Allium ‘Purple Sensation’ bears large, rounded heads of deep violet, star-shaped flowers, on tall sturdy stems. It’s perfect for growing in drifts or large clumps in a sunny border, or large container, and makes an impressive cut flower.
For best results, grow Allium hollandicum ‘Purple Sensation’ in fertile, well-drained soil in full sun. Plant bulbs up to three times their diameter, in autumn. It’s not fully hardy and in colder regions should be mulched, or planted in pots and moved to a frost free area in autumn.
