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
Phlox amplifolia 'Goliath' is a hardy, tall Phlox—and is a slightly shorter companion to 'Hercules'. It produces tall clusters of wonderfully fragrant violet-purple blooms, each with a white eye, that add height, colour and immediate joy to any summer garden. These flower clusters are fully twice the size of traditional tall Phlox cultivars. The individual blooms are fragrant, while the stems are conveniently strong enough to support the heavy clusters. The densely-packed, lance-shaped leaves are compact, and deep green with prominent veins.
Given as much sun as possible, this Phlox will quickly become a favourite, as its blooms last and last. Phlox amplifolia 'Goliath' is extremely easy to grow, and is resistant to mildew, which can be a problem with some forms of Phlox. It is lovely on its own, or its colour pairs well with other summer-flowering perennials, such as the yellow rudbeckias or pink echinaceas. The flowers will be visited by pollinating insects, and once cut, will last a long time in water.

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.
