I bought this mystery hanging basket houseplant at Lowes. No label. It has these small purple/brown semi-trumpet shaped flowers 2-4 to a cluster, growing from the stem right at the junctures where leaves also grow out. These are really small -- less than an inch long. The plant is profuse, but seems fussy - it had a very short but very cold ride home in the bed of my truck, and I gave it just enough water after hanging it to run through the bottom. It's in a north facing window in a pretty warm spot, over my turtle aquarium, so it will get diffuse but not intense light all day. I do have dogs, and the turtle, and I some hairy purple flowers are poison, as are some trumpet shaped ones... what is it?!
