lovely! Myself, I am very into this idea of a garden growing itself without any efforts. at my summer place each year I put a load of efforts into erasing different weeds (dandellions and snyt, to name a few) to have others growing freely ;=)
@nikv, you may enjoy this stuff, me thinks.
NB. are you in the know of 'Succulent growers' community? would be a perfect niche spot for a post like this, me thinks.
