Betula Pendula
Does anyone know whether the weeping birch, Betula pendula "Youngii" comes
true from seed? I have also seen some weeping Ash trees (Fraxinus exelsior "pendula" ?) growing locally and wonder whether the same applies, or whether it's cuttings/grafting only. Christina |

I have also seen some weeping Ash trees (Fraxinus exelsior "pendula" ?) growing locally and wonder whether the same applies, or whether it's cuttings/grafting only. Christina Young's birch is an exceptional form of B. pendula and afik is a named clone. Occasional exceptionally weeping forms of B. pendula will occur in any large (no idea how large) batch of seedlings, this is typical of the normal variation found in most species. None of those seedlings will be Young's birch - all Young's birch are vegetative clones of the original seedling. I don't know of any named clone of weeping Ash. We have a large specimen here which sheds huge numbers of seeds and we have them coming up all over the place. Seedlings with the weeping habit are not uncommon but are again only a small (no idea how small) proportion of the total. I would guess that the proportion of weeping seedlings from a batch of seeds taken from non-weeping trees would be significantly lower. That's the best this gardener can do, you need some geneticists and statisticians to get a clearer explanation. BTW grafting scions of a weeping ash onto non-weeping seedlings is quite easy.

Many thanks for your authoritative reply Rod. My skills at grafting are as
yet untried, although I have rooted lots of cuttings of various trees and shrubs (my home-made mist propagation is a godsend). I shall keep a keen eye on my seedlings to watch for "weepers". Many thanks, Christina |
