Peonies and Oriental Lilies
I was thinking about how lovely these oriental lilies looked next to my peonies when I decided that might be a great topic to share - companion plants for peonies. Some other plants that I like to plant near my peonies are spring bloomers like irises, if you want to get some complimentary blooms. Or if you want to add some color to accent the gorgeous green summer foliage of peonies, tall summer blooming bulbs like lilies and gladioli are perfect complements to the medium height foliage of the peonies. I like to plant the lilies in between the roots of two peonies and maybe slightly behind. This has two purposes. One to give the lilies some support with the peony foliage in front of them, and two to hide the emerging lily shoot from the deer! I can't say this works all of the time, but in my yard it does work most years! I think that's the only reason I have lilies and hostas in my yard (because I surround them with peonies and hellebores!)
Peonies and Fairy Roses
Another summer blooming option for a companion plant to peonies is roses. One of my favorites is fairy roses. They're almost like knockout roses, except miniature. They bloom for months, and have several color options. I also like to plant daylilies near my peonies, just not too close. Daylilies form large storage roots underground just like peonies. So they would definitely be in competition if planted too close. Hellebores are another great companion plant to peonies, blooming at almost the opposite time of the year when peonies are in their rest cycle of winter. Hellebores would provide nice companion foliage during the peony bloom season and while they are going dormant, and lovely blooms while peonies are still asleep. These two should not be planted too close to peonies since they develop an extensive root system. So there are lots of plants that do well in the same light and soil conditions as peonies to keep the interest and color coming all year long!
