I have a hoya carnosa and it has been in the same terracotta pot for 20 years in the same north window(zone 5 Indiana ) and blooms freely several times a year .
before that it spent 12 years just rooted in water , less blooms but grew like crazy in a west window. (zone 4 Michigan )
The plant was a two leaf cutting given to me by a family friend in 1972
I think they are friendly easy plants
