• The peony season in the Southern hemisphere is now in full swing. Both in South America, Australia and in New Zealand. Some of those are exported to the USA, Europe and Japan of course.

    Here are a few images from a peony seedling field currently in full bloom from Paul and Esther Simmons, who grow and hybridize paeonies (yes, written that way in…[Read more]

    November 6 today, some peonies haven’t been mowed down for Winter. This seedling, garden name Kato001, seems able to compete with the itohs for remaining green foliage. Parentage is Pink Vanguard x Lavender Baby. Might it be a Paeonia coriacea characteristic?

IribovSBW, a Dutch company, has succeeded in mass propagating them without the usual losses or risks that tended to go with the process up until now. In due time the article will appear online on their website, http://www.greenity.nl/magazine/archief , but unfortunately for…[Read more]

    Some images I’ve just received from Dick Houtenbos (thank you!), who grows peonies in Morocco where this species grows in open places in the forest. As far as I know, Paeonia coriacea is the only species growing wild in Morocco, thus there can be little doubt that this would be the species (and it fits with other images I’ve seen of this species).…[Read more]

    I’ve bought this one as Paeonia coriacea, but I’m not sure it is, as I have some others that should be this species and the foliage is different again. The foliage is somewhat tomentose on the underside and the 2 carpels are also tomentose, thus it’s not the most common form of P. coriacea at the very least. From the species key by Hong De-Yuan I…[Read more]

    Yes, it does look encouraging, next year I’ll be able to judge it better, some of the larger divisions should have grown into good looking plants by then. It was a ‘lucky shot’ and it won’t count as an early white though, as it’s purely lactiflora. It might be a rather early flowering lactiflora, but it doesn’t flower with the early hybrids.

    Just received in the mail today, the latest American Peony Society (APS) Bulletin (people from the USA will have received it some time ago). In it: a long article written by Nate Bremer, owner of Solaris Farms, about the shrubby Paeonia x suffruticosa group. There’s also a huge load of new peony registrations (44!) with long detailed descriptions…[Read more]

    Last of the rebloomers, we’ll be digging the first peonies to replant today.

  • Hello Bob,

    Yes, that would be correct. The forum section ‘magazine’ is ‘locked’ for new topics. This is because it is essentially simply an overview of comments on the longer ‘articles’ that appear on the frontpage or in the magazine menu section. I thought it would be nice to have all comments together so it would be easier to get an overview…[Read more]

  • Most of us have peonies blooming in May and June. Some people that live in warmer climates will already have flowers in April and those in (very) cold climates will have them in July. Of course you could also grow

  • An interesting topic and most people that grow peonies will have experienced some frost damage at one time or another.  I’ve been looking for some more information about it and especially on what cultivars might fare best.

  • Well, I have a strange plant, bought as caucasica seed a long time ago. A weak plant, divided and lost most of them, but all white. First seed pod is open, but take a look at the unfertilized ones, that ain’t no red 😳

    Just home from a holiday in Italy, reblooming peonies ready to harvest back home. Will write an article about the results, but not today 😉

    The reblooming experiment with Canary Brilliants seems to succeed. On the left the last remaining flower of the plants not cut down, next to the newly sprouting ones.

    • I’m sorry to hear about the pest problems you had ! Botrytis can be a difficult thing to deal with. Is it in the old stems, is it lurking in the soil ? Has it made it’s way down to the crowns ? Aside from good hygiene, I suspect that a person has to spray. And spray preventively, before any symptoms show up. Not something anyone looks forward to.

      The issue with bad bud covers is an interesting one. And I’ve heard that for some registered varieties, it becomes more of an issue the older the plants become. It may have to do with early season temperatures, but it may have to do with other factors as well. We selected a number of seedlings several years ago, from plants in seedling blocks that appeared to be mature. We dug them and planted them again from the resulting divisions, and two years later when it was time to do further selection, we were wondering why in the world we had ever kept them, because of the poor bud covers they had. This seemed to have to do with the plants being older, because they had looked fine when we first selected them. One would think it would be more of an issue with flowers that are double, but less-double flowers can have short bud covers too.

      Established varieties like Old Faithful can have poor looking bud covers as well, but somehow they develop just fine, so I’m not sure that poorly covered buds is always the kiss of death, but it’s something one would rather not see, that’s for sure.

      • Old Faithful is somewhat the exception to the rule here. It seems the petals can take water standing in the bud/open flower for a very, very long time before becoming infected with botrytis. I’ve never had any problems with flowers from them, notwithstanding the fact that the bud has a ‘rose-bud’ which is exposed to rain, cold and wind for a very long time. So it’s indeed not necessarily that kiss of death. But other varieties are not that resistant. I’ve given up on Moonrise as a cutflower because of these open buds, I got too many complaints from florists that the flowers opened with rotten stamens. I could leave the stems with open buds on the plants of course, not all stems do have an ugly bud, but the proportion of open buds in this cultivar has always been very high the years that I have been growing it. Too bad, as it does have many qualities, floriferous, early, large flower, large buds, yellow color, very sturdy stems. Although there’s also a second reason for not growing it anymore: it smells awkward, and I mean really, really awkward (less of a problem when growing it outside, but as a cutflower…).

        You have noticed in some of your seedlings that they didn’t show those open buds when young, but at a more mature stage, they somehow appeared. Here the problem occurs one year more than the other. I’m not sure it has to do with the plants being more mature, the one location where Vanilla Schnapps showed the open buds, happened to be newly replanted divisions, whilst the locations with no ‘damage’ were older plants (2 years old and 3 years old). Therefore I would think temperature is more an issue. And also the fact that the sidebuds on these same young plants had perfectly closed buds, would make me think it’s the cold that somehow causes this. These sidebuds have developed somewhat later and they may thus have been in another less sensitive stage when the cold (wind?) damaged the further developed main buds. I’ll add an image of another variety Great Northern, which grew here for the first time, it also had an open main bud, but you can also see the sidebud perfectly formed. This is thus also a young plant with both a good and bad bud on the same stem. The open bud turned out to be a flower with several rotten petals and stamens in it, we’ll see if it is a returning issue. I don’t know what other factors could be causing this? Humidity? Soil? Soil probably not I’d think or the problem would be present each year and probably on every flower.

        I’ve not noticed any difference between single, semi-double, or double cultivars. Some cultivars seem more susceptible than others. I should probably take notes what cultivars have most issues with it. And maybe ‘rose-buds’ are another issue, separate from ‘open buds’, the latter primarily being the fact that the outer petals are shorter than they ought to be.

    A small experiment to find out if it’s viable to get flowers in Summer itself. We’ll post the results in a few months time.
