This compact, clump-forming perennial produces soft, lavender-mauve globe-shaped flowerheads on sturdy stems, rising above blue-green, strap-like foliage from late spring through summer.

Allium 'Bubble Bath' thrives in well-drained soil and full sun, making it ideal for borders, containers, and rockeries. Its long-lasting blooms attract bees and butterflies, adding pollinator-friendly appeal to the garden while being naturally resistant to rabbits and deer.

The fine-textured foliage remains from early spring to late autumn, providing lasting interest. Perfect for cut flowers, its delicate, spherical blooms add structure and charm to floral arrangements, extending its impact beyond the garden.

How to care for Allium Bubble Bath:

Alliums thrive in a sunny position with well-drained soil, making it an excellent choice for borders or containers. For potted plants, use a container with good drainage holes and fill it with a free-draining compost mix, such as a blend of multipurpose compost and grit, or loam based compost such as John Innes.

When planting, ensure the root ball sits at the same level as it did in its nursery pot, and water well after planting. Place the container in a sunny spot and water regularly during dry spells, allowing the top layer of compost to dry out between waterings.

Deadhead spent blooms to keep the plant tidy and encourage new flowering stems. Feed with a balanced liquid fertiliser every few weeks during the growing season to promote healthy growth and flowering.

In winter, move containers to a sheltered spot or insulate them to protect the roots from severe or prolonged frost. Every few years, divide the plant in autumn to refresh the compost and maintain its vigour.
