species is generally robust and rarely troubled by pests. Watch mainly for rot if the soil is too wet or drainage is poor. Good air circulation and dry soil in winter prevent these problems.

Did you know?

Lusitanian Garlic owes its name to Lusitania, the ancient Latin name for the Iberian Peninsula. A member of the garlic and onion family, it produces remarkable flowering in umbels of small pink-lilac to violet flowers, much loved by butterflies and pollinators. Unlike many ornamental garlics, this species remains discreet and hardy, ideal for Mediterranean rockeries.

Where to buy it

Plant the bulbs in autumn for spring flowering. Pick a plant with healthy foliage and roots that are not exposed. Best time: from September to November.
