freely self seeding, I have land cress, lambs lettuce, rocket,
dandelion (:-), miners lettuce, chinese mustard. The joy of these is that
they are pretty hardy and produce salad leaves in very early spring, when
there's not a lot else around. If you have the odd cloche you can
transplant some seedlings and cloche them to even earlier salads.
All the above freely self seed around the garden - you have to leave some
to seed, and be careful (not) weeding.
