Jaboticaba


Myrciaria cauliflora fruits, or Jaboticaba.
 Myrciaria cauliflora (alternatively Plinia cauliflora; family Myrtaceae) is a small tropical tree with edible fruits, native to Brazil. Its species name is derived from the term "cauliflory," which describes trees which produce their flowers and fruits along their trunk and large branches, as opposed to at the ends of younger shoots. Cauliflory is mostly seen in tropical trees, although what function it might serve seems to be debatable. Possibly, flowers along trunks are more visible to pollinators (or fruits more accessible to animal dispersers) than they would be in the dense leafy canopy of the rainforest. There are no native cauliflorous trees in my area, but a little further south one shrub, the Redbud (Cercis canadensis), shows this condition to some extent.

 Jaboticaba (sometimes spelled Jabuticaba) fruits are pretty tasty, with sweet, grape-flavored white pulp inside of rubbery, nearly black skins. The skins are a little bit tough, but also edible, with a slightly acrid flavor reminiscent of walnuts. In the greenhouse the flowers of Myrciaria self-pollinate, and set an abundant fruit in spring without any special attention.

Spring at Last!


The last of the snow is finally gone, after a consistently cold and fairly stormy period from January into April. The ice sheet remnant in the photo was caught, about to disappear, on May 11. The snow was pretty much gone everywhere else a month ago, to be sure; this spot is on the north side of a parking garage on the UConn campus where a huge pile of snow gets dumped from cleared lots. Ice always lingers there for longer than it does elsewhere, but it's pretty unusual for it to last into May.


The cherry blossoms were out the other week, and this week the apples are in full bloom. The weather has actually been very warm recently (20 F above average temperatures on a few days), so the growing season is catching up rapidly. I'd say that the plants are only a week or so behind schedule at this point, versus a month late back in the maple sugaring season.


The bees are really taking off at this point, although they were delayed for so long that I don't think colony sizes will be large enough to really take advantage of the earlier phases of the spring nectar flow. The weather has also been unusually dry lately, which won't help nectar production, and could lead to a pretty poor year for honey in Connecticut.


The other day in Glastonbury, Ct, I ran across some nice patches of Polygala paucifolia (Fringed Polygala), on somewhat open slopes in pine/oak woods. This plant seems to be fairly rare in this area and I don't know of many localities where it occurs. The color of the flowers is unlike anything else that blooms on the forest floor, and the plants stand out from quite a distance.

32nd Connecticut Cactus and Succulent Show


 The Connecticut Cactus and Succulent Society's annual show and sale is always a fun time, and is impressive as specialist plant shows go, especially considering that it is held by a club in a small state in a part of the country that is very challenging, climatically speaking, for growers of desert plants. And I don't just say this as the president of the CCSS: if you come to Naugatuck Valley Community College for the cactus show this weekend, I can pretty much guarantee that you will see some little gems of the succulent plant world that have never been exhibited at either the elite flower and garden shows of the east coast that have been running since Victorian times, or the dedicated C&S shows run by huge western clubs. I'm sometimes not exactly sure myself how it all comes together, but by tomorrow morning there is going to be another fantastic display of exotic horticulture, incongruously placed in the drab grey of central Connecticut in early April.

Mud Season '15

Crocus cultivars blooming in a warm spot; most spring bulbs are still under the snow pack.
 The weather is slowly warming up, though spring flowers are probably still a good three weeks to a month behind schedule. The bees have been out and about on quite a few sunny afternoons lately, but they're not finding much of anything to eat beyond the Domino nectar flow, as it were. The overall colony survival rate still looks like about 70%. 

A short pause in the sap flow, with the snow pack freshened up, March 28.
  Around the middle of March, the maple sugaring season really got going in earnest, again about a month late. Over the past two weeks, there has been a pretty reliable daily sap flow, and half a dozen  banner sap days when I've collected a gallon from each tap in the morning before work, then come home to find another gallon with some loss to overflow in the evening. Some of the best production has been during rainy thaws, where chilly but above freezing temps have kept the flow going 24 hours a day for several days straight.


This past week, two taps yielded a bit more than 10 gallons of sap (it's hard to tell exactly how much, since I've been skimming ice off of the sap buckets each morning). This boiled down to a quart of maple syrup, in the typical 40:1 ratio. The syrup is looking cloudy in the photo because of "sugar sand," a mineral precipitate that I will allow to settle and filter out. 


Eden the cat is very particular about not walking on snow, but with recent thaws she has been enjoying a much larger field of operations in the fenced backyard. She had been getting cabin fever, with only a couple of inches of open ground under the eaves where she could run back and forth when it was warm enough to venture outside.

March: Lion to Lamb Transition Underway

2015 hasn't had an overly productive maple sugaring season, but it could get better.
 After a warm December, the winter of 2014-15 turned nasty here in Connecticut. Temperatures during the daylight hours are finally getting consistently above freezing and the Sugar Maples are producing a little sap. The flow has been pretty weak so far, and it's a few weeks late, but it's nice to see after a long period of heavy snow and bitter cold.

 The bees are also venturing outside of their hives on especially warm afternoons, for the first time in probably two months. The survival rate was not as poor as it could have been, with perhaps about 70% of the colonies looking good. I am uncertain about the fate of some hives in isolated out yards, because they're too snowed in to reach, for now. Spring is only a little over a week away, and the long term forecast is for more or less seasonable temperatures, at least.
