That's what I think too. The brown leaf can't turn green again, plant would look better if you take that off, but glad you left it on for the pic to show what's going on. Looks like it has a toxic buildup of something in the soil, likely fluoride, to which this plant is very sensitive. Over time, some tap water can alter the PH of the soil also. Has it ever been repotted? The next time it's dry, I would flush the soil with a gallon of distilled (not bottled drinking water) or rain water if possible. Pour about 1/4 of the gallon on it, wait 15 minutes, pour another quart. Wait 15 minutes, then very slowly pour the last half gallon, all over the surface of the soil, not just in one spot. Then let it dry well before watering again. It likes very bright shade, but not much if any direct sun outside. In the house, some direct sun that's not during the middle of the day should be fine. Come on by the house plant forum if you have further questions or need instructions on repotting, best done during summer.

Thanks for your help. I'll be sure to get all the Fatoua villosa out that I can before they go to seed and look forward to seeing the passiflora bloom. I did plant one there but I thought it died too so I planted another vine. I thought it was that one. Ya'll are great!

Thanks for the link florauk. Very informative discussion. I just planted a little plantlet (that I pulled out from some shaded area under a tree in the wild) in a pot. It had just a little bit of roots. Hopefully enough for it to get a foothold. After reading in the Honorie Jobert discussion that it might be a bit invasive I am thinking of keeping it pot bound rather than transplanting it in the ground later.

you guys are awful gracious .. to flip back and forth and back and forth.. and back and forth .. like you dont have anything better to do .... see link ... and it is much easier.. for us lazy peeps.. if you want my effort [for whatever it is worth .. lol] .. that you go to the effort of learning how to paste the pix right here in the post ... ken Here is a link that might be useful: link
