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
If you like to flaunt the fanciest flowers, it’s time to put dinnerplate Irises like Iris ensata 'Tub Tim Grob' on your plant radar. This is as pink-cream coloured and luxurious as the classic Thai Ruby desert it’s named after. The wide arching petals of Iris ensata 'Tub Tim Grob' are frosted with a tracery of sugary lilac-pink streaks that fade to white at their rippling outer edges. A flicker of gold at the centre of each bloom adds an eye-catching contrast to these over-sized blooms. Dinnerplate Iris are the showgirls of the Iris world boasting enormous blooms, twice the size of traditional Iris ensata varieties. Just a few stems will add instant glamour to summer bouquets!
Iris ensata 'Tub Tim Grob' relishes a spot in sun with cool, damp soil that won’t dry out in summer. Paddling in damp, boggy borders or the outer margins of ponds or any other area with moisture-retentive soil, this Japanese water iris will gradually form dense clump of elegant, slender leaves that dance in the breeze adding height and movement to planting schemes.

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.
