swimming purple and white are my first choices! I only choose anything that flowers in purple, white or pink. I am very strict about this, but I do welcome all shades of green in foliage. I don’t do orange, yellow or red, though I do like them in other people’s gardens.
purple I am very much a novice gardener, so take anything I say with a pinch of salt! I also get very excited in April/May each year, and that’s when I start buying everything I see, so my garden very much reflects this. Come July last year, all I had in flower are salvias, cranesbill and hydrangeas! I have a list this year of things to buy for July-September.
