Cape Fuchsia

Otherwise known as  Phygelius, the trumpets are yellow inside. Also available in yellow and a range of in between shades of pink-yellow. This one is the Funfair series. Funfair Pink.

 They can creep quite a lot, and if you want to restrain their roots, I plant them in their plantpot, though with the bottom removed. Roots then will go down and not sideways.
