Mark S sent me a little seed some time ago from miniature forms of his hostas and I was quite disappointed that only one germinatated though all the seed looked good. Anyway, the one has been growing nicely over perhaps 18 months - I can't remember when it came through - and I've been meaning to take a picture for some time. Today I did and it's not easy to see but the leaves are slightly lighter green in the centres than around the edges.
Then I noticed that there was another, different leaf under one regular leaf and pushed aside the top one to photograph this white-centred leaf. Now I'm not sure if I have one or two as all the foliage is coming from a very tight spot in the centre of the plant. The white leaf is just about 2cms long and for comparison, the label is 5cms across the top, so whether 1 or 2, this is/are very small and neat.
