Evergreen Ash

Fraxinus griffithii

Evergreen Ash is a small to medium tree used for screening and street planting in warm temperate areas; it tolerates a range of urban soils.

Key Facts

  • Evergreen or semi-evergreen small to medium tree.
  • Native to parts of Asia and used as an ornamental.
  • Has pinnate leaves that remain through much of the year.
  • Produces inconspicuous flowers followed by winged samaras.
  • Tolerates a range of urban soil conditions.
  • Commonly planted for screening and street tree use.
  • Moderate growth rate in suitable climates.

Evergreen Ash is a small to medium evergreen or semi-evergreen tree grown for dense foliage and screening in warm temperate landscapes. It tolerates a range of urban soils and fits street tree or privacy hedge uses where winter temperatures remain mild.

Identification

Fraxinus griffithii has pinnate compound leaves that remain through much of the year and produces inconspicuous flowers followed by winged samaras. The tree holds a compact to open crown on a single or multi-stem habit and is valued for year-round foliage rather than showy blooms.

Best uses and planting sites

Used commonly for screening, narrow hedges and as a street tree where space is limited. It tolerates urban soil conditions and performs best in full sun to part shade. Colder climates can reduce evergreen habit, so prefer warm temperate sites within the USDA zone range noted for the species.

Planting and spacing

Plan spacing according to the typical mature spread of about 12 to 30 feet. For a single specimen allow the wider end of that range; for a continuous screen space trees closer to the minimum spread. Planting season varies by region, so follow local timing to reduce transplant stress.

Soil and watering

Prefers well drained loam but tolerates heavier soils including clay, provided planting sites are not permanently waterlogged. Keep young trees watered regularly until established; poor drainage leads to root stress and decline, while tolerance of mixed urban soils makes it a practical option for many city sites.

Growth habit and size

Expect a mature height near 20 to 40 feet and a typical spread around 12 to 30 feet in favorable climates. Growth rate is moderate under suitable conditions, with fuller evergreen habit and quicker development where winters are mild and soil and light needs are met.

Propagation

Propagate by seed or by softwood and semi‑hardwood cuttings; grafting is used for named cultivars. Specific treatments such as stratification or cutting techniques vary by source and cultivar, so consult propagation references or local nurseries for method details.

Maintenance

Prune to maintain form, remove dead or crossing branches and control suckering or multiple stems as desired for screening. Monitor tree health and correct drainage or cultural stresses promptly; regular inspection helps prevent long term decline in urban planting sites.

Frequently asked questions

How fast does Evergreen Ash grow?
Growth is moderate in suitable climates, with faster development where winters are mild and cultural conditions are favorable.
Will Evergreen Ash keep its leaves year round?
It is described as evergreen or semi‑evergreen; leaf retention depends on local climate and winter severity so foliage may be reduced in colder areas.
How large does Evergreen Ash get?
Typical mature height ranges from about 20 to 40 feet with a spread of roughly 12 to 30 feet in favorable conditions.
What soil does it prefer?
It prefers well drained loam but tolerates clay and a variety of urban soils; avoid permanently waterlogged sites to prevent root stress.
How is it propagated?
Common methods are seed, softwood or semi‑hardwood cuttings and grafting for cultivars. Consult propagation guides for cultivar specific techniques.
