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.

Sesleria heufleriana
Balkan blue grass
Compact, graceful and quietly distinctive, Sesleria heufleriana—commonly called Balkan blue grass—is a delightful ornamental that brings texture and movement to the garden year-round. This densely tufted, evergreen grass forms neat clumps to around 70cm high, with slender leaves that emerge bright green in spring before maturing to a cool blue-green with silvery undersides as the season unfolds. Early in spring, fine upright stems rise above the foliage, topped with dark purple spikelets that fade to soft white as they open, creating a subtle yet elegant contrast against the shifting tones of the leaves.
Wonderfully easy to grow, Sesleria heufleriana thrives in full sun and well-drained soil, where its colour and form can truly shine. Its tidy habit makes it ideal for edging borders, softening pathways, or adding structure to gravel gardens and containers. Hardy and drought-tolerant once established, it keeps its poise throughout the year, even in exposed sites. Whether used en masse for a serene, naturalistic effect or as a delicate accent among perennials, Sesleria heufleriana lends lasting texture and a whisper of the wild Balkan hills to any planting scheme.

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.
