I think that's probably fasciation, don't you - so you could leave it and chop it off later, I'd say. I've never seen it on a Daphne before, though! Weird!

First time that I have seen fasciation on a daphne, also! I don't see much point in cutting it out now, at least you have some flowers. i would take that stem out later, though.

Thanks for that. When I do chop - should it be above the union or below; ie down to the next branch?

I would take it low to make sure that it was completely removed.
How long have you had the daphne, Fractal. I thought that fasciation was an anormality in the gene structure of a plant and should show early in its life.

it can be caused by damage to a growth point [apical/lateral meristem] and as the new growth starts the fasciatoion occurs as the cells have been affected. temperature, sap suckers are often cited as causes.

Bulbaholic - The plant is only a couple of years old. Or rather it was bought and planted a couple of years ago. I suspect that it will have been 'in the pot' for a couple of years prior to my purchase of course.

Seaburngirl - It is quite possible that damage was done by our rather exhuberant dog (Whippet). I didn't notice any but still...
