We have found it early successional after removing non-native invasives near
water such as porcelain berry. But this is only temporaty. it quickly
declines to normal as other natives come back in a year or two.

Subject: [APWG] Jewelweed
Has anyone had any experience with jewelweed (Impatiens) native to the
eastern U. S. becoming weedy in valley marsh habitats in the intermountain
West?
I see that jewelweed Impatiens capensis (orange jewelweed) is listed as a
King County (WA) "Weed of Concern".
This species is shown as having a yellow flowered form, which is what we are
seeing.
