Spiraea x cinerea 'Grefsheim'
Spiraea 'Grefsheim'
Spiraea plants are hardy, deciduous shrubs. They may be grown as specimen shrubs and also make attractive hedging plants. Varieties are either early flowering, producing the blooms on previous season's growth, or late flowering, blooming on the current season's growth. All spiraeas thrive in full sun but can tolerate light shade. 'Grefsheim' is an early flowering spiraea which bears small white flowers against a mass of grey-green leaves on arching branches.

Planting young plants
From Late Autumn TO Early Spring
Plant young plants in any fertile, moist but well-drained soil in full sun or light, partial shade, between late autumn and early spring. The new plants should be kept moist while they are getting established. A shovel full of well rotted compost in the planting hole will help the shrub establish and aid water retention.
Propagation by cuttings
From Late Autumn TO Early Winter
Spiraea is best propagated by hardwood cuttings taken when the shrub is in the dormant period - late autumn after the first hard frost or early winter, or in early spring. Take 10 - 20cm cuttings from the upper area of the shrubs. Slant the cut below a node with a clean, sharp knife, wrap in plastic or heavy paper with lightly moistened peat moss and store in a cool place until spring when they can be set in the soil with the top up and at an angle of 45 to 60 degrees. They should be buried to within 1 inch of the tip.
