Southern England - detail & sources
Neither source gives region-specific UK dates; RHS gives a UK-wide hardiness rating (H6, hardy in all of the UK) with no frost-chasing urgency described for this hardy perennial, so one window is applied across all four sub-regions rather than inventing a north/south gradient the sources do not support.

Soil & Growing Conditions
Water: moist but well-drained or well-drained (RHS); dry summers, wet mild winters preferred (Gardener's Path)
Growth Stages
| Stage | BBCH | Notes |
|---|---|---|
| Propagation | 0 | Sow seed in containers in a cold frame when just ripe or in spring, or divide established clumps in spring (RHS). |
| Establishment | 3 | Low-growing, clump-forming bulb with narrow, strap-shaped grey-green basal leaves; full sun, well-drained soil (RHS). |
| Flowering | 6 | Summer: bright yellow, upward-facing star-shaped flowers on stems to 25cm tall (RHS). |
| Naturalising / dieback | 9 | Naturalises easily in borders, rockeries and woodland clearings (Gardener's Path); remove old flowered stems and foliage as the only maintenance (RHS). |
Harvest & Storage
When to pick: Grown primarily as an ornamental bulb; leaves and bulbs are edible but the plant is chiefly valued for its bright yellow star-shaped summer flowers and its ease of naturalising in borders, rockeries and woodland clearings (Gardener's Path).

A secondary gardening reference rather than a university or horticultural authority, used only for native range/naturalizing context RHS does not cover, not contradicted by any higher authority. Allium moly, also called golden garlic or lily leek, is native to a range stretching from eastern Spain to Italy and parts of North Africa. Low-growing and clump-forming, it adapts well to borders, rockeries and woodland clearings, where it naturalises easily. Thrives in a Mediterranean-type climate of dry, hot summers and wet, mild winters.

Hardiness H6 (hardy in all of UK and northern Europe, -20 to -15°C). Full sun; south or west-facing aspect. Soil: chalk, loam or sand; moist but well-drained or well-drained; pH acid/alkaline/neutral. Height 0.1-0.5m, spread 0.1-0.5m. Time to maturity 1-2 years. Narrow, strap-shaped grey-green basal leaves; bright yellow, upward-facing star-shaped flowers on stems to 25cm tall during summer. Propagate by seed sown in containers in a cold frame when just ripe or in spring, or by division of clumps in spring. Grow in full sun with fertile, well-drained soil; container growing recommended for heavy clay soils prone to winter saturation. PESTS: susceptible to allium leaf miner and onion fly. DISEASES: may develop onion white rot and onion downy mildew -- named directly for this species, not inferred. Maintenance: remove old flowered stems and foliage only.

How this guide is put together
The growing data on this page — sowing windows, pests, diseases, soil and site requirements — comes from named horticultural sources, listed in References below, checked against RHS and Met Office guidance. An automated pipeline assembles that verified data into the page you're reading: it selects which facts to lead with and builds the surrounding prose and layout. It does not invent a date, a source or a number — where a verified value for a field isn't available, the page leaves it out rather than guessing. A person reviews and publishes each page; nothing goes live unverified.
