Dandelion is a widely distributed perennial broadleaf weed found throughout California, except in deserts, to about 11000 feet (3300 m). It consists of a complex of biotypes that vary with environmental conditions and is a common weed of mountain meadows and turf, especially in southern California. Because dandelion contains high amounts of certain minerals, it serves as a complement to pasture forage for livestock……YES it’s safe for the torts!
That's what I thought for the first plant, is it a dandelion? But I see the slight hairs at the start of the stem, and I don't know whether dandelion has those hairs or not.
Funny how I try to plant dandelion a lot of time and keep failing, and suddenly one is growing in the garden... Must be one of the thrown seed got there by accident and grow if it is really dandelion
