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
If you're looking for an easy-to-grow, low-maintenance, attractive, fragrant and long-lasting plant which is a magnet for pollinators, Agastache 'Alabaster' will tick all those boxes! Commonly known as white-flowered Korean mint, this perennial grows into a bushy plant with aromatic leaves—you can catch the fresh, minty fragrance on a warm day or when the leaves are crushed. Each stem of Agastache 'Alabaster' is topped with a cluster of nectar-rich flowers which will bring in the bees and butterflies from midsummer to early autumn.
This Korean mint is a fully hardy, clump forming perennial which grows back every year, bushier and more prolific each time. Growing to around 90cm tall when established, it's perfect for filling out a space in the middle of a sunny border. Agastache rugosa 'Alabaster' is not fussy about conditions and will grow in most soil types as long as it's positioned in full sun. It'll cope well with summer heat and drought as well as winter cold.

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.
