Delivered to you from September
A superb stately punctuation plant, with densely filled heads of warm purple flowers the size of a grapefruit atop of each tall bare stem. A central Asian species requiring well-drained soils and a sunny site, by the time that they flower the leaves have mostly withered away. Its name is a reference to its impressive height rather than to an enormous flower. A soft seed head remains after flowering.
Plant Allium giganteum bulbs 4-5" (10-12cm) deep to aid stability 8-10" (20-30cm) apart, in a sunny spot with well drained soil where the withering leaves will be camouflaged by other plants in early summer.
Flowers Late June/July
Height 48+" (120+cm)
