I have two different Phygelius species in hanging baskets. They are magnets for the hummers, and should be perennials here, but they don't make a pretty plant in pots. ...at least here. They are not self cleaning. The seed pods hang on forever, and if you deadhead, you don't get new flowers, as they just keep growing from the same spike, and much like the Pelargoniums, the dead leaves hang on too.
The Epilobium is pretty!
