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.
Out of season
Hosta 'Devon Green' is a chance sport of Hosta 'Halcyon', one of the most popular hostas of all time. It forms a dense, medium-sized hummock of heart-shaped leaves. Each leaf is a warm, dark green with a highly glossy surface. This shows in perfect relief its distinctive and prominent veining – the real attraction of this cultivar. And the thickness of the leaves makes 'Devon Green' one of the best varieties for slug resistance. In high summer, lily-like flowers of pale lilac shades are held on tall spikes.
Hostas, or plantain lilies, are almost exclusively shade-lovers, and grown for their large, lustrous foliage. They can be used as ground cover in a border, or as underplantings for shrubs and trees. Or, if you have just a small courtyard, patio garden or balcony, they make handsome specimens to grace a patio pot.
One of the 'Devon' Series of hostas, Hosta 'Devon Green' has received an Award of Garden Merit from the Royal Horticultural Society (RHS).

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.
