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
One word is regularly used to describe this hardy, tall Phlox: amazing! Phlox amplifolia 'Hercules' is unlike any other tall phlox; it produces huge pyramid-shaped clusters of bubblegum-pink flowers, each bloom accented with a delicate white eye. Each flower cluster can measure up to 38cm in length and 25cm in diameter at their widest point. The flowers are delightfully fragrant, too. However, the really amazing feature of this Phlox is that it can sometimes reach as much as 210cm in height!
Phlox 'Hercules' makes an amazing display at the back of a border, or in a large container, or even in a cutting garden: just one of these eye-popping flower clusters will create a full bouquet for indoor enjoyment, and will last a long time in water.
Grow Phlox amplifolia 'Hercules' in any moderately fertile soil, in full sun to part shade. It will be loved by bees, butterflies and other pollinating insects—while all human visitors will think it is simply ‘amazing’!

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.
