i found that it is also referred to as croton johannis. i would like to add this info to the entry, but i can't figure out if this is an 'outdated' name or common name or what.
sev places that sell it refer to it as croton Johannis type, but in actuality there are sev johannis types and this particular spotted one is also labelled 'johannis type 3'.
but often sellers just say 'johannis' or 'johannis type'.
this is what i found
