Summertime nectar-producing flowers in the South
I've been researching beesource and other areas trying to determine which nectar-producing flowering plants do well from July through September in the Deep South. So far I've come up with Anise Hyssop, Borage, Caryopteris and White Salvia as potential candidates, but would definitely appreciate any experience/feedback you may have growing flowers during this time period as propogating these varieties, especially the Caryopteris and White Salvia, from seed takes some initial greenhouse-style procedures from everything I've been reading. I'm up to the challenge, but just want to make sure it's worth my time.
I have four 300-foot irrigated rows I just tilled up to use as a pollinator habitat area. I have initially planted a seed mixture of 5 clovers (yellow and white sweet clover, Ladino and white dutch clovers and Alsike) as a ground cover, but would also like to add some bush-like plantings to provide nectar sources during our hot summer months down here. All 4 of my rows have full sun.
Any thoughts will be greatly appreciated.
