The intersectional Itoh hybrid peonies are a cross between the traditional herbaceous type, and the tree peony. These sturdy and strong growers die back to the ground like perennial forms, but produce sturdier stems and large flowers, often in colors only found in tree peonies such as Yellow. This variety is ‘Bartzella’.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

\n<\/div>\n
I don’t know if you’ve noticed this or not, but this seems that 2015 is the year of the peony – at least, in our gardens in the Northeast. \nThe reasons are unknown, but it could have been our awfully cold (or awesome?) winter, or just might be something to do with better varieties coming into the market and thus, into peoples gardens. I have received so many questions about peonies lately – most seem to be about weak plants, or trying to get their peonies to bloom, and more than a few about when to transplant. I felt that it was worth a quick post (it’s a little long, now that I look at it) on how I grow peonies, and some shared thoughts on these lovely yet sometimes difficult plants.<\/p>\n
Ask gardeners who have peonies in their garden and they most likely will just exclaim that “they are easy”, often adding that they do “little to nothing other than pick them each June”, but to those of you who either struggle with peonies, or who are looking to plant some this year, there are a few tricks to know that may help you.<\/p>\n
First, a brief primer about peonies –<\/p>\n
Most experts divide peonies into about 5 distinct types<\/p>\n
1. Herbaceous – these are your classic peonies. You know, Martha Stewart’s peony garden, long rows of every shade of magenta, coral, pink, peach, salmon and white. The term herbaceous means that they will die completely to the ground come winter, and reemerge again in the spring.<\/p>\n
2. Tree Peonies – These are peonies that form woody stems which do not die to the ground every winter (OK, sometimes they do, but generally speaking, in milder areas, they will form longer and longer woody stems, never as bushy as a shrub, but when they are in full leaf, they will have the stature of a shrub. The large foliage will still drop off in the winter, but with each year, the plants should get larger and more impressive in bloom.<\/p>\n
3. Intersectional or Itoh Hybrids – these are the newest peonies on the block, and they are spectacular. A cross essentially between the above two types ( herbaceous and tree), they carry the best characteristics of both types – stronger stems, larger flowers in a broader range of colors, yet they die to the ground every autumn.<\/p>\n
4. Rock Garden Peonies – These are generally higher elevation or smaller woodland species, great for rock gardens or alpine gardens, or for special places where their fantastic ferny foliage can be appreciated. I only call these out differently from the below ‘species’ category, as there are not some named varieties coming into the trade, and most catalogs categorize them separately as ‘rock garden’ types.<\/p>\n
5. Species peonies – There are species, or wild peonies in all of the above categories except Intersectionals. Over the past couple of decades, a better selection of species have been introduced, most make terrific garden specimens given time, as most species take a painfully long time to mature int he garden. These are plants which our parents and grandparents only wished that they could grow, and once you see one full grown, you will want any one of them in your own garden.<\/p>\n

\nMy personal story with peonies goes way back to my childhood. Living now in the garden where not only I was raised, but my father and his brothers, I am fortunate to have old peonies which my grandmother raised. I never met my grandparents, since they lived here from around 1906 until 1945 or so ( my dad died a year ago last week at 100 – clearly, I was the ‘accident’). Peonies played a role in my budding botanical interests as a child. My mother like to tell the story of how she and Elenore (the woman across the street who still lives here at age 90- Hi Elenore!) dug and transplanted peonies from a neighbors 18th century home (Mrs. Hook), down the road. They planted them near our little concrete goldfish pond in the late 1940’s, where roses once grew. These varieties, combined with my grandmothers became the foundation of the peony collection.<\/p>\n
\n<\/div>\n
Most are lost now, but they were the annual highlight of the garden until I moved back to take over the property in the 1990’s. When I decided to build the greenhouse in 2001, the only way to get a tractor into that side of the yard, was directly over the peony garden, which to be honest, by then was failing somewhat due to shade from trees which only have grown taller over the years. I was able to save a few, but most did not recover.<\/p>\n

