Rolandvue:1st Week of July: Chickory(white), Golden Rain-tree, Smartweed,Cow Parsnip

If you are waiting for the bus on Charles Street near GBMC, turn and look at the patch of chickory behind the safety railings.  There is the usual tall blue flower but toward the back there are some bright white flowers.  V says this is not uncommon but usually just one white flower to a group.  The photo doesn't show the real difference, will return with better light. Another example of variation in nature.  You can dry the root, grind it into coffee while waiting for the bus. Even close-up does not show the difference the eye sees, maybe a blue white, would need a wavelength analysis.

Further along Charles, almost to the top of the hill near Bellona is the Golden Rain Tree.  Last fall this was somewhat a mystery, just going by the papery fruit, but the flowers make it more certain to be a Rain Tree. This is from Asia, said to be common around temples.  Bladdernut was in the differential diagnosis but the fruit of the golden rain-tree fits as well. This is also seen in Naples Florida, a wide range of hardiness zones, 2 to 7a.

Another common feature along the roadside last week and this week is the grass which I am tentatively calling Pennsylvania Smartweed, or smart grass. Tentative because it doesn't have the joints or knees as prominent as some of the reference pictures.  But it is one of the characteristics of the season.

At least some of the smart weeds have a peppery taste which may be conclusive, it can be used as a seasoning in small amounts.
(update) Checked with a couple of foragers, does seem to be Polygonum pensylvanicum, with small knees or joints.  It is in the buckwheat family.  None of the local samples seemed peppery or smarting to the taste.  Not sure of the variation, when others use it for pepper substitute.

Cow Parsnip is so far an out of bounds topic, but interesting.  The similar but larger Giant Hogweed and the parsnip have a toxic sap from the hollow stem which can cause a severe rash.  The rash requires exposure to the sap,followed by exposure to the sun or ultraviolet rays. This is not in the neighborhood so,if interested can follow the discussion on the web.  The picture is from Cuba Road as it crosses the Western Run bridge, about ten miles north of Rolandvue.  V has found this in the city and forages the early shoots as a delicacy but there seems to be some evidence for the skin toxicity of the older plant.
