Description
Allium rosenbachianum is a tall species with stems often exceeding 1m (3ft) in height, topped with bright pinkish-mauve flowers, arranged in umbels of approximately 10cm (4in) in diameter.
These bulbous plants have excellent longevity and should be considered as entire perennial plants. They are essential, just like grasses, in flower beds or rock gardens for the light and transparent effect they bring.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
