This quite unique, summer-flowering plant has straight, slender stems, topped by egg-shaped flower heads as opposed to the usual conical sphere, that start off completely chartreuse-green before turning maroon-claret at the tip and finally becoming overall deep reddish purple. Flowering begins in of July, much later than most purple and lavender alliums and last for many weeks.
Sow seeds at any time covering them with compost or grit 5mm deep, keeping the seed pot in a cool, well-lit spot outdoors. Artificial heat is not needed and can prevent germination so be very patient as many species will only germinate in the spring after chilling or freezing in the moist seed tray in the winter. Grow on individual seedlings in small pots until of sufficient size to be potted on or planted out into the open ground.
