Plant allium bulbs from September to December. If needed, keep them in their open packets somewhere cool, dry and well ventilated until planting.
'Miami'
Allium 'Miami' makes a confident statement in the early summer border, rising tall with its rich, deep purplish-red flower heads held aloft on sturdy stems. Each semi-rounded bloom is densely packed with star-like florets, creating a richly coloured effect that feels both bold and refined. There is a natural drama to Allium 'Miami', yet it remains pleasingly versatile, bridging the gap between architectural structure and soft movement. As Allium 'Miami' comes into flower, it brings depth and contrast just as surrounding planting begins to gather pace.
Ideal for prairie-style planting and sunny borders, Allium 'Miami' weaves effortlessly among grasses and perennials, its upright form providing rhythm and vertical interest. The blooms of Allium 'Miami' are highly attractive to pollinators, adding a gentle hum of activity to the garden during its flowering period. Despite its striking appearance, Allium 'Miami' is reliably hardy and undemanding, thriving in full sun and well-drained soil. Whether planted in generous drifts or punctuating a mixed border, Allium 'Miami' offers a sense of balance and vitality that feels both naturalistic and thoughtfully composed.

Plant profile
Plant calendar
Choose full sun or partial shade. Improve heavy soil with organic matter and horticultural grit. For containers, use peat-free multipurpose compost with good drainage.
Plant bulbs pointed side upwards, two to three times their own height deep. A slightly flattened side is perfectly normal and nothing to worry about.
Space small bulbs around 5cm apart. Larger bulbs need more room, generally around twice their own width apart, so their foliage and flowers can develop freely.
Water after planting if the soil is dry, then only when needed. After flowering, allow the foliage to die back naturally. Decorative seedheads can remain in place.
