Description:

According to arboretum labels, this area is supposed to be either White Willow, (Salix alba) or Almond Willow, (S. triandra).
But:
White willow has smooth yellow/green shoots, reddish hairless buds.
Almond Willow has smooth shoots, yellow/green hairless buds.
Anyone know which willow has finely hairy, almost downy shoots and buds?

Why, Dirk?

Can you please give some info as to why you are so certain that it is white willow?

I'm not questioning your ID, I am asking for some pointers to help me agree with it, please.

Hi there

Just a combination of things, e.g. colour + indumentum of twigs, colour, shape + indumentum of buds. I have some experience with looking at willows during (poor birding-) winter(s) and one can learn to ID lots of them then. I'm confident that this is S. alba: in S. x fragilis (the one and only other contender) - formerly S. x rubens - buds and twigs are never thát hairy (and buds have a different shape).
