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.
Once you have Ascelpias 'Soulmate' in your garden you’ll treasure it forever, just like a best friend! This lovely form of the American wildflower known as swamp milkweed has so much going for it. For starters, it attracts all kinds of butterflies, bees and beneficial insects to the garden, who flock to it all summer long to sip its potent nectar. It’s also a lovely addition to borders, wildflower meadows and pond areas, forming a good-sized clump with attractive, linear deep-green leaves and very pretty clusters of flowers, each one an intricate work of miniature deep rose-pink petals with a soft pinkish white heart. On top of that, the blooms of Ascelpias 'Soulmate' smell divinely sweet, giving off notes of vanilla in the summer breeze. Growing up to around 60cm tall, the long stems and lasting flower power makes it a fantastic cut flower too, so why not bring the fragrance indoors?
The great thing about swamp milkweed is that it’s very adaptable and resilient, making it easy to grow and trouble-free once established. You can plant Ascelpias incarnata 'Soulmate' in wetter areas of the garden or in clay soils, as the swampy element of its common name indicates, but it’s equally happy in ordinary free-draining garden soils. Before planting into more challenging soil types, it’s a good idea to give Ascelpias 'Soulmate' a gentle start in temporary pots to grow on for a few months before planting out into the garden. You can grow it in groups in a border, where it looks great with other summer flowering perennials such as Monarda, Echinacea and maybe even a butterfly bush (Buddleja) and some scabious to create a nectar-bar for the insects.

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.
