No, that looks very different in flower and stem from TLD. TLD is very compact and has fuzzy branches with a greyish tint, and the blooms have very little white on the edges. Smells like sharp lemon, too.

I have been following this thread and investigating each pepper variety that has popped up here as I am planning a grow out of the best variety. The one I grew a few years back was a C. baccatum that was quite prolific, pendant fruit, nice heat and had the citrus flavor expected: LEMON DROP - hot; Andean Aji Type; 2 to 3 inches long by 0.5 to 0.75 inches wide; medium thick flesh; matures from green to bright yellow; pendant pods; green leaves; 24 to 30 inches tall; Late Season (80-90 days); C.baccatuum. 20 seeds. But I am also looking at a C. chinense variety: LIMON - very hot; 1.5 to 2 inches long by 0.5 to 0.625 inches wide; medium thick flesh; matures from green to yellow; pendant pods; green leaves; 12 to 18 inches tall; Early Season (60-70 days); Uses: Prolific; from Peru; C.chinense. Maybe I'll have to grow both? I realize there are variants, look how many yellow varieties are available at PepperMania, so I'm still looking. NECM

Emerson and Nancy are great. I learned a lot from visits with them. As a pair they are kind of like a sweet and sour candy. You can decide which is which ;)

Looking at the pictures you posted, I see the foliage is receiving direct sunlight, but the soil in the container is not receiving sunlight. Your tree's annual winter leaf drop could easily be caused by a problem called Winter Leaf Drop (WLD). When a tree's foliage is in direct sun, the leaves become over heated and need to transpire moisture to cool.. However, is the root system is to cool the roots cannot supply the needed moisture for transpiration. Therefore, the only option the tree has to cool itself is to discard the leaves. For container citrus trees, if the foliage is receiving direct sun, the container also needs to receive direct sun, or be heated by some artificial means. You should be able to find much information on this forum or the Internet about WLD and citrus. - Silica
