Allium stipitatum 'Violet Beauty' - 3 Bulbs - 10/12cm



Allium 'Violet Beauty' Overview

Allium stipitatum 'Violet Beauty' is a late-spring and early summer-flowering, deciduous perennial bulb that produces upright violet-purple rounded heads that can get 10cm across and 80cm high. These flower heads are made of clusters of individual star-shaped flowers. This easy to grow bulb needs to be planted in autumn in soil that doesn't get too wet. Allium 'Violet Beauty's' strappy grey-green leaves will start dying back before its flower head has fully opened - in early summer - making it ideal for planting in amongst grasses or later growing perennials to give a prairie-style feel. The spent flower heads will remain for a long time, showing some winter interest, or they can be cut for floral arrangements. Allium 'Violet Beauty' is part of the Royal Horticultural Society “Plants for Pollinators” initiative to showcase plants that support pollinator populations by providing ample nectar and/or pollen. An excellent choice for encouraging pollinating insect wildlife into your garden! It has also earned an RHS Award of Garden Merit.
