Spiraea japonica is
a shrub of around one meter in height, 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. |
