Practical Plants is currently lacking information on propagation instructions of Oplopanax horridus. Help us fill in the blanks! Edit this page to add your knowledge.
A very hardy plant, tolerating temperatures down to at least -15°c, but the young shoots in spring can be damaged by late frosts. It is therefore best not grown in a frost pocket. This species was until recently considered to have its range in N. America and Japan, but the Japanese form has now been separated off into its own species as O. japonicus. A very ornamental plant, but it is densely armed with spikes. It transplants easily and also tolerates pruning.The leaves and stems are excessively spiny.
