Fraxinus griffithii
Evergreen tropical ash
Fraxinus griffithii
Fraxinus griffithii, the Himalayan Ash, is a fast-growing deciduous tree native to the Himalayas and parts of Southeast Asia. It's known for its attractive compound leaves, which provide light shade, and its relatively small size compared to other ash species, making it suitable for smaller gardens. It is adaptable to various soil types but prefers well-drained soil and full sun exposure. It can be susceptible to pests and diseases common to ash trees.

Cultivars

Hydrangea macrophylla
mophead hydrangea
Hydrangea macrophylla
Hydrangeas thrive in similar light and soil conditions as Fraxinus griffithii, creating a visually appealing combination of textures and colors. The ash tree's light shade can protect the hydrangeas from harsh afternoon sun.
Asarum canadense
Canadian wild ginger
Asarum canadense
Wild Ginger is a shade-tolerant groundcover that can help suppress weeds and retain moisture around the base of the Fraxinus griffithii while benefiting from the dappled shade it provides.
Acer platanoides
Norway maple
Acer platanoides

Norway Maples are known for their aggressive root systems which can outcompete Fraxinus griffithii for water and nutrients, especially in close proximity.

Emerald Ash Borer

This invasive beetle is a serious threat to ash trees, including Fraxinus griffithii. Larvae tunnel under the bark, disrupting nutrient and water flow, ultimately leading to the tree's death. Signs of infestation include D-shaped exit holes in the bark, thinning canopy, and epicormic branching (sprouting from the trunk).

Ash Flower Gall Mite

These mites cause abnormal growths or galls on the flowers, which can be unsightly but generally don't cause serious harm to the tree's health.

Steps:

    • Collect fresh seeds in the fall.
    • Stratify seeds in moist sand or peat moss for several months.
    • Sow seeds in a well-draining potting mix in spring.
    • Take semi-hardwood cuttings in summer.
    • Dip cuttings in rooting hormone.
    • Plant cuttings in a moist, well-draining potting mix.
    • Keep cuttings in a warm, humid environment until rooted.
