can anyone give me advice on how to grow this from seed? I tried just
direct seeding outside in May (in both semi-shade and semi-sun) when it
was part the frost date where I live and not even a peep of green leaf
anywhere. Thanks for any help Jean Delta BC - with a climate very
similar to the southern UK

Meconopsis cambrica germinates better from seed sown fresh. I've got a
patch of mixed Meconopsis cambrica, and at the moment something, which I
assume is Meconopsis cambrica, is coming up like cress.
