Salix Irrorata Blue Stem Willow
If you want a low-maintenance deciduous shrub with winter interest, you cannot go wrong with Salix Irrorata or Blue Stem Willow, as it is more commonly known. As its name suggests, this willow variety sports striking young stems that vary from blue to lavender. The bare branches with vibrant colouring are particularly striking when bare, during autumn and winter but this willow variety offers year-round interest. In addition to being highly decorative, Blue Stem Willow is easy to care for and quite resilient. All of these impressive traits earned it the coveted Award of Garden Merit by Royal Horticultural Society.
Salix Irrorata is a bushy upright deciduous shrub that has showy young purplish stems that bear narrow, oblong leaves. In the winter, this shrub also produces white blossoms, followed by grey catkins with red anthers in the spring.
Height and Spread of Salix Irrorata
Blue Stem Willow is a compact shrub, ideally suited for small gardens. Its expected maximum height is 1.5 to 2.5 metres, with a spread of 2.5 to 4.0 metres. This is a vigorous, fast-growing willow variety - it will not take long for it to achieve its full size.
How Hardy is Salix Irrorata
Robust and tough, this US native fares well in the British Isles. Blue Stem Willow is fully hardy and will thrive in most areas of the United Kingdom, even if the winters get severe.
How To Use Salix Irrorata
Winter is the time when Blue Stem Willow is at its most striking, but it is undeniable that this showy plant offers multiple seasons of interest. Grow it on its own on a lawn or near a patio for an eye-catching display of lavender-bluish branches, or plant in a mixed shrub border, where its unusual hues will beautifully contrast the usual shades of green.
How To Care for Salix Irrorata
Easy to grow and to care for, Blue Stem Willow is really an undemanding variety, right from the very start. Plant it in full sun to partial shade, and in any moist but well-drained soil. If needed, cut back any dead growth or congested shoots.
