I would say having them here there is defiantly a big difference they are both hespires but softer velvet narrow itleaves better flowers softer stem not prickly. I will put up some close photos. I did come across a new hespires last year at wisley plant center it was very expensive and they couldn't tell me with confidence of how it was propergated it had more stunning flowers but alas no info on it.

the slim hairy-ish is closer to the wild form. but when a variant comes along they are often kept and bred from or given a cultivar name. I have the slim hairy form and most of their offspring are more like it but they do bush out as they get older.

there can be quite a lot of variation in the leaf so I'd say they both are. Though the forms I have are more like the first photo.
