Unpack bare roots or rhizomes on arrival and plant them within a week. Until then, keep them somewhere cool and ensure the roots remain slightly moist, never wet.
'Summer Storm'
rose mallow
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.

Plant calendar
Remove the packaging straight away, check the compost and water thoroughly if dry. Check the plant’s hardiness before placing it outdoors. Plant into a border or permanent container within a month, choosing the position recommended for the variety. Keep the top of the root ball level with the surrounding soil, firm gently and water well.
Soak the roots in water for three to six hours immediately before planting. Keep any crown, buds or emerging shoots above the water where possible.
Pot most bare roots into 15–20cm pots filled with peat-free multipurpose compost. Large or depth-sensitive roots, including peonies, are often best planted directly into borders.
Arrange the roots naturally without bending them. Cover the roots completely, positioning the crown and buds at the depth recommended for that particular perennial.
Keep pots in a sheltered outdoor position and water whenever the compost begins to dry. Grow on until roots hold the compost together when lifted from the pot.
Plant into a suitable border or permanent container once well rooted. Add a label and water regularly throughout the first growing season while the perennial establishes.
