Field Notes

Description:

An invasive vine that has really taken off in this park by the water. This image shows several plants, most notably the orange flowers, which are not my subject here - that is Spotted Jewelweed / Touch-me-not / Impatiens biflora. My subject here is the vining plant with stacks of blue berries and triangular leaves. Too mixed up to get just one of the plants as my focus!<br>

<br>The plant is in the stage of mostly green berries, with some turning blue and pink and purple.<br>

<br>This plant was formerly known as Polygonum perfoliatum.

Habitat:

Belle Haven Park next to the Potomac River

Notes:

The orange flowers are Jewelweed.

Also "Tear Thumb", and from the spines I've noticed on it, that's an appropriate name!
Christiane
It is also called Devil's Tail.. A very invasive plant in the tropical north of Australia and the South Pacific!

No worries - I didn't notice it when I revisited, either!

Duh, Ashley....it's clear I didn't even read!! Oooopsy! ;)

Oh - ha - I just noticed I did have that noted under "Notes". But clearly it's not so obvious there. ;-)

You are correct on the orange flowers - I guess I should have mentioned their name above, even though they were not my primary subject in this posting. I'll edit that now. :)

The orange flower looks like Jewelweed or Touch-Me-Nots.... is this the same thing??
