Camellia japonica is an evergreen tree growing up to 5 to 6m
from the ground, growing wild in forests, especially not far from
the seacoast, bearing 5-to-7cm-across single-petalled, dark red flowers on
it in wintertime. Parted petals connect themselves at the base with
the base of stamens. So, C. japonica let its petals drop
together with the stamens, leaving the sepals and the pistil on it.
The fallen flowers on the ground can look as shapely as the other ones
still on the branches.
