Drought tolerant once established. Often used to form a "living barbed-wire fence." Good choice for livestock containment, privacy boundary due to the wicked thorns.

MrsBinWY On December 15, 2017 Seeds sown
From janinilulu. Seeds had been refrigerated 30+ days. 4 out of 5 seeds rotted in shipping. Disinfected remaining seed w/H2O2 half an hour or so & sowed at warm room temp. Checked ~10 days later and found this seed had rotted, too.
