Lynn if you have frost then maybe at most nine feet. Frost kills it back by two thirds every year so its slow. First year you will have to put a thatch wigwam around it in winter then its ok. In its natural habitat its huge. Argentina is on/near Equator.

Sorry, that statement is wrong about Argentina. It grows towards the equatorial end but is there a frost free zone 8 or 9 there? Funny the way frost sets it back but in a way its good, keeps it under control.

Yes, it gets hit by frost every winter. Lowest winter temperature is minus five Celsius. Heavy frost can also fall if it rains in the daytime and a clear sky at night. Then minimum goes down to dew point. This plant is four years old and has been hit by three winters and this will be the fourth.
