Cosmic Traveler grows OK here, but does not like our drastic High/Low Spring temps. I nearly lost it the first year here, but since then it has done well. It makes seed, both ways, and I can not wait to see the results. It has yet to hit it's registered 25" scape height. The best it has done is 16". TET Connie Burton does that to crosses, so best to cross it with flowers that have good, reliable scape height of 28" or better. One can not ask for much better in flower fullness, color saturation, and ruffling. It has smooth texture with diamond dusting in sunlight. It is one of my friend Dan Trimmer's best achievements.
