Flowers for Acidic, Clay Soil

amethyst dreamI need to get some vibrant planting in for a late May showing in the garden. The soil is clay and acidic. My preferred shades are white and dark purples/blues. Any ideas would be very welcome.

Best, Anne H.

Answer: It appears you live in the UK, so I am going to assume your weather is a little more temperate than on this side of the pond.

You do not mention if you are looking for full sun (at least six hours) or shade, so please check the sun requirements for the suggested plants.

One of my favorite plants is Bougainvillea, which is available in several vibrant colors. It is considered a tropical, so it would need cold weather protection. There are several other options in our Flowering Plants category. Check out our Annuals: Calibrachoa, Osteospermum, Lophospermum, Bacopa, and Lobelia. In the Perennial section there are lots of options like: Agastache, Baptisia, Centaurea, Delphinium, Digitalis, Eupatorium, Echinacea, Liatris, Lupine, Nepeta, Penstemon, Perovskia, Phlox, Salvia, Geranium, and Veronica all have varieties in your color options.

Happy gardening,

    Many thanks for your reply – sadly as you are based in the States I can’t really order from garden harvest supplies however I have taken up your suggestions and bought some delphina, digitalis and lupins. Lobelia and geraniums are on the list however not available for planting for another few weeks (although in the South of England we live in a valley which seems to slightly delay spring…).

    I have also bought some sweet peas which I will be training up through metal obelisks and some clematis to form a backdrop to some olive trees in a garden sitting area.

    As the garden is just over half an acre in size we have sun & shade to consider – part of my desperation is because I have been asked to open the garden as part of the horticultural society’s garden gate event in early June.

    Let me know if you are interested in seeing some photos when the planting becomes established.
