Aren't they beautiful.
I have just rescued a few as we are digging up a border which is full of them all self seeded, but I know in a few years they will be back again. We have to rebuild a wall and there is nothing for it but to dig them up. Aqui will be cross with me I'm sure! I feel quite sad but they are all self set so will be back, especially if I shake all the seed heads on the new border!
Perhaps if I buy a couple of the new pretty ones and add those too we will have even more permutations of colour and shape.
