It is also a valuable wildlife tree, hosting several butterfly species and feeding birds with its fruit.

Planting
How to Grow
- Plant in almost any soil type, from wet clay to dry sand.
- Select a location in full sun for best growth and form.
- Dig a hole twice the width of the root ball and just as deep.
- Set the tree in the hole with the root flare at or just above soil level.
- Backfill with existing soil and water deeply to settle.
- Mulch around the base to conserve water, but avoid contact with the trunk.
Pro Tip
Embrace its 'flaws' like nipple galls and witches' broom; they are characteristic and rarely harm this incredibly tough tree.

Don't
- Do not be concerned by cosmetic issues like leaf galls.
