Yellow phygelius

This is one of the plants we found in the garden when we moved in. We were not sure what it was and were tempted to just pull it out, but we are glad we left it now. Having identified it online, we believe it is sometimes called the Cape Fuschia, and flowers all summer. The yellow varieties are called Yellow Trumpet, Colourburst and my personal favourite Moonraker, but we don't know which it is.
