OK, I will, thanks for the invite! Dave's Gardens has so many forums that interest me. I bet they would really love Bob's blooms. I'll try and get some photos of his garden too. He has over 100 kinds planted this year. Dahlias must not produce much nectar -- I've never seen a hummer or many butterflies visit them.
Most of you are probably too far north for this, but since last fall I've had hummingbirds glued to my porterweed. I don't have any feeders up, but I have a lot of butterfly-friendly plants. Nearly every morning when I walk out the front door I scare the hummingbird away from the porterweed (he comes back when I "disappear" into the car). I know I have at least two because I saw them once at the same time. Also, this past weekend I saw a hummingbird at the USF Botanical Gardens and it was eating passion flower which surprised me.
Here's a pic of my hummingbird. I had to sit in the passenger side of my car and stake him out for about twenty minutes to get this picture. Suckers are fast!
I checked DG Plant Files about the Porterweed. Porterweed grows in zones 9a to 11 http://davesgarden.com/guides/pf/go/2392/ so we would have to treat it as an annual, which is still a consideration. I usually grow Pineapple sage, Salvia 'Coral Nymph' and a few other annuals in our hummer garden too. I don't think I've ever noticed Porterweed for sale around here, but I've never looked for it before.
Agastache is one of my favorites (hummers too, of course!). For some reason ours is not reseeding like a weed, like it usually does. I'm thinking the goldfinches and all the birds are eating every single seed lol. Luckily I had shared some with our gardening neighbor a few years ago and she was nice enough to dig up several pots full that I hope to get in the ground later today :)
