Hydrangea hirta is a deciduous shrub that can grow up to 1.00 metres tall.
It is harvested from the wild for local use as a food.
E. Asia - C. Japan.
Tolerates most soils[
], thriving in a well-drained loamy soil[
], but resenting dryness at the roots[
]. Succeeds in full sun or semi-shade[
], but if it is grown in a low rainfall area then it requires shade at the hottest part of the day[
]. It grows well on very acid soils with a pH around 4.5[
Although the dormant plant is quite hardy in Britain, the young growth in spring can be damaged by late frosts.

Leaves - cooked[
]. Eaten with rice[
Seed - surface sow in a greenhouse in spring[
]. Cover the pot with paper until the seed germinates[
]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts.
