Coleus.Won't survive our winters outside. You can overwinter cuttings if you have anywhere to keep them.

I take cuttings about now and keep them frost free in the conservatory.

Many thanks to you both. I saw them in a public garden in Kent today and just wondered what they were.

In a public garden they are treated as an annual and ripped out fairly soon.

dead easy to grow from seed in spring (cold frame or indoors) though, and that way, you get to choose the best colour combinations that you like

Changed their name to Solenostemon so if you go looking for seeds they may be sold under the new name.
