Plants for Alkaline Soils
Soils that are derived from limestone or those overlying marl favor the growth of certain plants. A neutral reaction may be satisfactory for some plants, but the addition of lime will increase the alkalinity that can enhance their health and well-being, not to mention flowering. The following list, while biased toward warm climate plants, has many suggestions for plants that thrive in more alkaline soils.
