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.

Stokesia
'Amethyst'
Stokes' aster
Stokesia 'Amethyst' is every bit as precious as its gemstone namesake, only this treasure blooms rather than sparkles. With upright stems that refuse to flop and an abundance of deep purple flowers, this Stokes' aster has been carefully bred to stand out from the crowd. Each bloom is a ruffled burst of violet-lavender radiance, its intricate detail catching the light in a way that’s bound to draw the eye. Compact yet full of energy, Stokesia 'Amethyst' forms a tidy clump of fresh green foliage, from which its jewel-toned flowers rise proudly in summer, bringing both colour and structure to the border.
The real charm of Stokesia 'Amethyst' lies in its reliability. It produces a generous flush of flowers, each one carried confidently on strong stems that withstand the knocks of wind and weather. Whether planted en masse for a dramatic sweep of purple, or tucked into mixed plantings for a touch of intensity, it plays its part with quiet assurance. And when the blooms are gathered into arrangements, they carry their vibrant hue indoors too, making Stokesia 'Amethyst' as versatile as it is striking. It’s a plant that doesn’t just decorate the garden, but elevates it—adding a touch of gemstone glamour to the everyday.

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.
