Carpinus laxiflora is a deciduous tree that can grow up to 15 metres tall
The plant is harvested from the wild for its wood and also for use as a cosmetic ingredient.
E. Asia - China, Japan.
Mixed deciduous forests all over Japan[
Carpinus species are generally tolerant of a wide range of soil types; they prefer a deep, open, moist but well-drained loam and can succeed in both clay and calcareous soils186, [
]. Plants, especially when young, do not demand much light[
An extract of the leaves is used as an ingredient in commercial cosmetic preparations as an antimicrobial, antioxidant, astringent, emollient and skin conditioner[
The wood is hard and close grained. It is used for turnery, carving, furniture etc[
Seed - best sown in an outdoors seedbed as soon as it is ripe[
]. Germination is usually good, though it may take 18 months[
]. If collected whilst still 'green' (after the seed is ripe but before it has dried fully on the plant) and sown immediately it should germinate in the following spring[
]. Grow the plants on for two years in the seedbed and then plant them out into their permanent positions in the winter. The average seed viability is around 65%[
Pre-treat stored seed with 4 weeks warm and 12 weeks cold stratification and sow in a cold frame[
]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in a cold frame until they are at least 15cm tall before planting them into their permanent positions.
