About

Allium phanerantherum is a clump-forming bulb in the Amaryllidaceae, known by the common name conspicuous-anthered garlic which alludes to its prominent anthers. It produces deciduous leaves and a leafless flowering stalk that appears in late spring to early summer. Flowers are produced between May and July and the plant favours full sun and well‑drained soils.

In the garden

Allium phanerantherum is a bulbous member of the onion genus, native to parts of the eastern Mediterranean and the Near East including Iran, Iraq, Lebanon–Syria, Palestine and Türkiye. It forms discrete clumps from bulbs and carries deciduous foliage before sending up a leafless flowering stem in its May to July season. Plant it in a sunny spot with good drainage; the species tolerates a wide range of soils (chalk, clay, loam or sand) and copes with acid, neutral or alkaline pH. It is rated H6 (very hardy), so it is suitable for outdoor planting across most of the UK and will tolerate both exposed and sheltered positions on south-, west- or east-facing sites. Use these Alliums where their architectural flower stems can be seen: gravel and cottage-style borders, city courtyards and patio containers all suit the clump-forming habit. It also works in wildlife-oriented beds and as a cut flower. Cut stems while in flower between May and July to display the plant’s conspicuous anthers in a vase.
