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.

Phlox
'Cool Water'
Chill out in summer among Phlox 'Cool Water's sweet array of fragrant pink and white blooms. Plant this dreamy phlox in groups or drifts in borders and look forward to a gentle and relaxing display which will return every year, establishing over time to eventually form a dense clump. Each year this hardy perennial will produce more flowering stems, each one topped with generous flower clusters between July and September. Take a good look at those blooms of Phlox 'Cool Water' and notice their watercolour effect, with dense areas of colour which seems to bleed from one flower into those around it but in a more diluted shade, like the entire cluster is blotted with pink paint.
A display of these is as calming as drifting along a gentle stream! Combine Phlox 'Cool Water' with pastel shades or waves of deep purple, vibrant pink and sparkling white plants to help it make even more of a splash. For best results, start your phlox plant in a temporary pot and grow it on outdoors for a few months before planting it out into a border. This helps it to establish a stronger root system in easy conditions before heading into garden soil, which can be more challenging. Phlox paniculata 'Cool Water' prefers a sunny or partially shaded site in a moist, but free-draining soil. Growing to around 1m tall, it’s sure to make a fabulous focal point.

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.
