I don't think it is quite solved yet.
True Cardamom grows quite tall. Companies sell plants labelled as 'Dwarf Cardamom' when that may not be the correct name - there are no rules when it comes to common names. Unless companies label the plants with the botanical names many companies and individuals call a plant Cardamom when in fact it is a ginger and should be labelled False Cardamom?
I didn't explain that very well, but this link does a better job of it; see information regarding Elettaria Cardamom:
