multi-hybrids

Is this just a 'catch-all' word used to describe plants that have been crossed with so many plants that no one knows what they are? Or is there a more technical explanation?

I was wondering that my self and was wondering what the guildlines for crossing as in what can you get from such a cross?????????

Liz, we have to wait for Monikas explanation. However I can entertain a bit while we wait, with mine lol

A multi-hybrid is a cross involving more, than two species lol versicolor x suaveolens x aurea or x insignis ( (suaveolens x versicolor) x suaveolens) x aurea or x flava (sanguinea x arborea) x vulcanicola ...

Monika, Brugs are too new to me. Do you have the real explanation lol ?

Liz explained it already exactly. These Multihybrids often named only Brugmansia - hybrids, even when they look like a pure species. But when used for crosses, the gene mix shows in the offspring. They cannot be placed into the B. suaveolens-, aurea, versicolor, x candida or x insignis group. The parents of a B. versicolor - hybrid must be pure B. versis, the same fits to aurea or suaveolens. B. x insignis is a natural hybrid from, so is B. x candida.
How confusing this can be, Tiara is placed by Dr. Preissel as a B. versicolor flore plena hybrid, buts its sister Charleston, raised out of the same seed pod, as a B. x candida flore plena. From the botanical view, this is not correct. I placed Tiara in x candida flore plena, because: the parents were B. x candida flore plena x B. versicolor Kaskade. Tiaras shape of the buds looks more like that of versicolor but the flower resembles more a x candida.
Fandango resembles in shape of flower a x candida, in flowering habit a versicolor but is a Multihybrid, because the genes of all three species are united in this hybrid.
The same fits to Anouschka. The two are Brugmansia flore plena hybrids.

Thanks Monika - I've re-read your reply about three times - maybe I need more coffee.
So any hybrid crosses with more than two different hybrid group parents become a multihybrid?

Liz, is my explanation confusing?

The x between two names means always a cross: versicolor x versicolor = versicolor hybrid. The x after the species name means, that this is a hybrid, B. x candida or B. x insignis.

No Monika - your explanation was perfectly clear - I read it early this morning and my brain was still asleep.

LOL are you here first time in the morning too, Liz. I too lol When I am real busy I turn on the computer and put over water for coffea and spend the time to the water is boiling watching all the new posts lol we must be real brugbrains lol

I'm with you Tonny - I can't pass the computer without checking daves to see what's new.
I read Monika's posts at 3am PST.
