to 'lazy' gardeners like me living in my zone
We just moved here and have this huge front and back yard. I have always been what I call a "lazy" gardener. I like plants that flower prolifically over a nice long period of time. If they get really big its even better. If they don't need to be babied, I'm happy (I mean I water and weed and such but don't have time to coddle plants).
The soil is clay and moist. Anything that doesn't like moisture kind of drowns it seems. I see that my neighbors have crepe myrtle, lavatera (rose mallow?), and marigolds. Crysanthemums grow well but don't like the rain in their faces much.
I've done bogs before so know that siberian iris, crocosmia, some daylilies, and joe pye weed work well but am looking for that special plant that just goes nuts with flowers...like the lavatera.
