Most of the rest of the Peony seeds, somewhat overdue...

All these photos were taken at the end of August... I almost got them posted last week but the Blogger site got hung up. And then more good weather descended and miles and miles passed under the tires of my road bike... Anyways, here they are at last. One species has yet to open its carpels: Paeonia lactiflora, the Chinese Peony, which is predominant in the ancestry of most of our, dare I say common?, "garden peonies".


Carpels of Paeonia mlokosewitschii, the Golden Peony, had taken on an interesting and showy red tone. (These have since opened, but not until about a week ago. Photo to follow)


Paeonia obovata, the third-last of my species to show its seed display.





Paeonia macrophylla, close kin of Paeonia steveniana (some might say identical or close enough to it) but a tiny bit later to ripen seed.



Paeonia officinalis (in this case, subspecies villosa). Not so exotic and showy, but on close inspection the inside surface of the carpels are satiny reddish in tint. None of the officinalis mob here have had the bright red aborted beads; rather theirs are tiny, shrivelled, and brown. Only the viable seed has any size to it.

An interesting development during an Argentine football (soccer) match I was watching on tv today: one of the Ball Boys got red-carded and ejected from the field (well, the margins of it anyways!). The kids had been taking their time in giving the ball to the visiting team when they had won a throw-in.

A few more peony seed shows

These will all look rather similar, as the species here are all closely related within the "Paeonia mascula complex (or grouping)". Photos are all from 31 August, and the pods had mostly been open for 2 days to a week at that time.

(For more information about the species presented, you will find it in the June/July archives.)

Several hundred kilometers later...

Okay, I'm back from a temporary leave of weblog-absence (or leave of my senses, maybe) during 2 weeks of fine weather during which Peony seeds were ripening while I spent my time shuffling the winter's finally-dry firewood into the basement and beating up all sorts of paved local roads on my bike, in search of "a few good hills".

In the Annapolis Valley the fragrance of Queen Anne's Lace has given way to those of various livestock manures. Clears the sinuses anyways.
__________________________

A week ago, and 3 weeks later than the high-altitude form, the "normal" Paeonia steveniana carpels opened. This is one of them. No different, just not in such a rush to mature.

Another interesting set of Peony seeds

This is Paeonia tomentosa, which was the very earliest to bloom. So far only one set of carpels has opened. This set had three, the lower two opened four days before the upper one, which is just opening in the photo.

What is curious about this one is that fertile seeds are a fleshy semi-opaque purpley red (almost jellybean-ish) when the carpel first opens-- as in the uppermost one-- look closely and you can see that some of the seeds are fully oval and large while others (the aborted ones) are flatter and smaller, as in the lower 2 carpels. After a few days the jellybeans darken to black and take on a harder look. But there are still some segments of red on some of those seeds. This is the first species in which I've seen the fertile seeds change colour so dramatically after the carpels open.

And again more Peony seeds

Two fairly similar-looking carpel and seed clusters. The red "berries" are seeds which aborted, or stopped developing partway through their growth; the black ones are the viable seed. Unfortuantely my camera doesn't do a good job with the red ones; they are really a bright red rather than the pinkish tone seen here.

A few more Peony seed carpels

Yes, I'm still here off and on between bike rides... One of the pleasures of the countryside at this time of year is the marvelous scent of massed flowers of the biennial Queen Anne's Lace (Wild Carrot) where it has populated ditches or abondoned fields.

Carpels and the shiny jet-black seed of Paeonia anomala var intermedia. The seed is weakly attached and can be knocked to the ground by a heavy rain; this is not the case with most species.


Carpels and seed of Paeonia veitchii. The seeds are distinctly blueish when fresh but will often change to black when dried for a few months.

Ripe seedpods already?- Paeonia steveniana

Somewhat earlier than expected, the carpels of a Paeonia steveniana plant opened today. The plant is specifically of the "high altitude form" which in flower and in foliage seemed identical with the rest of my plants, to me. But the seed seems to have ripened faster than on the rest of them, which may be a factor of the shorter growing season higher up.

The shiny black beads are viable seed, whereas the red ones are seeds which aborted development before becoming mature. They are actually more red than the photos show; very bright and showy, moreso on a gloomy day than in bright sunlight (due to competing glint off the shiny leafs).

I believe today was the first time in about 2 months when the Environment Canada data for Halifax didn't show any overnight hours with relative humidity at less than 100%!! Fortunately that fog doesn't make it up my "mountain".

And Yet Again More Peony Seedpods- Carpels

For an introductory discussion of these things, see my weblog entry of July 21. This is the last set until the "fall show".

Today, peonies of the Caucasus.

Carpels of Paeonia mlokosewitschii (the Golden Peony).





Carpels of Paeonia tomentosa.






Distinctive carpels of Paeonia steveniana. Much like those of obovata (of 2 days ago) but fatter and green rather than blue-green.




An observation: P steveniana is also called P wittmaniana subsp macrophylla and less commonly P wittmaniana subsp nudicarpa (appropriate to the obviously nude carpels!); and P tomentosa is also called P wittmaniana subsp tomentosa or just P wittmaniana. It's not obvious from the carpels that the two deserve to be part of the same species, but of course there is more to botanical classification than that (please don't ask me what though).

Still More Peony Seedpods- Carpels

For an introductory discussion of these things, see my weblog entry of July 21.

Carpels of Peonia officinalis subsp villosa.








Open carpels of Paeonia mollis. I was rather suprised to see that the seeds of this species are apparently ripe, since the carpels have opened. However the seed doesn't quite have the look of fully developed seed so it is possible that they are all aborted seed, causing the carpels to open earlier than would usually be the case.

Peony seedpods- carpels

The seedpods of Peonies are called carpels. They are generally large and obvious, and can add some summer interest to the foliage groups of peony clumps. Some become quite outstanding in the fall when the seed ripens and the carpels open. Of course, not all the flowers will develop a seed pod, as there is sometimes a failure to pollinate for reasons of weather etc. And not all flowers of a species will have the same number of carpels, so where you see two they may actually have from 1 to 4 or sometimes 5.

The next few postings will show photos of carpels of most of my species. I've separated them by the general characteristics of the plants. Some of them are very similar, some are quite distinctive. Photos were all taken on the same day.
