NWF's Keystone Plants by Ecoregion - a great resource for selecting plants for your garden/habitat (North America focused)

This is a great resource I've used in the past to help plan out plants I'd like to grow in my pollinator beds. It lists genera of plants that are known to support large numbers of pollinators and/or birds separated by North American ecoregions. Select your ecoregion to get a pdf with your local keystone genera. From there, pick out some species from those genera that you like and are native or near-native to you. I use BONAP (http://bonap.net/NAPA/Genus/Traditional/County) to help pick out species once I have genera I'm interested in.

Hope this helps!
