I do so wish that Michael will not be encouraged too much in his search for
alders that will feed the planet "if I can find one with big seeds"

I have found alder seeds which are close to the size of rice grains. I
am now looking for bigger. It will be a starch belly-filler like
wheat, potatoes or rice.

Or maybe I am totally wrong and that's the way to go.

This country has been unable to feed itself since the repeal of the
Corn Laws in 1846. 40% of this country's land is "upland", unable to
grow cereals.

People help me because they have the knowledge and want to give it to
somebody who needs it. What possible harm do you think I might do? If
it doesn't work out (and it is a difficult project) then there is no
outcome, but if it does work out, what harm?

"Treason never does prosper, why what's the reason.
If treason does prosper, none dare call it treason."



Nobody backs a lost cause.

You say seed the size of rice grains, but not the same weight I'm sure.
BUT
The question I have is
How do you expect the seed to be picked/gathered.
It's fiddly work collecting a quantity of Hazel nuts and they are much
heavier than alder seed.
