Many plants appreciate limestone soils, so you’ll find a good number of chalk-loving plants. Furthermore, since they retain water less well than other types of soil, limestone soils have the advantage of warming up quickly in spring. So, if your soil is alkaline, many gardening options are available to you! To help you in your planting choices, here is a list (partial, of course) of plants for limestone soil.
