Gardeners' Notes:

Sure about the hardiness information? All other sources give Euonymus japonicus zone 6 at best, with concensus settling around zone 7.

Traditional wisdom says it will tolerate -10C at most.

These are very susceptible to euonymus scale. Once you have an infestation, it is very hard to get back in control. Luckily, euonymus scale does not spread to anything other than euonymus. Neem oil works better than any chemical insecticide I've used on my euonymus. Also, these shrubs do best with a fair amount of sun. I have one in near total shade and it is pretty scraggly compared the two I have in part sun.