<\/td>\n<\/tr>\n

A couple of my mom’s original peony varieties still in bloom this week, after a thundershower. They are weaker than most new selections, and fall over from the weight of their blossoms, even when not wet. But come on – they are like an annual visit from my mom, so they are priceless to me.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
\n<\/div>\n
\n<\/div>\n
\nIt may seem sad to lose these old varieties, but I think that I could replace most of them, with a simple visit to a good peony nursery. I am certain of a few of the varieties, which are most iconic such s ‘Festiva Maxima’ – a classic variety circa 1851, but with a smaller garden, I have to admit that I am enjoying the newer selections as they not only produce a better show when in bloom, they also have foliage which looks terrific for the rest of the summer.<\/span><\/div>\n
I am smitten by the newer Itoh Hybrids, often yellow or in warmer shades – you may have seen them sold at your local nursery in 5 gallon Monrovia pots for anywhere from $60 to $200. Don’t think that these are anything like your old fashioned peonies – they are superior, and although expensive, they are worth the investment, if you think of them as adding a shrub or a hydrangea to your garden.<\/p>\n

\nItoh Hybrid peonies are far superior to many of the older selections of herbaceous, but there are plenty of good herbaceous ones too.<\/div>\n
A few weeks ago I posted this tree peony blooming in front of the greenhouse. It stayed in bloom for nearly 3 weeks.<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
\nWhen to divide peony plants<\/p>\n
Peonies can be divided – in autumn, if you have a large clump which is more than ten years old, or one which suddenly isn’t performing as well as before. Dig the entire clump up with a deep root ball, and carefully wash off as much soil as you can. Be careful, as buds will have formed already near or just below the soil line. The soil may completely fall off the thick roots, as the clump may look more like a clump of brown parsnips than anything else. Try to be generous with your divisions, as smaller portions will take years to recover. Leaving 3 or 4 roots to a trio of bud might be ideal. Carefully set into a prepared hole, no deeper than how they were before, and water well.<\/p>\n
As for the term ‘prepared hole’, it depends on where you live, but Peonies enjoy a slightly acid soil, which might be one reason why they do so well for us here in New England. A pH of 6.0 -7.0 is ideal. Lime is rarely needed, as is heavy fertilizer. Some older books used to quote that same advice as for asparagus – well-rotted manure, deep hole, etc — but come on, who has access to well rotted manure these days?<\/p>\n
A sensible hole prepared as one could prepare for a shrub is all that is needed. I apply a granular balanced fertilizer once a year (a 10-20-20 is strong, but OK if time released or granular – or look for an analysis where the first number, which is nitrogen, is lower than the second two numbers – one wants strong roots and flower bud formation, more than foliar growth.). granular fertilizer should be scratched in around the crowns, being careful to not allow it to touch any growing parts. I sometimes apply an annual application early of a granular super phosphate in March as well. More importantly, in fall when plantings, a kickstarter handful of 10-10-10 for each crown is a good baby-food insurance application of food, which can be helpful when first setting out new plants into your garden. It makes more sense to feed early in the plants life, as mature plants with adult roots do find without any additional food.<\/p>\n
Aside from an annual clean-up of foliage after hard frost, and the removal of seed pods (dead-heading) peonies are carefree, as the foliage remains until late autumn. If you wait until spring to clean up herbaceous plants, be sure to cut the stems back to an inch or so above the ground. It’s best to not leave these to die naturally through the winter, and don’t try to pull them off of the plant in the spring, as they are stringy and can pull out or damage the roots or small buds – I learned the hard way.<\/p>\n
Overall, Peonies are easy – once you get past the first 3-5 years of them ‘settling in’. Remember, there are cemeteries and old gardens where there are peonies growing un-cared for, and they have been blooming for more than 50 years. They are truly long lived, once you get them established. Just remember, plant then in fall ( not those 4 inch boxes of plants one sees in the spring at Home Depot, Lowes and Tesco – order yours from good retailers in late summer for fall delivery). Beyond that 50 year mark, they can even last a lifetime ( or even 2 or 3 lifetimes, as in my garden), which may be the finest reason of all to invest in the best plant that you can.<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"
