I just got Sheila's Perfume too! I had Cupcake some years back.. Not sure what happened to it, but I remember it was awfully sweet.
I planted one called Pax today. I don't know anything about it, and all the nursery could tell me was that it was a local hybridizer... so we'll see what happens there.. This is a very sandy bed, so digging was fairly easy. Everywhere else is pretty squishy.
