Here is a tip for you - It comes back from seed every year and germinates kind of late spring to mid summer. Keep watch and learn when it germinates. When you start getting competition that chokes it out, spray the competition with gly a few weeks before it germinates. You will get that explosion of Jewelweed back.
One of best staging areas we have had during dry early season bow hunting was a Jewel Weed patch in woods bordering a corn lot. The Jewel Weed held a lot of moisture and the deer came to it a solid hour and a half before dark.
I have some of this and I wondered what it was. I have never seen it flower and I almost have never saw it with leaves. But that stem is identifiable to me in that third photo. It’s mangled by the deer at my place.
