I keep trying to add white in and haven't found a good solution to it. I DID plant a white phlox this year, if it does well I'll look into more and taller versions. I like some pinks and reds together, but this monarda I have is just a little insipid... not sure what one it is. So far all I've seen on it are bees... kind of expected butterflies and hummers to be flocking to it... maybe they just need more time to find it...
Also need some plants to provide a different texture and focal point from all the little agastache, salvia, etc. A canna would be perfect, but this is a butterfly garden and I don't know that they're appropriate
