Other types of fescue are forage and fine. Fine might be a type of turf type, but the forage type is different. It comes in brown bags at the feed store. Farmers use it to stop erosion if not for forage.

There re are different cultivars of turf type tall fescue. Some are more fine bladed than others. Some exhibit more lateral growth than others, but all TTTF is bunch.

Most of the if box stores will sell TTTF but label it as Tall Fescue. For example, Scott's Turf Builder Tall Fescue is comprised of all TTTF cultivars. Similarly, Pennington's Smart Seed Tall Fescue is all TTTF. I think this answers your question.

When in doubt, check the label. If it lists Kentucky-31 or Alta, it's not TTTF. Likewise, if the tall fescue marketed as "endophyte free" is likely NOT TTTF--- rather, that is more than likely a pasture type of Fescue (cattle and horses have issues with endophytes).

note-

Tall Fescue and Turf Type Tall Fescue are more similar to each other than they are with other fescue types, e.g. Fine fescue, hard fescue, sheep fescue, red fescue, blue fescue, etc.

Thanks all. Yes I guess I'm still a little confused as to why they would put a "bunch growing" grass in a mix. I thought mixes were derived as such so the grasses would play nicely and coexist with one another. I like the idea of introducing TTTF as this seems to be potentially drought tolerate in both sun and shade. But not if it takes over and causes patches among an otherwise mix of KBG, rye, and fine fescues (chewings, creeping red...)

some of you have suggested I check the lablel - I have but this doesn't help me which is why I posted this thread :) When I google the above Pennington Tall Fescue cultivars, little information comes up that actually helps to answer my question. I'm sure it must be TTTF, but still - does this mean it will blend in nicely with my existing mix, or stand out like a sore thumb??

The cultivar mix changes every year, that's why that white tag is on the bag & there's no consistent data online.

Fwiw, Pennington sells a tttf/KBG mix. So does Scott's. They selected the cultivars based on what they think blends well.

If you want uniformity, don't overseed at all. Your KBG will spread around to fill in everything (in the sunny areas). In the shade spots, you couid oversees more KBG-PRG-FF if you notice it thinning out. The FF will probably dominate there.

I think I like that advice, owlnsr!
