Sedum telephium Yellow Matrona = ‘Eline’ (PBR) (stonecrop) £6.99
Position: full sun Soil: moderately fertile, well-drained, neutral to slightly alkaline soil Rate of growth: average to fast-growing Flowering period: August to October the dried flower-heads provide colour and structure in the winter garden Hardiness: fully hardy Dramatic, deep bronze-purple succulent leaves topped with yellow flower-heads from August to October. Ideal for a sunny, well-drained border or in a large patio pot, the flower-heads are a valuable source of nectar for butterflies and bees. Garden care: The flowerheads look great left during the winter to add shape and texture to your border. In February and March cut back the old flowerheads and apply a generous 5-7cm (2-3in) mulch of well-rotted garden compost or manure around the base of the plant. Once established, sedums can have a tendency to flop leaving an open and unsightly centre, especially in fertile soil. One technique to help prevent this is the ‘Chelsea chop’. During the last week of May (Chelsea Flower Show week), cut one in every three stems back to the ground. This will produce plants that are less lush and flower slightly later.
