Very nice red hollyhock, extremely low maintenance and very drought tolerant. My first one was planted less than 3 inches away from the trunk of a very large doug fir tree. Needless to say, in the summer it gets no rain and absolutely zero water to it's roots because the tree gets it all first. It blooms nicely though, and has been evergreen the past three winters. Now I have about a dozen seedlings that have come up, lucky me!
