I love when plants self-sow. I suppose a tidy gardener wouldn't like the chaos of unintended plants popping up all over, but I always like the surprise of seeing what's going to turn up where.
Today when I was raking leaves off a small patch of lawn near the patio I suddenly noticed the delicious bitter smell of arugula. I then realized the entire edge of lawn was flanked by self-propagated arugula! It made me laugh out loud. Of all the plants I grow in the garden, arugula is definitely the most like a wild weed, and I'm used to it appearing all over the place. But something about it turning up away from the vegetable garden and amidst the lawn was amusing. The rogue Italian interloper. Theme for my day!
