Spacing 'Lady in red'
Can anyone recommend how far apart these should be spaced? I'm in Louisiana and everything seems to get big thru the long summmer. I don't want them to grow into a big tangled mess by midsummer. The tag says 12in but I know that's far too close because I grew them many years ago and they seemed to take over and grow thru everything. I just can't remember how I planted them. I don't mind triming now and then- just don't want to have to hack them back all the time. Thanks
