Kind of yellow-tipped - really striking - couldn't find anything like it on line.
The "yellow tipped" appearance is typical in autumn. It could be any one of many cultivars of Liriope muscari.
Hi, thanks - I took these pictures in August (zone 7A) - I also have several liriope cultivars and they don't get a yellow-tipped appearance, they are all evergreen in my zone....
I might also suggest a couple other things...one possibility is sunburn/windburn....and the other is possibly Pythium splendens, a fungal infection...it will cause leaf tips to yellow and eventually rot the plants roots. There is also Phytophthora palmivora, the common root rot fungus, but it starts at the base of the plant rather than the tips and would be very obvious.
I agree with moon, looks like some sort of disease, cultural issue, etc vs how it ought to look naturally.
Thanks everybody, too bad because I found the yellow-tipped appearance really striking. But this explains why I couldn't find any cultivar that looks like it. Kind of weird though that a liriope would be diseased or damaged by weather, they are so tough. And that the disease would be so uniform. I'll have to take another look at it now that it's cold. If I get to do that I'll take a pic & put it up here.
That may be one of the cultivars that does better with afternoon shade and what you see is sunburn...that would account for the more uniform coloration.
Now that's a thought. Interesting that I kind of dig the sunburn if that's what it is.... :-) Going to try to take another look at it tomorrow & get another picture.
