Gazania linearis Colorado Gold question

Submitted by externmed on

Gazania linearis Colorado Gold.
Anyone growing this in zone 5 or 6 east of the Mississippi?  Of two nurseries I found listing it, one said Z5 and the other Z7.  Guessing that Z5 is in Colorado and Z7 is in North Carolina -- like so many others.  I did buy one locally because it has small red markings, rather than the usual all yellow or brown markings.
Will keep it indoors the first winter, then maybe will have some to try outside in a dry sheltered location.
