Lirope are prone to a couple of fungal problems, especially if they are watered overhead, watered too much, or mulch is applied right up to the base of the plant. (Always keep mulch back a few inches from the base of all trees, shrubs and other plants--it encourages disease and insect problems.)

We can't say for sure from the photos whether the symptoms are of anthracnose or crown rot. Please read through the following Extension page and look at the photos: http://www.clemson.edu/extension/hgic/plants/landscape/groundcovers/hgic1108.html

Be sure to cut these back in late winter-very early spring and remove all infected plant material so spores don't get on next year's clear new foliage.
