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
With a swish of her silken skirts, Iris sibirica 'Yellowtail' will flounce into your summer borders with true style and aplomb. The gorgeously ruffled, semi-double blooms feature primrose yellow outer falls which encircle the central frosted white flags—a truly sublime combination of mouthwatering fondant fancy shades! Flowering abundantly throughout late spring and early summer, this winsome Siberian iris will naturalise well, forming tall, elegant clumps over time, bringing structure as well as a little light-hearted fun to any display.
Delicate appearance notwithstanding, Iris sibirica 'Yellowtail' is as robust as they come—fully hardy, and with stiff, swordlike foliage that will stand up to wind and rain in even the most exposed locations. Favouring a moist but free-draining soil, but with some drought resistance once established, this unfussy, low maintenance delight is a gleaming highlight in which you can look forward to seeing year after year in your perennial planting scheme.

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.
