2013 Peony Foliage on Steriods! Peony 'Bowl of Cream'

While cutting the spent blooms off my peonies last week, I couldn't help but notice the size of this peony. It is Peony 'Bowl of Cream'. This plant is just huge. The leaves on this peony are almost a foot long (10 inches). Each leaflet is 10 inches, making the compound leaf 20 inches across! Of all the varieties I grow, this one definitely has the largest leaves! Peony 'Bowl of Cream' was hybridized by Khlem in 1963. It is also a American Peony Society Gold Medal Winner from 1981. The size of this peony foliage convinced me to add another category, foliage size, to my Survey page. I'd like to make peonies more easily identifiable in the future. The more information we have about each peony plant, the easier it will be to identify the specific variety in the future.

2013 How to Deadhead an Herbaceous Peony


Peony with Spent Blooms

After your herbaceous peonies have finished blooming, you can deadhead them (remove their spent blooms). There are several purposes of this. Firstly, it keeps the plants looking neat and tidy. The dried brown flower petals and sepals aren't very attractive hanging on the plant. Secondly, it prevents the spread of disease. The petals of peonies are perfect hosts for fungi to grow. If left on the plants, they absorb and hold moisture and warmth very well, making a perfect home for a fungus. Thirdly, it allows the peony to divert its energy towards creating a larger root instead of developing seed pods and seeds (unless you want to grow a peony from seed). With a larger root, the peony can develop into a larger plant the next growing season.

Brown Peony Petals and Sepals

When pruning the peony plant to remove the dead blossoms, the plant should only be cut back to just above the next leaf node. Take your pruners and follow the stem from the top near the bloom or bloom cluster down to just above the next leaf nodule. This is the point where the peony should be cut back. Use pruners that have been disinfected to make a clean cut at this point. You can use rubbing alcohol or vinegar to disinfect your clippers between cuts. I usually keep a small, lidded, plastic container filled with one of these biodegradable disinfectants to dip my clippers in while pruning.

Prune Peony Right Above the Next Leaf Nodule

Since peonies do not continuously produce new foliage growth, as much of the foliage should be preserved as possible. The leaves of the peony plant are needed to generate energy for storage in the peony's underground tuber. The plant will use this stored energy to regenerate itself the next year. Sometimes I will prune the plant back a little further than the next leaf nodule if I find a stem that has been severely affected by disease. This is identifiable by black spots on the stems or leaves, wilting, and/or leaves or stems that have turned totally black. If you find a stem like this prune that stem back to the next healthy leaf nodule. If the entire stem has been affected and turned black, remove the entire stem, and be sure to bag it for garbage collection.


That's it. If your peony was newly planted last fall, you should water it during any summer dry spells to help it survive its first year. Now your peonies are ready to collect as much energy as possible until the weather gets cool and the foliage goes dormant! At which point you'll need to learn How to Cut Back an Herbaceous Peony. That's why I love peonies, they are relatively carefree and deer do not eat them! :-)

2013 Monrovia Itoh Peony 'Keiko'™ 愛幕 (Adored)


Monrovia Peony 'Keiko'™ 愛幕 (Adored)

So I saw these Monrovia Itoh peonies at a local garden center near me. They looked so lovely, they looked so intersectional, they looked so... expensive! As you can see from the tag on this one, they are tagged to sell for $89.99. However I definitely didn't pay that much. The garden center had them on sale for 30% off, and I also had a $50 Visa gift card that someone had given me. So I ended up paying a little more than $17 with tax after the sale and gift card.

Monrovia Peony 'Keiko'™ (Adored) Tag

These Monrovia peonies that they were selling are part of Monrovia's Japanese collection of peonies with Japanese names to honor the creator of Itoh peonies, Toichi Itoh, of Japan. The intersectional peony I selected was the largest plant I saw and the one with the best looking foliage. It is named Peony 'Keiko'™ (Adored), and from the picture of the bloom, it looks like it will be a lovely pink color. With it's Japanese name I figured this peony would feel much at home in my Japanese garden near my pagoda statue and Japanese irises. So that's where I planted it. I can't wait to see it bloom next year! Also I will have to keep my eye on these at the garden center to see when they go on clearance. :-)

2013 American Peony Society Gold Medal Winner - 'The Mackinac Grand'

At this year's 2013 American Peony Society Board Meeting, the APS Board elected Peony 'The Mackinac Grand' as its 2013 American Peony Society Gold Medal Winner. I do not currently grow this peony, nor do I have it on order. So I will have to get a specimen for myself to evaluate here in my growing zone. Since I was a member of the seated board, I was able to vote for the Gold Medal winner, but I decided to abstain since I felt I did not have enough knowledge of the candidates to elect the finest specimen. However from its photos, it appears to be a pretty plant with flowers held nicely above the foliage. Peony 'The Mackinac Grand' was hybridized by Reath and registered in 1992. The petals appear to be a true red with a bright yellow center of stamens showing through a large round of fluffy red petals. I'm interested to try this newest Gold Medal Winner!

2013 Deadheading Removing Spent Peony Blooms

I just spent the last 2 days deadheading my peonies - removing the spent blooms on my peony plants. You can do this on all of your peonies if you like. Or if you want to see if any seeds will develop in the seed pods you can just deadhead those with no seed pods - like most double and bomb type peonies. These types rarely set seed. The single and semi-double peony forms are more likely to set seed. I've heard it is very important to remove all of the peony foliage and never compost it. So any peony foliage I remove from my gardens is always sent to the landfill. If you have seen the effects of botrytis on peonies, then you know why this is so important. Botrytis is a fungus that can be spread in wet conditions most easily on developing and growing foliage. It will cause a black spotting on the leaves and stems, bud abortion, and in heavy cases black fungal growths with spores. So as you can see my peony refuse is bagged and stored in my trash receptacle until my friendly neighborhood trash man comes to take it away!
