This marigold looks as though it came up in the flowerbed from last year.
Only there were no plants of any kind in that bed when I moved in last August. I'm pretty sure that plant hopped out of the pot next to it, which is one I brought from the old house that was rented. Three pots sprouted little marigold seedlings after I got them here. This one must have adventurously leaped for the ground, where it could grow bigger and more healthy than its sisters.
