A large-scaled perennial border in which ornamental onions (Allium schubertii) play a starring role, even (or perhaps especially) after their flowering period. This is because after flowering, certain ornamental onions such as this Allium schubertii – but also Allium christophii, A. atropurpureum, A. multibulbosum and A. 'Globemaster' – turn into conspicuous dried flowers that often provide more ornamental value than their original flowers.

This border has a pattern of diagonal bands composed of ornamental onions, perennials and ornamental grasses. The plant palette is limited but this is no problem since not only the bulb plants but also the perennials (Echinacea purpurea 'Magnus' and Echinacea pallida) and ornamental grasses remain decorative after flowering and long into the autumn.

Alliums are classified as spring-flowering bulbs because they are planted before the winter (preferably in October/November). They prefer a location with good drainage and, in this case in particular, full sun. In this planting, about 12 bulbs of Allium schubertii were planted per square metre (14 bulbs per square yard). Their peak flowering period occurs in May.
