Lythrum
'Lady Sackville'
purple loosestrife
Reliable, upright, and richly coloured, Lythrum 'Lady Sackville' is a refined selection of the much-loved purple loosestrife, bringing vibrant structure to summer borders. Forming a neat clump of dark green, strap-like foliage, Lythrum 'Lady Sackville' produces sturdy vertical stems that rise confidently to around 80cm. From midsummer onwards these stems are crowned with slender flower spikes, each one studded with clusters of vivid purple-red blooms. The colour of Lythrum 'Lady Sackville' is particularly striking in warm sunlight, glowing against surrounding greenery and adding a lively vertical accent among softer perennials. Despite its bold presence, Lythrum 'Lady Sackville' carries an easy, natural elegance that suits both relaxed cottage-style planting and more considered border designs.
Thriving in moisture-retentive soil, Lythrum 'Lady Sackville' is especially at home beside ponds, streams or in damp borders where its upright habit provides welcome height and rhythm. Over time, Lythrum 'Lady Sackville' develops into a handsome, clump-forming perennial that returns each year with dependable vigour. The glowing flower spikes of Lythrum 'Lady Sackville' are also highly attractive to pollinating insects, bringing welcome movement and life to the garden through the warmest months. Combined with ornamental grasses, persicaria or late-flowering salvias, Lythrum 'Lady Sackville' delivers colour, structure and wildlife value in one graceful, easy-going plant.

Plant calendar
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.
