allium ‘Summer Beauty’

Allium lusitanicum¬†Summer Beauty‘ (syn. A. angulosumSummer Beauty‘) is often appreciated for its glossy deep green foliage in the spring and lilac flowers in the summer. Allium ‘Summer Beauty’ can also add tremendous color and texture to the winter garden.

Allium ‘Summer Beauty’ produces leaves up to 10 in. long with flowering stems of up to 20 in. tall. These plants work well in mass plantings, although individual plants can be slow to establish and take up to three years to begin spreading. ‘Summer Beauty‘ is a sterile cultivar, so unwanted spread by seed-in is not a concern. Allium ‘Summer Beauty’¬†is native of central Europe to northern Asia–from France and Italy to Siberia and Kazakhstan–is at home in the Midwestern perennial garden.

Roy Diblik of Northwind Perennial Farm developed A. ‘Summer Beauty‘ based on plant material collected from a Chicago area garden. The cultivar is now widely planted throughout the Midwest and Northeastern regions due, primarily, to its resiliency to diseases and pests and, additionally, to its great value as a source of pollen and nectar for honeybees, bumble bees, native bees, and butterflies.
