Kerria japonica, a deciduous shrub, 1-2m in height,
growing in clumps, inhabits damp locations, for example, along
mountain rivers. New branches are green and ridged and turn brown in
due time, 3-4years in general. Leaves are alternate; blades measure
4-8cm long, 2-4cm wide, in the shape of an obovate or long-ovate,
with tips sharply pointed and bases round- or heart-shaped, and with
double serrations on margins. Cadmium yellow flowers set themselves
singly on the ends of new lateral branches. The flowers are 3-5cm
across; petals are obovate, tips round, and somewhat dented, with
many stamens and 5-8 females (styles). Bloom time: April-May. |
