Spiraea japonica is
a shrub of a height of around one meter, growing in sunny
gravel-rocky areas in hilly districts. Leaves are of alternate
phyllotaxis, 3-8cm in length, 2-4cm in width, ovate or oblong-ovate,
the bases circular to wedge-shaped, the tips pointed, and the
margins double-serrated unevenly. Leaf-bottom sides are light green
or glaucous, haired or non-haired - variable. Branch tops create
hemispherical compound umbels setting 3-6mm-in-diameter small
flowers in them. Petals are irregular in color, from light red to
deep red, rarely to white. Stamens, 25-30 in number, are longer than
petals, pistils are 3, and short curled pubescent hairs exist on the
inner surfaces of sepals. Bloom time: May-August. |
