Narcissus 'Grand Soleil d'Or' - 2013

Andrew, what is the plant with the plum foliage?

Mouldy - it's purple sage (salvia officinalis 'Purpurescens' to give it it's Latin name). As the narcissus is not one of the hardiest varieties, the sage gives it a bit of protection through the worst of the winter weather

Thanks Andrew.
It looks fairly sturdy & the leaves look quite velvety.
Is it edible, for humans, I mean?

Yes, you can use it in the exactly the same way as ordinary sage

Excellent!
Good looking & good eating. Lol.
