As a follow up on the posts some information gathered from various sources [mostly Peppers of the world] and some guestimation. C. Pubescens: Thrives in only a narrow temperature range. Some plants may not fruit because there is a self-incompatability in the species. For these to set fruit pollen must be transferred from one plant to another. The species also responds well to shading because the foliage has a tendency to burn in full sun. The growing season is long 120 days or more. Because it is adapted to cooler highland climates it grows best under cooler conditions. Optimum is 80 deg F [26 C] during the day and 55 deg F [12 C] at night. To much fertiliser (nitrogen) will cause profuse growth without flowering or fruit set. My own experience is that fruit set only occurred when temperatures had decidedly cooled. It is my belief that night time temperatures have the most influence as some of our days are still currently in the 26..30 deg C region but nights are much cooler, 10..14 C. Fruit has started to set on the plants I have. Cheers Peter -- Peter Moss E-Mail: email@example.com Of all the things I have lost, I miss my mind the most.
