6 Reasons Why Peonies Should Be in YourGarden

  1. Peony plants are so long-lived that it is commonly said that peonies will outlive the gardeners who plant them! Note: They will not bloom in their first year but once established,peonies may bloom for 100 years or more with little or noattention.
  2. Peonies also thrive almost anywhere in the country. Many varieties can even survive a Zone 2 winter (that’s a low of -50 degreesF).
  3. Even when they are not in bloom, their dark green, glossy foliage and shrub-like appearance make them handsome focal points in thegarden.
  4. Peonyplants are virtually pest-free—deer and rabbits don’t like theirbittertaste.
  5. Showy and fragrant, peonies will also make excellent cutflowers!
  6. While September is the best time to plant bare root peonies (since they are dormant in the fall), container-grown peonies can be planted almost any time.If you are looking longingly at your neighbor’s peonies and wishing you had some right now, go forit!

Many nurseries offer early, midseason, and late blooming varieties, making it possible for you to stretch out the peony season over many weeks. There are 6 flower types to choose from: anemone, single, Japanese, semi-double, double, and bomb. The colors range from pristine white to pink, peach, yellow, magenta, deep reds, and even bi-colors.

Fragrances vary as well—some plants such as ‘Festiva Maxima’ and ‘duch*esse de Nemours’ have intoxicating rose-like scents while others are lemony or have no scent at all. If fragrance is important to you, give them the sniff test before youbuy.

5 Tips for Planting PeoniesProperly

  1. In choosing a spot for your new peony to grow, make sure it will get lots of light—6to 8 hours of full sun is best for producing a profusion of flowers but it will still perform well in a location with morning sun and light afternoon shade. Peonies will not bloom inshade.
  2. Peony plants will need well-drained, neutral soil away from competing tree roots. This plant will grow to cover an area about 3 feet in diameter (and stand 3 feet tall) so give it plenty of room and don’t crowd! Once planted it can remain undisturbed for many years as long as it is floweringwell.
  3. Planting depth is critical; if planted too deeply it won’t bloom. When planting a container-grown peony, cover it no deeper than it grew in thepot.
  4. Try not to disturb the rootball or damage the feeder roots. A newly planted peony can take up to 3 years to reach its full flowering potential but once established, this plant likes to be leftalone.
  5. Be patient. Note that peonies do not flower in their first year of plantingand it may take two to three years for the plant to bloom profusely. Oncemature, a plant in sun can produce as many as 50 flowers each year for a lifetime of beautifulblooms.

SupportingPeonies

Peonies need support while growing due to their heavy flowers and brittle stems of the larger flowering varieties. Peony rings were invented for just this purpose or you can use a wire tomato cage. Placing the support around the plants early in spring is ideal so you don’t accidentally pierce thecrown.

Many of the newer hybrids are being developed with stronger stems to eliminate this problem and single, anemone, or semi-double flowering varieties usually don’t needstaking.

5 Tips on Caring forPeonies

  1. Deadhead peonies after they finish flowering. The petals will brown which isn’t attractive. Cut the stem underneath the old bloom, leaving the foliagealone.
  2. Wait until the fall to cut back the foliage to discourage overwintering ofpests.
  3. Mulch new plants with evergreen boughs or salt marsh hay after the groundfreezes.
  4. The only serious problem peonies ever get is “botyrtis,” a fungal disease can be avoided with good air circulation around the plant. Signs of botrytis are blackened buds and stems. Cut off and dispose of any affected areas (in the trash, not in your compost pile). If you plant properly and avoid crowding, you shouldn’t have thisproblem.
  5. Peonies can be susceptible topowdery mildewin late summer but do not worry. The white, powdery mildew fungus may not be pretty but it seems harmless. Better air circulation can avoidmildew.

If you share my passion for peonies, get out there and enjoy them! Pick lots of of bouquets to perfume the house! Like all good things, peony blossoms won’t last forever and you don’t want to miss aminute!
