Rather pleased with these, in the Alpine House. ( photo / image / picture from Palustris's Garden ) Dianthus erinaceus alpinus and ( photo / image / picture from Palustris's Garden ) Physoplexus comosus
The Physoplexus is one of those challenging plants which are supposed to be hard to get to flower. They are found in the European Alps. Don't ask me how to grow it, I just stuck a baby in the Crevice garden in the Alpine House and away it went.
