Plants, Flowers and Trees that will Grow in Alkaline Soil

These plants will grow and thrive in alkaline soil Soils in arid climates tend to be alkaline, with a pH factor of 7.0 or higher.
This is caused by the high percentage of lime (calcium carbonate) in soil of these regions.
The main problem associated with alkaline soils is that certain essential nutrients, particularly iron and zinc,
become unavailable to the plants.
If the soil is mildly alkaline (pH 7.5) you have nothing to worry about, however, the higher the pH, the harder it will be for you to find appropriate plants that will survive in your garden...
