I can't seem to find a chart describing the mixture of the various grass seeds in Black Beauty Ultra Mix and their percentages.

Jonathan Green Black Beauty Ultra Grass Seed MixtureLot: BBU-10-2; Seeding rate: 5.0 lb per 1000 ft2% by weight Cultivar/Species 29.70% ‘Dakota’ Tall Fescue 29.65% ‘Taos’ Tall Fescue 19.75% ‘Tombstone’ Tall Fescue 9.85% ‘Blue-tastic’ Kentucky Bluegrass 9.83% ‘Frontier’ Perennial Ryegrass .

Is it good for Denver, Colorado area?

It is. TTTF with Bluegrass. Stays green with 1- 1 1/2 inches a week. I’m in 80015 Great cool season grass

can the black beauty seed be put down over an existing lawn?

As I mentioned in a previous review of this product the product didn't germinate(grow) in two attempts to overseed an existing lawn under ideal conditions. I even took some seed and placed it in a seedling tray and it didn't germinate either. I attempted to reach out to the company twice prior to posting the negative review to provide them with an opportunity for a response/explanation and never received a response.

Would this grass be good in Missouri

I have no reason to believe why it should not grow there.
