It is a begonia. Probably Begonia grandis. It is a very common one and spreads so easily.

When I just googled 'hardy begonias in mo' the only begonia hardy in Missouri.is Begonia grandis.

"Begonia grandis, commonly called hardy begonia, is the only species of Begonia that is winter hardy to the St. Louis area. It is a monoecious, tuberous-rooted, clump-forming perennial that typically forms a bushy mound of foliage to 2’ tall on branching stems. Large, obliquely ovate leaves (to 4” long) with cordate bases are medium to olive green above and reddish green with red veining beneath. Male and female pale pink flowers (to 1” across) bloom in pendent clusters (dichotomous cymes) from July to early fall."

That's a hardy begonia. It spreads readily if it likes its location. It prefers a moist, part shady location. Mine are growing on the northeast side of my house. They disappear after first frost and don't emerge from their winter rest until May in my zone 7 yard.
