Some plants that thrive in heavy, poor, and shallow soils include Michaelmas Daisy (in fact most Asters will do well in clay soils), Helenium, Viburnum plicatum (Japanese Snowball, Weigela, Rudbeckia, Buphthalmum, Solidago, Crataegus (Hawthorn), Forsythia, Spiraea arguta, Salix (Willow), Anemone, Lysimachia clethroides (Loosestrife), Leopard's Bane, Monarda (Bee Balm), Daylily, Foxglove and Prunella. Be sure to mulch the garden with organic matter to help the soil retain moisture and help suppress weeds. If you can dig the organic matter into the soil at the end of the season you'll eventually improve the soil and make it more hospitable to a wider range of plants. |
