A sport of A. rosenbachianum exclusive to ourselves, with large white flowers. A welcome addition to the range of white Alliums with strong stems (there are still very few). Clean stemmed and still in leaf when they start to flower. No-one else will have them so get your order in quickly! May flowering; 30” (75cm)
Planting instructions
Plant 4" (10cm) deep in a well drained position, in a rockery or the front of the border.
