I just put in 6 new vareigated pittosporums today, only somehow I ended up with at least one dwarf variety (I found one plant tag only and I have no idea which it came from). The buckets were unmarked and must have been mixed in with the regular sized ones. It appears that three of the plants have smaller leaves than the others, so I'm wondering if this is an accurate way to differentiate the dwarf from the regular variety?
