I love this little yellow daisy annual (Pectis sp.). I lost it when Mexican gardeners helped me--it was a weed to them and was removed. I had to transplant a few seedlings back in the garden and let them go to seed, to get it established again. It seems to sprout especially well along the brick border which stays wetter after rain or watering. I like the irregular edge it gives to the paths. Now I train gardeners (when I'm lucky to find someone) to pull only the grasses.
