Here's a brief list of some of the natives I grow in my tiny 'prairie' here in Oklahoma that naturalize nicely and are adapted to our sometimes extreme conditions:

Cowpen Daisy. Nice tall sturdy plants with blue leaves and lots of yellow blooms late spring to freeze, naturalizes nicely---annual.

Liatris, they self sow as thick as grass.

Annual or perennial Gaillardia. Easy, Long blooming, tough, naturalizes nicely.

Prairie grasses--Little Bluestem, Sideoats Grama, Blue Grama, Indian Grass, Switchgrass, Big Bluestem, Split bluestem, Purple Three Awn.

Ratibida columnifera---Mexican Hats. Love them, long bloom time, self sow freely.

Maximillian Sunflower, spreads by underground runners, likes ditches and moist areas. Actually, I took this one out due to the limited size of my area but its a good one.

Azure Sage, short fall bloom time but nice.

Veronia lindheimerri --Silver Ironweed

Leadplant-- Amorpha canescens

Heath Aster--forms large colonies

Some of those are very modest spreaders like the salvia azurea (in my experience at least), reseeding was pretty minimal for me in OK too. I never saw Leadplant spread, heck I couldn't keep it alive (*lol*), despite a large individual/small colony directly across the road from my property (but it grew on a ridge..where my property was lower and wetter).

Klunk, not that you would want to, but sawtooth sunflower-Helianthus grosseserratus-is just such a native spreader-too aggressive in some situations, but able to colonize big spaces for when that is needed. Just one idea, but a good one.

Barron, I was overrun with seedlings from one Azure sage the first year I grew it. Its not an impact plant but it was a generous seeder here, it got quite tall, at least 7ft tall if you held the thin branches up and there was lots of branches twisting around in all directions from not being able to hold itself erect in good soil. I moved mine to a dry lean spot down by the street and it is much smaller and well behaved there.

Along the Kansas roadside where I got my rooted start most of the patches of Leadplant were at least 12 or more feet wide growing for miles all along the rural side roads and they were blooming heavily. What looked like a small separate plant was actually connected underground to the others so it appeared one plant keeps sending up new plants from roots eventually forming a large colony. The roots are very tough. The effect was dramatic because they stand out boldly in stark contrast. It probably takes a long time to get to that point but well worth the wait. The soil looked rich and fertile in some places and pretty steep and rocky in others. They like average to dry soil. I can certainly provide dry. In wetter areas you'd probably want to plant the green type, Amorpha fruticosa which Klunk listed.

Down here I have quite a few Turk's Cap Malvaviscus drummondii (Texas native). This year I have enough berries full of seeds to plant a field of them. Its a good impact plant further south that will grow & bloom heavily in full sun to full shade. Drought doesn't seem to faze it and we always have to factor that in down here because if a plant is not tolerant it won't last in the long run-- one hot dry summer is all it takes.

Yes, fruticosa started spreading and didn't seem to want to stop (all from underground as you mentioned). I got a lot of Turk's cap seeds too...usually I just get two or three, I got a couple dozen this time off my one. I've never had an issue with too moist soil for the malvaviscus either.

Should have said-Helianthus grosseserratus is suitable for moist areas. Not a dryland sunflower.

My bad, when I talked about Blue Flase Idigo I meant

Baptisia australis.

I also have planted Leadplant. I never spread but grew into a decent sized plant.

xexmania, prairie agalinus, Texas Persimon, several of the wild asters, Cherokee plum. Artemisia ludovinciana, Consumption weed.
