Why choose white alliums?
A white allium looks lighter than the familiar purple ornamental onion, so it fits easily into modern borders, country gardens and planting schemes with soft colours. Anyone searching for white allium, white ornamental onion or white allium bulbs is usually looking for a plant with a strong shape that still feels calm. That is exactly what makes white alliums so versatile. For serene pairings, combine them with white tulips or extend the season with early white daffodils.
Which white allium suits your garden?
White alliums come in several different looks. Some varieties produce large round flower heads, while others bloom in a looser, more natural way. If you are searching for Allium nigrum or white allium 'Mount Everest', for example, the main difference is often the overall look. So choose above all by effect: bold and structured, or airy among perennials. Planting in containers or on a balcony? Discover Alliums for pots.
White alliums: planting and care
Plant white allium bulbs in autumn, from September to November. Preferably give them a sunny spot in well-drained soil. For the best result, plant white ornamental onions in groups so the flowers make more impact together. After flowering, let the foliage die back naturally so the bulb can store energy for the next season. For detailed tips, see Allium planting and care.
