[APWG] Jewelweed

[Marc Imlay]

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.

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.
