Peonies are one of the most popular perennials. If planted properly, they will bloom faithfully every spring. Tree peonies open earliest, at least two weeks before others. Peonies appear in all colors except blue. So far this is my collection of peonies.
P.S. Because we won't be having ikebana classes in September and my orchids usually bloom the least this time of year, so I am publishing my Garden Series.
