About This Plant
Sun or partial shade; (semi) evergreen, depending on conditions. Blooms appear in mid-summer and are sweetly fragrant. Gum bumelia’s descriptive names belie a rather humble appearance. “Bully” may be a bit of an overstatement, but the spiny branch tips definitely discourage close approach; “gum” refers to the chewy sap, and “woolly” to the fuzzy leaf surfaces. Gum bumelia is largely unavailable in the 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.) Make any cuts at a bud or branch, and trim no more than 25% of the total canopy during any five-year cycle. Leave the upper 2/3 of the tree’s height uncut — for example, on a 12-foot tree, stick to the lowest 4 feet.
15-40 H, 15-40 W
Terminal branch tips are spiny.
