not too likely there are any with four leaves in there but they make a lovely ground cover in the garden.
occasionally it'll put out clovers with red leaves
the clover may not be lucky but this guy was...
i found this little guy (a pacific tree frog---never once have i seen one actually in a tree) hanging out in the end of my watering wand. he's lucky i found him before i attached it to the hose. he was kind enough to pose for some photos before exiting the wand.
