A plant pundit comments on plants, the foibles and fun of academic life, and other things of interest.
 Pluot?  Wasn't that formerly a planet?  Actually it's plum-like fruit that is a back-cross hybrid between a plum-apricot hybrid and a plum, all part of the genus Prunus.  In general they are most like a plum, but with the flavor intensified by the apricot parent.  They are actually better than either parent.  Pluots are a good summer fruit, and here's a good idea.  If you are BBQing some chicken, grill a few pluot halves for a few minutes on each side.  Their flavor when hot is just great, tart-sweet intense plumness.

Yesterday was some planned maintenance work at our prairie research site.  The weather was just right for field work: hot and humid, sweltering, a word based on the root "swell".  It was a pretty simple job: find our research plots marked on their SW corner with white pvc pipe standing about 30" tall and stick in it a 5-6' bamboo stake with bright pink flagging on the upper end so we can find the plots later in the year.  In the late spring the poles seem quite absurd in their conspicuousness, but later in the season that changes even when the plot is covered with black 50% shade cloth.  See the difference from May to August?  In this case the treatment, removal of a hemiparasitic plant plus added fertilizer is having an effect (very positive on grasses).  Actually the late season plot isn't marked with a tall pole because this isn't one of the plots that's hard to find. Usually they are marked in early June, and by now it would be a problem with the vegetation at 5-6 feet tall.  But this year because of the draught only a few species were standing above 4 feet tall (compass plant, big blue stem, tall coreopsis).  Most of the prairie species looked fine, just shorter, and the flowering was mostly on schedule.  Unfortunately for the researchers, it isn't so much how tall the prairie is, but how dense the vegetation is, and it was dense, so it was hard to find our pvc pipes anyways, especially the one that was lying on the ground.  You see these research plots are not on some nice neat grid, but scattered around, and even after you sort of become familiar with the pattern, they can be hard to locate in the tall, dense vegetation.

+B+Buchanan+US+FWS.jpg) As mentioned in a recent blog, by definition our summer begins, at least in terms of hot weather, when the cicadas begin to sing.  So far the singing is not the deafening roar it sometimes becomes, but cicada season is definitely upon us in total conjunction with the hot, dry weather.  Of course, shortly after the cicadas appear, so do the cicada-killers, the largest of the digger wasps.  In spite of the fact that they can act rather aggressively, the females who prey upon cicadas seldom sting humans and the males are sting less.  Cicada killers love dry, sandy soil because those are the conditions best for digging their nests.  So what is bad for the plants is good for the cicada-killers, and boy, are we harboring a population of these very specialized predators!  Unfortunately a choice area for cicada-killer nests is near our new pergola, so as you approach you get buzzed, aggressively confronted, by a 3-4 cm long wasp, which, in spite of our great size advantage, is pretty intimidating, and no matter how often you think humans seldom get stung, you tend to react with those well refined primate behaviors to avoid yellow and black buzzy things.  Avoidance, in general is a good behavior, so let's not sell it short just because our knowledge of natural history tells us there is no reason to run unless you are a cicada.  However, Mrs. Phactor is no one to mess with if your are a black & yellow buzzy beast, so if they know what's good for them, avoidance would be a good behavior because if her enjoyment of this new pergola is reduced by buzzy behavior of nesting cicada-killers, they would be well to look elsewhere for a nesting site.  But another possibility exists.  Are these some type of super, double-secret miniature drone designed to instigate panic in human behavior?  Were those little antennas?  And right here in middle America; what gall!  Remember, you heard this first here, but quiet, we don't want homeland security to be trampling the gardens.  The image is from Bill Bucanhan of the US Fish and Wildlife Service; the Phactor was not going to get close enough to photograph one.

While easily bored, the Phactor also can easily amuse himself as long as there is some nature to play with.  And you just never know what new thing you will see ifyou look carefully enough.  So while the various cousins amused themselves with the aquatic equivalent of motorcycles, the Phactor poked around in a nearby salt marsh just to see what you could see.  The seaside ox-eye (Borrichia frutescens) is a pretty common plant in such places in our part of the world.  If you know anything at all about plants it would not surprise you to find that the leaves were thick, succulent, and waxy, common features of plants in dry or salty environments that present similar problems for plants. But did you look closer?  The lower side of the leaf when held up to the light shows this attractive veiny pattern. The lighter green pattern is produced by clear areas, windows to the leaf's interior. Such windows are pretty common in other succulents, but came as an unexpected surprise here. The plant tends to hold its leaves more or less upright, thus presenting this windowed lower surface to the outside presumably so the morning or afternoon rays of sunlight can enter through the windows illuminating the green palisade layer from the bottom side. Most of the leaf mesophyll is almost devoid of chloroplasts.  This is an educated guess; anyone know for sure?
