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
Enjoy speedier results with Agapanthus umbellatus XXL! These African lilies are supplied as well-established clumps which are ready and raring to grow—plant one of these satisfyingly chunky clumps straight out into pots or sunny borders and you’ll be soaking up a wash of blue each summer when they burst into bloom. Agapanthus can take time to settle in but clumps like these are quicker to establish and will soon look like they've been growing in the garden for years. Depending on planting location, conditions and how early in the season you plant them, you may even enjoy some blooms in the first year!
This classic variety is loved for its long-lasting umbels of cool blue flowers on strong, upright stems in the height of summer. They’re reliable and easy to grow in any sun-trap location and quite like having their roots restricted too, which makes that a great choice not only for borders but also for a narrow spot along a south-facing wall and patio containers. If you like picking fresh flowers from the garden to make bouquets, Agapanthus umbellatus XXL produce some fantastic stems for a tall vase!

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.
