Our single white-flowered catclaw mimosa (M. aculeaticarpa var. biuncifera [earlier M. biuncifera]) is from a seed collected in Santa Elena Canyon in the Big Bend in the late 1970s. It is now some 9 feet tall, almost tree-like in form, with long lateral branches off its main trunk. It produces beautiful white flowers in mid-to-late summer. If better known, it might merit propagation as a native ornamental in Central Texas — but it is an invasive nuisance in the Trans-Pecos.
