Hi Alisdair,
yes, Lady Bea is a "good doer"! It's the only one of the doubles that actually increases for us in this garden.
Here are a few more:
Galanthus elwesii in the rock garden, this one has seeded about!
Galanthus plicatus
A late form of Galanthus elwesii only just coming into flower now,
cheers
fermi
