Salix integra is a small deciduous willow shrub from East Asia, grown mainly for its variegated 'Hakuro Nishiki' cultivar, usually sold grafted onto a straight stem of another willow. Remove any shoots that sprout from the rootstock below the graft, since they are unwanted growth.

About
Salix integra is a species of willow native to northeastern China, Japan, Korea and the far southeastern Russia (Primorsky Krai).
It is a deciduous shrub growing to 2–6 m tall with greyish-green bark and reddish to yellowish shoots. The leaves are 2–10 cm long and 1–2 cm wide; they are pale green both above and below, and unusually for a willow, are often arranged in opposite pairs or whorls of three, rather than alternate. The flowers are produced in small catkins 1–2.5 cm long in early spring; they are brownish to reddish in colour. It is dioecious, with male and female catkins on separate plants.
How to grow it
The cultivar 'Hakuro Nishiki' (dappled willow) is widely grown as an ornamental plant for its variegated foliage, the leaves strongly mottled with patches and blotches of white and pale pink. As its growth is fairly weak and shrubby, it is commonly sold grafted on the top of a straight stem of another willow. It has gained the Royal Horticultural Society's Award of Garden Merit.
Ultimately, you would like to prune the Salix integra in the shape of a globe for the first 3 years, then, check the main stem below the head and prune away completely any growth from it. Salix Integra generally are grafted onto a quick growing willow variety and any growth from the main stem is unwanted.
