Impatiens repens

Tuckahoe, NY 10707
This is a tropical plant from Sri Lanka which demands humidity and heat for best performance. Hates really cold weather and will not survive even light frost. It may be extinct in its native habitat.
Not a reliable bloomer for me, nonetheless when it does flower it is spectacular, the bright yellow flowers are larger than the leaves and show up well on this small creeping plant. Easy (and rampant) in terrariums, also possible in pots set outside for summer. Easy to prop from cuttings, I have never seen a seed pod on it.

One of my favorite plants of all time. I found it by accident, growing in a very shady spot under a pine tree. That pine tree got cut down, and the spot where I found it got more, thankfully. I have since, by carefully transplanting seedlings, given it a home along the northern side of my house.
It absolutely cannot take sun. Needs shade, and moist soil at all times.
A hummingbird favorite. If you have this massed in the fall, as I do, you are guaranteed to see ruby-throated hummingbirds here along the East Coast. I read in a bird book that hummingbirds actually time their fall migration according to the availability of the blooms of this plant.
