There is a Clematis Elsa, a pretty purple colour. Try googling it......

I typed "Elsa" into the RHS plant finder, Mavis, and got
1 Aubretia, 1 Clematis, 1 Fuchsia, 1 Iris, 1 Paeonia, 1 Tibouchina. So there is a choice, but not a huge one.
The Tibouchina was last listed in 2002 and the Fuchsia is the only "Elsa" without a surname. Good luck tracking one down - the RHS website links to growers so you can find out who's got what.
