Definition - What does Xeric mean?
Xeric refers to plants or a landscape that flourishes with very little water. Desertscapes usually feature xeric plants.
Xeric plants require very little, if any, supplemental watering after the plant is fully established. In order to be fully established, most xeric plants require about 18 to 24 months of supplemental watering when first planted.
MaximumYield explains Xeric
Once the xeric plant grows an adequate root system it is extremely drought tolerant. Blue fescue, sage, thyme, and sea holly are all popular xeric plant choices.
Xeric plants have become popular choices for xeriscaping. With droughts becoming commonplace in many parts of the world, xeriscaping is becoming a popular and common landscaping option. By choosing xeric plants, the gardener rarely, if ever, needs to irrigate the landscape.
Mature xeric plants flourish with little or no supplemental water. Xeric plants are a wonderful choice to plant in regions that are frequently hot and dry. The tough, desert-type plants require very little care to survive even in adverse weather conditions.
Cacti plants and succulents are considered xeric plants because they both conserve water as they grow, requiring less care and attention than other plants. Some types of xeric plants can reseed on their own, popping up as seedlings in gravel driveways, for instance, or among other xeric plants.
