Magnesian Limestone Gardening

Magnesian Limestone Gardening

Durham Botanic Garden 1.3.09

Magnesian limestone grassland is uncommon in the UK but supports a wide range of plants and invertebrates. The dolomite or limestone has weathered to form thin lime-rich soils on which unique wildflower meadows have developed.

Looking at natural sites can give you ideas for your own garden. Early spring is a good time to visit when the cowslips and early orchids are in flower. By mid july the meadows should be at there peak with flowers and insects. Depending on the ph of your garden soil you will be able to plan where what and how to grow Lime loving plants. My natural clay soil errs towards acidic so I have long struggled to grow thymes, saxifrages and scaboius but I have happily grow Rock Roses. Having seen the plants in situe I can now modify my own garden conditions.
