Description
There’s a touch of theatrical glamour about Hibiscus 'Summer Storm'—the kind that makes you pause mid-watering can in admiration. This rose mallow is a hardy perennial with a strong, upright habit, forming a handsome bush cloaked in dark purple-red foliage. When late summer arrives, its spectacular, dinner-plate-sized blooms unfurl in soft pink, each marked with a dramatic, star-shaped crimson centre that glows like a sunset through stained glass. Even when not in flower, Hibiscus 'Summer Storm' lends rich contrast to border companions — think silver grasses, pale echinaceas, or creamy phlox — creating a painterly tableau of colour and texture.
As a late-season performer, Hibiscus 'Summer Storm' brings warmth and exuberance to the garden just when many plants begin to fade. Its blossoms draw bees and butterflies in droves, rewarding both gardener and pollinator alike. Despite its exotic looks, it’s wonderfully hardy and surprisingly easy to grow, thriving best in full sun with moisture-retentive soil. Plant Hibiscus 'Summer Storm' where you can admire its extravagant blooms up close, by a terrace, pond, or path, and enjoy its blend of drama and grace year after year.

Useful information
-
Soak the Hibiscus 'Summer Storm' roots in water for 3-6 hours prior to planting
Plant your "Rose mallow" bare roots into temporary pots with a multipurpose compost within a week of delivery and grow-on in a sheltered spot outdoors
Choose a pot which comfortably fits the bare roots. Some have a noticeable crown which should be just below the soil surface with any top growth exposed. Some varieties are a length of root which should be planted lengthways and shallowly (1-2cm deep).
Plant out into borders or permanent containers in late spring or early summer once in full growth. Choose a position in sun or shade depending on the variety.
