I took this pic when I was in Chicago last week. It's really tall but it's possible it maybe sitting on a platform. It's still tall though. I am not sure if it's a grass or a plant. When I first saw it, it looked similar to my annual purple fountain grass. Can someone please id it?
Here's a cluster of 3 'Princess' which came to me as 3" pots in early July:
They're just under 3' tall now. They and 3 copies of 'Prince' are an experiment in hardiness for me. They're rated for 7b, and I put them in the warmest bed in my garden, right next to a large blacktop driveway.
