Fraxinus sieboldiana is a slender, deciduous tree usually growing 6 - 8 metres tall, occasionally reaching 15 metres in Japan[
The tree is probably harvested from the wild for use of its wood. It is often grown as an ornamental[
Fraxinus sieboldiana is a widespread and common species with no known specific threats. The plant is classified as 'Least Concern' in the IUCN Red List of Threatened Species(2018)[
E. Asia - southeast China, central and southern Japan, Korea.
Mountains and hills, C. and S. Japan[
]. Woods on slopes and by streams in ravines; at elevations from 500 - 1,200 metres[

Fraxinus sieboldiana is a moderately cold-hardy plant, able to tolerate temperatures down to around -20°c when fully dormant[
Prefers a deep loamy soil, even if it is on the heavy side[
]. Most members of this genus are gross feeders and require a rich soil[
]. Plants succeed when growing in exposed positions[
] and also in alkaline soils[
]. They tolerate atmospheric pollution[
A dioecious species - both male and female forms must be grown if fruit and seed are required.
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 soft, light and elastic. It is used for making furniture, utensils, baseball bats, tennis rackets etc[
]. Thin strips of the wood are used to give an ornately grained veneer[
The above report might refer to Fraxinus longicuspis, a distinct species that has in the past been confused with Fraxinus sieboldiana[
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.
