banker07 said:sometimes there are crested offsets on a named cultivar;

but often this crested offsets are not stable; they come back to the normal form or produce only normal offsets themselves;

this crested offsets should not get an own entry to the database or an own name because you can't increase;

when crested offsets were seperated and selected there might be some few stable which produce crested offsets themselves; then it is a good idea to add an entry to the database with the name S. 'name crested' - it should take the breeder-informations of the normal form;

it is no good idea to give them an own name because it may turn back to normal even after years;

f.e. S. 'Bedivere' often produce crested offsets; I've seperated a lot of them and only a few increases crested; after 4 years of screening now there are some stable ones:

• Hen and Chicks (Sempervivum tectorum 'Bedivere')

I think for S. 'Bedivere crested' it is reasonable to create a database-entry !?

about the requirements for a crested plant given it's own entry if it is reproducing crested offsets. Do you have a photo of your Bedivere crested with crested offsets? I would love to see that.


This one appeared this year. Keeping an eye on it to see what happens. But I think it is probably crested because of trauma. I moved this colony late this spring.


Sandi can you show us a photo of your crested Dream Catcher?

Nice crested Cebenense Janice.

twitcher said:Peter, I decided a while back to spend more time working with the unusual forms in the semp world. I set out to acquire as many of the unusual forms as I could, including those that have a reputation for throwing crests. So I have a few in my collection to track. I agree with your nomenclature regarding S. 'Bedivere Crested'. I follow the same convention with regard to the crests I have.

So far, the following have crested for me and I have viable, but not yet stable, crested plants growing. Sopa and Deep Fire have produced offsets this year. Deep Fire's offsets appear normal, but the Sopa offset is itself crested.

S. Sopa
S. Borimere
S. Deep Fire
S. Mauna Kea

I also have Fuzzy Wuzzy, known to crest, in my collection but so far is has remained normal. My Mauna Kea normal produces a couple of crested plants each year so far. Most of them do not survive long, so last year I started transplanting them so that I could provide more attention.

Do you have/know of a list of the varieties known to produce crests? I'm trying to get Weirdo and Whirl-i-gig added to the my unusual forms collection but they are hard to come by here.

Fascinating topic and thanks for starting the thread.

Sempervivum Sopa Crested w crested offset

Wow twit, now if that little offset will produce crested offsets.
