Well said
Elders are funny things. The old Scots rhyme for them is very descriptive, and folklore is rich in tales of the tree and the hag that lives in/ protects it.
However, every tree is different. They all smell different, while still being unmistakeably Elder. Some smell sweet, some smell of cat pee
Some taste sweet and others taste almost tanniny.
I usually advise folks to have a wander and a tiny taste of as many trees in their locality as they can, that way they can suss out the tasty ones for collecting 'before' they get caught up in a hurried gather when they all ripen at once.
I use two trees for flowers for drying, and the flourish stays white from them, and the tea (or cordial) is very sweet and perfumed
But I try to get fruits from a different tree since that one produces big sweet, almost blackcurrant sized berries.
The fruits from yet a different tree give me deep rich dyes.
As I said, all different.
cheers,
Toddy
