During what is winter in North America, spider aloe (Aloe × spinosissima) produces a profusion of unbranched spikes of brilliant orange-red flowers—a favorite of hummingbirds in its native growing region of South Africa. This hybrid will tolerate temperatures down to 25 degrees Fahrenheit for short periods of time, but it grows best in full sun, in frost-free environments with well-drained soils.

The specific epithet of this cultivar refers to the abundance of blunt-tipped spines along the leaf edge.
