Uses and Benefits: Astrantia 'Sparkle Stars White' is ideal for illuminating darker corners of the garden, weaving light among ferns, hostas, and other shade-loving companions. Its compact form suits smaller beds, path edges, or container plantings, while its extended bloom time makes it a hardworking choice for filling gaps between peak seasons. It is also highly attractive to bees and other pollinators, contributing to garden biodiversity. A staple for cut-flower gardens, its blooms retain their form beautifully in both fresh and dried arrangements.

Companion Plants: Pair Astrantia 'Sparkle Stars White' with Dryopteris 'Brilliance', whose coppery fronds in spring and lush summer texture create a soft, earthy contrast to the astrantia’s cool white blooms. Add Heuchera 'Timeless Treasure', whose silver-veined foliage and soft pink flowers bring depth and movement below the airy stems. Finish the composition with Brunnera 'Jack Frost', whose frosted foliage echoes the astrantia’s delicacy and adds gentle shimmer in the shade. Together, these companions form a subtle, luminous tapestry that evolves gracefully through the seasons.

Care Instructions: Plant in part shade with moist, organically enriched soil. Water regularly, especially in dry conditions or sunnier exposures. Deadhead faded flowers to prolong blooming. Cut back spent foliage in late fall or early spring, and divide clumps every 3–4 years to maintain health and flower production.

History: Astrantia 'Sparkle Stars White' is part of the Sparkle Stars series, bred for compact growth, heavy flowering, and clean, vibrant colours. Derived from Astrantia major, a species native to meadows and woodlands of central and eastern Europe, this cultivar embodies the best of both wild charm and garden refinement. It continues the tradition of astrantias as beloved perennials for naturalistic and formal designs alike.

Final Thoughts: Astrantia 'Sparkle Stars White' is a quiet constellation in the shade—graceful, long-blooming, and richly detailed. When placed among the glowing fronds of Dryopteris 'Brilliance', the sculpted foliage of Heuchera 'Timeless Treasure', and the icy shimmer of Brunnera 'Jack Frost', it becomes part of a cool, calming garden ensemble. A delicate yet durable perennial that brings lasting sparkle to shaded and softly lit spaces.
