Hibiscus for me, too. I have the native species. I scattered them back in the pasture. I don't have high hopes for germination, it's hot and dry back there, but might as well give it a shot. I scattered some swamp milkweed seeds back there, too.

Prairie Moon has good germination info on natives, here's the page for hibiscus moscheutos (it's under Planting at the bottom of the page): Hibiscus moscheutos Swamp Rose Mallow | Prairie Moon Nursery

My annuals normally reseed themselves. I still collect some just in case: California poppy, larkspur, Chinese forget me not, Marigolds, gomphrena, Orlaya…

I've collected some seeds from a couple milkweeds, a tithonia that had LOTS of flowers, cowpen daisy even though I may get a thousand volunteers, celosia (also will have too many volunteers), verbena bonariensis - same, echinacea Cheyenne Spirit, and some others. I've collected a bunch of seeds from salvia greggii Texas Hardy Pink. I don't know if the seedlings will be hardier than most s. greggiis but there might be some potential.

I just need a very large gardening area with bare loose soil and no weeds. : )

@christie_sw_mo, I often hear about verbena bonariensis reseeding well, however I never seem to have seen any seedlings. Maybe I need to check the seed pods and collect the seeds.

I have a bed that is already covered by small Orlaya seedlings. I will move some to other gardens to show green colors in the winter.

I collected a dozen black gum seeds while out walking and strew them in a flower bed. Two years ago I scattered hackberry seeds in that bed and got four seedlings so I'm using the same sophisticated technique.

@forever_a_newbie_VA8, do you currently have VB in your garden? If so you should have no problem getting them to reseed w/o any help from you :). It is my experience that VB will successfully reseed (with abandon) in areas in which you can easily the ground i.e. dirt. I say this as I have tried for years to hand sow VB seeds in later Fall in a location completely covered by wild grasses and the like and I have never see a single VB the following season :(. And yet in this same place I can get triloba to seed successfully.

(@Jay 6a Chicago I am way impressed with your seed organization....well done)

Each Fall I actively collect seeds from

• Ipomopsis rubra (biennial)
• from a variety of angelicas (biennial)
• verbena bonariensis

Jay seems to take the prize for seed collection! :-) Impressive!

I forgot to add, Lunaria. I don't collect the seed because it reseeds so well for me. It comes back every year. It also drops the seeds and the seedlings establish in late summer early fall, all ready to go the next season.

I had Verbena bonariensis and lost almost all of it last season for some reason. But when I loved a different plant from that area to another, I noticed a VB seedling popped up at it's base the next season. I can't remember if that reseeded for me, or if it spread I wonder if it did both?

Porkchop, Thanks for that link to PrairieMoon Nursery. I've bought both seeds and plants from them in the past.
