Seen on a walk at a local park in Twin Falls. There were quite a few of them growing along several streams created by springs coming out of the side of the cliffs.
First a pic of the flower spike.
Next the plants in situ.
Last another location where the plants grow near this waterfall.
Yeah, that is what we want our back yard to look like. Problem is it will take a LOT of work and where the water runs year round some negotiating with the neighbor.
