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
Aster 'Jenny' is a delightful, compact perennial that brings a burst of vibrant colour to the garden in late summer and early autumn. Its charming, daisy-like flowers, in a striking shade of deep magenta-pink, are set against a backdrop of fresh green foliage. Aster 'Jenny' is known for its abundance of blooms, which create a lively and cheerful display, brightening up borders just when other summer flowers are beginning to fade.
Aster 'Jenny' thrives in full sun to partial shade and prefers well-drained, moderately fertile soil. It’s perfect for the front of borders, cottage gardens, or wildlife-friendly planting schemes, where its compact size makes it easy to integrate into mixed plantings. Aster 'Jenny' is also an excellent choice for filling gaps in late-season borders, bringing vibrant colour when many other plants have finished flowering.
Aster 'Jenny' or Symphyotrichum 'Jenny' is a fantastic plant for attracting pollinators, especially bees and butterflies, which flock to its nectar-rich blooms late in the season. This variety is hardy and easy to grow, providing reliable late-season colour year after year. Its compact, bushy habit makes it an excellent choice for smaller gardens or for edging larger borders, and it can also help to extend the flowering season well into autumn.

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.
