Fraxinus chiisanensis is a deciduous tree
The tree is harvested from the wild for local use as a food and source of wood.
Fraxinus chiisanensis is endemic to the south of Korea, where it is severely fragmented and found in only nine locations. There is clear and documented evidence of a continuing decline in quality and quantity of habitat due to a number of factors which include the effects of deforestation. The plant is classified as 'Endangered' in the IUCN Red List of Threatened Species(2016)[
E. Asia - South Korea
Forests, especially along mountain streamsides; at elevations from 600 - 1,400 metres[
]. Eaten occasionally[
]. The young leaves are softer and less bitter than older leaves[
Fraxinus species in general are gross feeders with an extensive, fibrous root system, which makes transplanting easy, but means that other species will often not grow well if planted nearby, especially if they are shallow rooted[
The wood is used for construction materials, craft materials[
The seed is best harvested green - as soon as it is fully developed but before it has fully dried on the tree - and can then be sown immediately in a cold frame[
]. It usually germinates in the spring[
]. Stored seed requires a period of cold stratification and is best sown as soon as possible in a cold frame[
]. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in a cold frame for their first winter. Plant them out into their permanent positions or a nursery bed in late spring or early summer of the following year.
If you have sufficient seed then it is possible to sow it directly into an outdoor seedbed, preferably in the autumn. Grow the seedlings on in the seedbed for 2 years before transplanting either to their permanent positions or to nursery beds.
