You are not limited to cacti, succulents or narrow leafed evergreens when selecting plants adapted to low moisture requirements. Many plants growing in humid environments are well adapted to low levels of soil moisture. Numerous plants found growing in coastal or mountainous regions have developed mechanisms for dealing with extremely sandy, excessively well-drained soils or rocky cold soils in which moisture is limited for months at a time.

    Indigenous plants, plants that occur naturally in the local environment, will likely need less supplemental moisture most years than non-native species. These species have evolved under the local conditions and usually have well-developed mechanisms for surviving extremes in the weather.
