RAH nailed it on the head. Stick with native plants and succulents when every you can. If focusing on honey production by planting heavy floral plants, best to find the native herbs that suit your needs. Introduction of exotic plants that are not within the 5 surround states can cause detrimental effects to the surrounding habitats, due to possible invasive plant species without herbivores to consume them, or the requirement of herbicides and pesticides to control the nuisance. Research, and tell us what floral species you would like. I'll ask the biologists and habitat management here about the possible natural toxicity that the plants will produce to harm the existing aquafauna of your lower pond during run-off.
