An unidentified species of grass - luckily very shallow roots, so easy to pull and drop. Rhubarb - it's winter here in the Southern hemisphere, and it's supposed to be dormant, or at least slow down. However, neither of the plants got the memo. Rampant self-sown loose leaf lettuce. Everywhere, but not in the garden proper. Madder, the colder weather doesn't seem to have slowed it down much, and I'm wanting to harvest the roots.
On the other hand - total failure with the snow peas. They are supposed to be planted round about St. Patrick's day - only one sprouted, and something ate it!
