It looks like an inchworm (geometer moth caterpillar). Can't really narrow it more than that.

The plant is a Cape Primrose - Streptocarpus. You can propagate them from leaves if any visitor wants a cutting.

Streptocarpus, yes, and a beautifully grown one.

Thank you for that. I must have known at one time. The name is familiar. It's in east facing picture window and seems to get just the right indirect sunlight.

A couple of cuttings in a small vase on the kitchen sink lasts an amazingly long four weeks or so.

The biggest Streptocarpus grower in the UK is Dibley's Nursery. Here are their instructions for taking cuttings. Not as cut flowers but to make new plants for your friends. It really is very straight forward.

Here is a link that might be useful: Leaf cuttings

Thank you for that tip and the link. I've had a few pleas for something to bring home and each time I've unearthed a rooted section. I don't know if it is typical of this species, but rather than one large rooted growth there are many scattered in the soil beneath the leaves. Very easy to nab a small one. But from now on I can send folks off with a leaf and instructions from that link.

Like I mentioned, there is something particularly attractive about this flower. I've got some exceptionally beautiful orchids in my office space and a couple of flowering Maple and Bougainvillea in other parts of the house (i'm most fond of papery colorful delicate blooms). Last year I had a large old Hibiscus with a solid one inch trunk that just would not stop producing mind-blowing six inch diameter blooms all over like fireworks for months straight. Sadly, I left it on the deck through a couple of early frosts and lost it.

Still, everyone seems to swoon over the Cape Primrose.

Thanks for the info guys.
