Yes, I've heard the same thing about figs. I took mine out of a pot for which it got too big. It's now in open ground and I'm wondering whether, even at this late stage, I should sink some upended paving blocks around it, to confine the roots.
I'll think some more about lilies. Because I am a plant snob have a rigorous black and white colour scheme in that part of the garden, I don't plant coloured ones. Most lilies are fine in shade. My favourites are lilium regale, because of the height and scent, but I do have some (can't immediately think of the name) which are purportedly black but are in fact dark maroon. I'll inspect them tomorrow to see if they still have their label. The thing to bear in mind is that very dark flowers can become lost in shade, which is the drawback of my B&W planting scheme once the tree that shades it is in leaf.
Some hostas are more slugproof than others - go for the ones with more leathery leaves as the tiny delicate ones can be chomped to nothing in an evening.
I'm worried slightly that Bertha is telling me in a very kind and gentle way that I should stop imposing my gardening obsessions and prejudices on others, so I'll stop now!
And Lexi is right, of course. This isn't (I thought) a thread that anyone needs permission to join. The more, the merrier!
