I would guess the roman numerals refer to the 4th and 5th month.

Hi;
My wife has bought the above plant. There are a number of "Friendly"
icons,
including one which says it will grow to 80-100cm, though the internet
would
claim more like 10ft?
Also, the label has an icon which shows a flower - fully open, with 'IV-V'
against it ??
Lastly - will it be happy in a pot, please?
Many Thanks for any help
