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
Indulge in a truly delectable treat, in the form of dinnerplate Iris ensata 'Tiramisu'. It isn’t edible but it’s certainly sweet on the eye! The huge blooms can reach up to 15cm in diameter, formed of icy white petals which are edged and dusted with a sprinkling of purple. This Iris dishes up the most amazing blooms in early summer, the wide arching petals curve outwards to reveal such spectacular detail. Iris ensata 'Tiramisu' is a head-turning and satisfyingly low-maintenance focal point for areas of the garden with damp soil.
Dinnerplate Iris are the latest development among Iris ensata cultivars, boasting colossal blooms of almost twice the size of traditional varieties—a tempting choice for summer bouquets! Iris ensata 'Tiramisu' is a hardy perennial that forms a dense grassy clump of upright, sword-like leaves and will bloom every year when it’s happy in its place. Commonly called Japanese water iris, these moisture loving plants flourish in damp soils and are even happy when paddling in the boggy soil at the outer edges of a small pond.

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.
