Allium atropurpureum

Plant details

Allium atropurpureum is a fun drumstick allium, bearing a tightly packed ball of maroon-purple flowers on top of a tall, stout stem. It's native to the Balkans, where it can be found growing in dry, open spaces.

For best results, grow Allium atropurpureum in a sunny, sheltered spot in free-draining soil. It's ideal for using to fill gaps in a sunny border and may also be grown in pots. Grow in clumps or bold drifts, for the most dramatic displays, and leave the seedheads standing throughout autumn and winter to add structural interest to the garden. Allium atropurpureum makes an excellent cut flower.
