I found I couldn't keep up with the maintenance of the feeders. It's very hot here, and the worry that the syrup would spoil was just too much.

I grow a kind flower from Mexico called tithonia. The h'birds love it. Also the butterflies. They are easy to grow, at least here in the Midwest US. The plants are taller than I am and have many orange blooms. Here's a picture:

tithonia

I believe the variety is 'Goldsturm,' and I got the seeds from Park seeds. They self-sow but are not invasive.
