They're not too slow from seed and that's OK for the species. If you want one of the cultivars it will have to be buy and divide.
I don't like them much either. I had one called 'Shining Sceptre' but it only lived up to its name for a few days before looking nothing much.
I have one called 'Toffee Nose' which is as near to subtle as they get, I quite like it and haven't dumped it yet but probably wouldn't buy it again
