Growing variegated liriope is relatively easy and can make for a gorgeous accent to any yard, granted it is planted in the right environment and given the proper care. First and foremost, this plant will only grow in hardiness zones 6 through 10. It cannot withstand frigid temperatures and, if placed in direct sun in zones 9 and 10, variegated liriope can suffer severe damage, ranging from leaf burn to yellow, discolored foliage. Because of the hardiness of the rhizomes, this particular plant can be planted all year round without any negative side effects occurring. However, if living in an area where you experience frost, you should wait until the ground is easy to work with, more so for your own benefit than that of the plant.
Although it is called Aztec grass, this particular plant cannot handle foot traffic. Therefore, when choosing a site, find an area that will not be used for general walking. Variegated liriope works extremely well as a border plant, especially for edging around sidewalks. It is preferable that you select a site that will receive full to partial shade. For this reason, it works well if planted underneath trees or in the shade of shrubs. It is also important that you find a location where the soil will drain well. Being moderately drought tolerant, it cannot withstand wet feet. You can check the drainage of your soil by digging a hole at least 6 inches deep and filling it with water. If it takes more than 4 hours for it to drain, you will need to amend your soil in order to allow for better drainage. Mixing in 3 to 4 inches of compost can help to increase the rate at which water passes through. For best results, you should try and plant it in soil that is clay, sand, or loam. It will generally grow in either alkaline or acidic soil, so you shouldn't have to amend or alter the pH level prior to planting.
Although it is moderately drought tolerant, in extremely hot and arid conditions, it is required that you water it regularly. The soil should never be allowed to completely dry out, though it should never be sopping wet either. If your area receives less than an inch of rain in a week, you should consider providing it with additional water.
Under normal conditions, variegated liriope does not require additional fertilization, though added amounts of nitrogen will help to improve its coloration if it appears to be dull. If you notice that the plant is beginning to suffer as a result of overcrowding, you may need to divide the rhizomes. This will generally be required after 3 years, when the plant has become fully mature. If adequate spacing is given when the plant is initially planted, it could delay the need for dividing.
Though variegated liriope doesn't provide any bright and conspicuous flowers, it does work extremely well as a ground cover. Add that to the fact that it is relatively maintenance free and you have yourself the perfect go-to border plant.
