Peonies are coming into their full bloom! These gorgeously large, fragrant, and delicate blooms are the goal of pretty much every gardener. True, the blooms can be fleeting, but the plants are easy to grow! I use four types of peonies in my garden, all of which I find incredibly beautiful: - fern leaf (paeonia tenufolia) - herbaceous garden (paeonia lactiflora) - itoh (paeonia intersectional hybrid) - tree (saxifragales) Fern leaf peonies are the easiest to bloom and stay small, around two feet.
