Cerasus incisa var. incisa f. yamadae ("Midorizakura")

Japanese name: ミドリザクラ （緑桜）
Scientific name: Cerasus incisa var. incisa f. yamadae

[Overview]
A deciduous shrub.
The trunk branches from the base, giving an umbrella-shaped crown.
The bark is purplish brown, irregularly and shallowly cracked, and dotted with lenticels arranged horizontally.
First-year branches are hairless, rarely hairy.
The leaves are obovate to ovate; the tip is long and tail-like, and the base is rounded to obtuse.
The leaf margin has doubly serrate, incised teeth that are somewhat sharp.
Both sides of the leaf have appressed hairs, which are somewhat denser on the underside.
The petiole has ascending or appressed hairs.
Two nectar glands are borne at the base of the leaf.
The flowers open at the same time as the leaves unfold, or slightly earlier.
The flowers are borne 1–2 per umbel in the leaf axils, hanging downward; they are white with 5 petals and do not open flat but are bell-shaped.
Both the calyx tube and the calyx lobes are green.

[Cultivation]
Propagate by cuttings or grafting.
It prefers a sunny, well-drained site.
If it grows into a large tree in a garden and becomes a problem, it is good to control the size of the tree by restricting the space for the roots to spread with a fabric pot.
While still a young tree, protect it from frost by, for example, laying straw around the base.
Also, it is better not to cut the branches needlessly if there is no need.
It suffers from many pests and diseases, so care is needed.
