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 of a kind, Geranium 'Joseph Green' is particularly notable for its unusual double blooms—as far as we're aware it's the only Geranium phaeum which flaunts such petal-packed flowers. It maintains the dusky cranesbill colour—a luxurious deep purple—but throws in a zest of zingy lime among its tuft of small inner petals. You can enjoy these geraniums in the shadier, damper areas of the garden because this variety thrives in such conditions, flowering on tall stems which adds interest at a height along with a floaty, swaying motion.
Flowering from early to mid summer, Geranium phaeum 'Joseph Green' will burst into bloom with excellent timing to take over from fading spring tulips. Other plants which flower at around the same time include Allium, Geum and Dicentra, all of which make excellent planting partners in a partially shaded spot. This double cranesbill is a hardy and highly resilient perennial which copes with freezing temperatures in winter as well as summer heat. Plant it in dappled shade for best results, because it prefers to sink its roots into a damp soil.

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.
