    Nursery contributed plant descriptions

    A very prickly shrub, as one of its common names, crucifixion thorn suggests, but also striking with its tiny, inconspicuous, deciduous leaves on gray-green, rounded spine-tipped stems that do most of photosynthesis. Produces abundant, tiny, scented, tubular, white flowers in late summer-autumn. Slowly to 4-6 ft tall and wide, (larger over a long time but clippers can be used) in full sun and well-drained soil. Drought tolerant but accepting of summer water. Frost hardy to 10° F, USDA zones 8.
