Delphiniums are a summer-blooming perennial that provides truly blue flowers on long flower stalks. The standard varieties often need staking, so are a little more work than some of the plants on this list…but they are such a beautiful blue, I couldn’t leave them off!

Delphiniums also don’t like hot weather so tend to do better in northern climates than in the south.  But I love them so much that in my South Carolina garden, I plant them as annuals in the spring (they always die in the heat of the summer).
