2000 Q. I am trying to find a source for peonies in Northern California as well as the optimum garden conditions for these beautiful plants. Both types are available at local nurseries.
Herbaceous peonies grow from thickened, tuberous roots.
They bloom well only after a period of pronounced winter chill. Winter cold and summer heat are not problems, but the flowers do not last long where spring days are hot and dry. In such areas, choose early blooming varieties, and give plants some afternoon shade and ample water. Feed established clumps like other plants, and provide support for heavy flowers. Cut off stems carefully just below the soil surface in fall, after the leaves turn brown.
