Spiraea Trilobata

 

Threelobe Spiraea

Medium size flowering shrub with dark green oval shaped leaves. Forms clusters of white flowers in late spring. Needs to be hard pruned every 3 years. New: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. Profuse, white florets in clusters on the ends of the branches. 'Threelobe Spirea' is a small, rounded shrub that bears terminal clusters of white florets in Spring, flowering well even in shade. The foliage is blueish green, turning yellow in Autumn

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.
