About This Plant
Sun or partial shade; (semi) evergreen, depending on conditions. The spiny branch tips tend to discourage tree-climbing and other close contact, but blooms appear in mid-summer and are sweetly fragrant. Gum bumelia’s descriptive names belie a rather plain appearance. Although “bully” may be a bit of an overstatement, “buckthorn” references the spiny branch tips; “gum” the chewability of the sap; and “woolly” the fuzziness of the lower leaf surfaces. Gum bumelia is largely unavailable even in the native plant trade, so preserve it on-site if you can. It’s useful for wildlife in any native edge.
None required to achieve a shrublike shape, though it can also be trained up into a single-trunk tree (as pictured on recommended tree lists.) Pruning is always optional. Make any cuts at a bud or branch; focus on minimizing dead, damaged, or rubbing branches. As with any tree, remove no more than 25% of the total canopy during any five-year cycle. To maintain a healthy specimen leave the upper 2/3 of the tree’s height uncut (never removing more than the lowest third of the tree in a single pruning period) — for example, on a 12-foot tree, stick to the lowest 4 feet.
15-40 H, 15-40 W
Terminal branch tips are spiny.
