Re: brain hurts from too much input!
My bees forage home depot's nursery and they've done ok. Seriously, with nothing around me but dead brown bermuda grass and dallis grass, I plant for the bees, except for my small front yard of st-augustine (I watered my oak and vitex, the grass happened to live) and my burnt up bermuda back yard..
I ordered from Stock Seed and got Crimson clover seed for about $4 a pound, I refrigerate what I don't use, use it as a border around the garden and the bee lot, it bloomed first year, I had a lb, probably have a 15 year supply. I use a fairly high end Texas wildflower mix, paid $30 retail for 2 lbs about 7 years ago, but I'm still planting from it. Left side of my crisper is obviously full of seeds. I planted vitex and rose of sharon bushes this fall, to go with what I already have. Rose of sharon isn't the bees favorite (vitex is) but in my part of the world, they like rose of sharon just fine. They love the wildflowers, I have a eunomys shrub with some good smelling blooms, a big china berry tree, a huge elm that should start blooming soon, cherry laurel, and a lot of abelia bushes that are pretty popular, blackberries, grapes and my normal veggie garden. For 1/3 of an acre surrounded by range land, I have a virtual garden of eden for bees and hummingbirds and other things that like flowers. And my ponds provide water, and water lily and bog plant blooms to work..
Now is the time to buy shrubs. Any nursery with any left starts dumping them on sale just before a freeze. I have a small greenhouse full from the Lowes pre-freeze dump, got about $200 in plants for $40. Those aren't dormant so I will hold there til spring.
What bees do NOT like: Turks Cap. It's red, hummingbirds love it, bees could care less. They aren't wild about lantana, and my roses are somewhat neglected.
Live and learn. EFB vaniquished and sterilized. Harvested honey. Now heading off the fall swarms.
