I don't have either one, but just going by the photos it doesn't look the same to me, kew tip. A lot of fasciata hybrids have kind of a similar look, though, and this is definitely a fasciata hybrid. Check FCBS and you can find a bunch more, but none of them look like a perfect match. I'd assume it is what it says it is.

Here's another picture of it:

Here is a link that might be useful: Ae. Twin Creeks

Thanks for the reply Lisa. I seem to have come full circle now. The link is for the nursery where I originally bought the plant and they gave it that name because they heard it had come from Twin Creeks Nursery! This nursery is long out of business. I have visited them but the gates are barred and there are warnings of fierce dogs! Your comment that none of the fasciata hybrids on FCBS look like a match confirms my own findings. I'll keep trying the local sources.

Just to add to the confusion ;-) I took the photo of A. 'Pink Rocket' on the Exotica site. The flower initially looked like the image above. It took a couple of months to open fully. (It's still in flower at the moment) The A. 'Twin Peaks' photo looks as though it has a much shorter stem and heavier leaf serrations. All 3 could be different though - need someone to start measuring petals, anthers etc (bags not)

Just run between the rain to grab ours from the garden. Lives hidden in the background so not had too much care, Surprised to find it in flower. This is quite a hardy plant. The plant gets baked in the full summer sun and the leaves turn bright red, sorry no pic of it at that stage. The leaves become quite green in low light as our conditions are now.
