• Botanical highlights: Alliums are perennial bulbs from the onion family (Amaryllidaceae), prized for their spherical blooms and striking presence from late spring into early summer.
• Mature size: Expect impressive heights up to 90cm (36") with a spread of 10cm (4"), perfect for adding height and texture among shrubs or as a patio feature.
• Biodiversity boost: These nectar-rich flowers attract bees and other pollinators, making them a smart choice for wildlife-friendly gardens.

Growing Guide & Care

• Planting time: Set bulbs in autumn (September–November) before the ground freezes.
• Location: Choose a sunny spot with well-drained soil; alliums dislike waterlogged conditions.
• Soil preference: Tolerates most soils but prefers neutral to slightly alkaline pH (6.5–7.5).
• Cultivation: Plant bulbs at three times their depth and space about 10–15cm apart.
• Caring tips: Water after planting, then only during prolonged dry spells; alliums are drought-tolerant once established. Deadhead spent blooms to keep beds tidy or leave seed heads for winter structure.
• Hardiness: Fully hardy in UK gardens (USDA zones 4–8).

Design Ideas & Companion Plants

• Create impact: Drift alliums through mixed borders or group in containers for a contemporary look.
• Companion planting: Pair with ornamental grasses, hardy geraniums, or peonies for layered texture and extended flowering interest.
• Cut flowers: Enjoy long-lasting blooms indoors—these varieties are ideal for fresh or dried arrangements.
