Birdfeeding: Friends of a Feather Flock Together

I made a post about landrace sunchokes, including sources where to buy the tubers or seeds.  These are sunflowers with small high-oil seeds and edible roots.  Mine grow 10-12 feet tall but there are dwarf varieties half that size.  They put out many palm-sized flowers that basically turn into living birdfeeders in late summer.  Note that sunchokes are self-sterile so you need either seeds, landrace tubers, or a plot with lots of diverse cultivars in order for them to set seed.  Mine are mixed landrace that rain seed everywhere and have birds all over them.  :D  If you have a large sunny place, these are a great choice for a native wildflower to attract birds.  Oh, and they're droughtproof.
