It looks like Columnea to me too. Be glad you have all those green leaves! That's a sign of new growth and means your plant was happy to be repotted! They will turn darker in time if they have good light. They like bright light, but not direct sun. I have mine near a south-facing window but it's off to the side so that only the VERY early morning sun may be on it for just a short time.

Please help! Our manettia luteorubra has a problem: The leaves turn brownish-black (see picture). It is flowering and growing, and the very new growth is at first not affected. We planted it last spring, and we noticed the browning leaves some months ago. We have a second firecracker vine that does not show the symptoms and looks very healthy. It is next to the sick one, maybe four feet away in the same patch of soil. Can anyone tell us what's wrong? We would be happy about any hint! Thank you! Image link:

First of all, how do you post pictures here? Second, the link 'effects of glyphosate on tomato' left above by jean001a has a picture of a glyphosphate effected tomato plant and it looks just like mine do. To: dickiefickle, all my garden plants are planted in a garden, in the ground, except for a cucumber and a pepper. One problem I had, which is why I'm having such a bad weed problem, is that when I first decided to plant this garden, my plan was to use the rear-tine tiller owned by my landlord to till all the soil in the garden area, then to till in some bulk combo soil. However, the tiller has both a seized transmission and engine, so its useless. This meant that I had to plant the garden in what was currently a lawn area, with grass and weeds. So I planted the plants just like I would plant a shrub or perennial. I dug holes about 14"-16" in diameter, about 14" deep, then I mixed my soil up and filed these holes, then planted the plants in the holes. Before planting, I didnt spray Roundup on the garden area, because I figured my landlord would want it to be a lawn again in the future, after the garden was picked. But later, she agreed to allow me to spray it, but by that time the garden was 3 weeks old. However, the grass and weeds are still growing, so I first just weed-wacked them, but as the veggies grew larger, I couldnt take the chance of weed wacking the veggies by accident. But there are too many to pull every few days, so i did what I would normally do in an ornamental bed. I first pulled the weeds under the drip line of the veggie plants, then I carefully sprayed Roundup to the other weeds, with the wand very low to the ground, on a non-windy day. Also to dickiefickle: As far as my soil being too moist, the holes I'm growing in are 14-16" deep, and we live on the East coast where we have a drought just about every summer, where it wont rain for weeks at a time. Most watering is done by hand, and I never water too much or too often. Usually every 3 days or so, unless it rains, so the soil is never too wet for very long. However, I planted a Dahlia, a 40" variety called 'Contraste' back on about May 5. It already had a long stem growing out of the tuber, so once I planted it, it immediately was 3" above ground and started growing leaves at once. Then on about May 20, we had an extremely rare 7 day long rain spell, where it rained on and off every day, and was constantly overcast. It actually rained about 3-5 hours per day. One day after the rain ended, the sun came out and some plants were wilting a little initially due to the bright sun for the first time in 8 days, but then most plants perked back up, except for the one Dahlia. It continued to wilt for 8 more days, til I dug down to the tuber, and discovered that it had rotted from the bottom up and was slimy and easily crushed in my hands. ****Anyway, my most important question at this point is: Now that I've pruned the tomatoes back below the yellowing areas on top of main stem and laterals, will those tomatoes grow new stems from the area where pruned like most plants do(2 or more new stems), or will no new growth start where pruned, and only new lateral will grow from between the main stem and leaf branches? How do tomatoes normally react to their stems being pruned?

Like the two earlier post, that's natural for this plant at this time of year. Especially for one grown in full sun. I have noticed that my vine maple growing under the canopy of large conifers, the leaves are all still green, while out in the open they are showing some red.
