I have about 5 of these guys growing in my back yard and have no idea what they are. If anyone know pleases let me know.
Looks like a tiger lily .... From here
Pretty certain it's not a Lily. It could be lots of things. Flowers will help id it more accurately. One possibility is Epilobium/ Chaemerion angustifolium. But I am sure there are other similar-looking, likely weeds in your area which I am not familiar with.
Does it have a hard, woody stem? Not that I would know what kind for CA, but looks like an infant tree to me.
