What is Griffith's Ash
Griffith's Ash (Fraxinus griffithii) is a (semi-)evergreen tree of the genus Fraxinus griffithii in the family Oleaceae, native to Southeast Asia. It is from warm regions, so although it is evergreen, its leaves sometimes turn brown in winter. It is also called Formosan ash, Fraxinus, or Griffith's ash, from the species name and the color of the bark.
The tree is 15-18 m tall and has grayish-white bark. The leaves are green, glossy, and oddly pinnate. The lobes are 3-10 cm long and 2-4 cm wide, oblong-ovate, in 7-13 pairs, with wavy margins, and are attached to the branches in opposite pairs. It is dioecious, cool-weathering, and has a fragrance characteristic of the Moraceae family.
In early summer, a 10-25 cm long conical inflorescence grows from the tip of the flower stalk and produces white flowers similar to those of the Chinese privet, scientific name: Ligustrum lucidum. The flowers are bell-shaped, about 0.5 cm in diameter, with 3 or 4 lobes and recurved lobes at the tip. Two stamens with orange anthers open from the petals, and a spatulate white winged fruit is produced from August to September.
The tree is used as a roadside tree, garden tree, potted plant, houseplant, and, in rare cases, as a beetle collector.
