Just wondering given its august if I can plant or should I just wait until next spring?

Why would you wait? I think Yucca rostrata is hardy to zone 7a or something like that...and better to get the roots into the ground where they're insulated. Roots are the most sensitive part of a plant to cold, so the insulation will help it in the event of super-cold event. You still have some time for root-establishment and top-growth as well. I think the more important thing is to make sure in a wet, humid climate that it would be prudent to plant it in a somewhat raised position, in the sandiest substrate you have available, for maximum oxygenation of the roots and excellent drainage. Avoid planting in a "sump," in a block of heavy surrounding soil where water would accumulate. Otherwise it's a very, very hardy plant. It's even planted in the UK, so obviously it's a fairly adaptable garden subject!

Planting now = ..at least.. 3 months for it to start putting down roots before it slows to a crawl / takes a nap -growth - wise- thru the coldest portion of winter where you're at..

Only thing that might make me wait until spring, if i lived in a climate like yours? ..if i were starting with a plant smaller than a 1 gal.

Would look through this 👇 thread, and other Y. rostrata related threads started by / incl. thoughts from @teddytn

Think @N8ALLRIGHT is growing one in K.C. as well.

Soil wise? Only thing they don't like is heavy / mucky clay that stays soggy. Chunkier / Better it drains = perfect.

Yep, I've got a rostrata in zone 6b. It's planted on a hill with lightly amended soil and clay. It's unprotected and doing well. I did dig a small channel and filled with gravel to help drain away any moisture over the winter. My best spot is already taken by a yucca schotti so I was a little apprehensive on its placement but it sailed through it's first winter w/o a hitch. Where you are in zone 8 I probably would plant it now but I'd make sure it was in a well draining spot with full sun. Assuming it's not a little plant,if it is what's it hurt to keep it inside for the winter . Mine was planted from a 5gal in the spring.

You guys are so right, I would rather put them in the ground and give them time now at least, I really don't want to have to take care of to many potted things this winter but that being said I'll have to plan where I'll put them. I have lots of sand so moisture is never a problem but that also sucks for my other plants since it requires so much more waterings for palms and ect 😭
