It's all in the genes.

It’s about time I doused the fires of curiosity that are burning out there, fuelled by this photo.


When I asked ‘what is it?’ one or two of you were perfectly correct in saying ‘bindweed’. But, that’s not really what I meant. It’s what has happened to the bindweed that interested me. I hope it will you, too, and I’ll do my best not to send you to sleep while I explain something that no doubt every gardener will come across at some time or other.


It’s a phenomenon known as fasciation (fay-see-ay-shun), a condition that’s known to affect approximately 100 different vascular (having fluid-carrying vessels) plants. Stems that would normally be round, appear flattened, and look as though a number of stems have fused together. Any sideshoots usually fail to develop properly, but this bindweed obviously hasn’t read the manual!


It’s even developing flower-buds from the fasciated stem.
It can be caused by random genetic disruption, for example when the plant is stressed and cell production goes into overdrive. It can also be initiated by infection by the bacterium that causes leafy gall disease.
The condition is unpredictable and usually limited to a single stem. It seldom recurs the following year, although some plants appear to have a genetic tendency towards recurrence.
In some plants with ‘cristata’ in their nomenclature, fasciation is inbred and can be perpetuated by cuttings.
So next time you see a plant with a wide, flat stem instead of a round one, you’ll know it’s nothing to worry about. It’s just nature throwing a wobbly!


All eventually goes back to normal and carries on as if nothing had happened.

i have this on one of my shrubs. its odd but i like it.

Very odd, isn't it? Makes me inclined to think that we're descended from trees and that apes have nothing to do with it. If we're descended from apes, why are there still apes?

But then, why are there still trees?
