Sempervivum 'Exorna'



A plant that came to me as part of a trade with a grower in the Czech Republic. I was very grateful, I got some lovely things. 'Exorna' was raised by Len Earl in the UK and introduced in 1970. It was given an Award of Merit in 1980.
Horst Diehm sid:

"beautiful velvety leaves, mixture of pink, green and red, takes on a bronze color in summer"

Erwin Geiger is quoted on Sempervivum List:

"A hybrid with rosettes up to 10 cm in size, which stands out at any time of the year. Plays with olive green to reddish brown tones throughout the year. The leaves are very hairy, which gives the plant a velvety sheen. The salmon-colored speckled large flowers are also striking. Identical to the Belgian S. 'Charline'."

Craigiehall Nursery say:

"From dusky pink/grey in spring, 'Exorna' changes to an entrancing bronze colour in summer. It's so different it stands out in any collection. Large rosettes, broad leaves which have a velvety sheen. Outstanding!"

Sempervivums by Post say:

"'Exorna' won a prestigious Award of Merit in 1980 from the now-defunct Sempervivum Society. This award-winning houseleek is a velvet beauty with colours ranging from olive green to deep red. Different. A British introduction from 1970 by Len A. Earl."
