I enjoyed your article on one of my favorite plants. There are so many tropical hibiscus now that growers are continually cross pollinating them. It boggles the mind trying to collect them. I am getting more "picky" now, and pass up any hib that's leggy. I like the more bushy ones.
I do love the ROS also because they need very little care, are fairly drought tolerant, and surpisingly, the deer leave them alone in our yard.
