Description Allium ‘Bubble Bath’ Allium ‘Bubble Bath’ is a charming ornamental onion that produces delightful spherical flowerheads in soft lilac-pink tones. This compact herbaceous perennial typically reaches heights of 30-40 centimetres, making it perfect for front-of-border plantings or container displays. The globe-shaped umbels, measuring approximately 5-7 centimetres across, appear in late spring to early summer atop sturdy stems above neat clumps of narrow, greyish-green foliage. In UK gardens, ‘Bubble Bath’ thrives in well-drained soil in full sun to partial shade. This clump-forming perennial can be planted in spring or autumn, with plants spaced 20-30 centimetres apart. It tolerates drought once established but benefits from regular watering during the growing season. After flowering, allow the foliage to die back naturally, or divide established clumps every few years to maintain vigour. This versatile allium works beautifully in mixed borders, rock gardens, or cottage-style plantings. It combines wonderfully with late spring perennials and provides excellent cut flowers. The attractive seedheads also offer structural interest well into winter, making it valuable for year-round garden appeal.
