Answer: I am not aware of any difference in starting Purple Ruffles as opposed to other basils, although some gardeners do report that basil in general is prone to damping off. There are some disease problems that can affect basil and so you might want to try another batch of seed and see if that helps. In addition, although I have not found this noted, it is possible that the particular variety is more sensitive to cold or excess humidity and damps off more easily. When growing the seedlings, take care not to water the foliage, ensure good air circulation, keep the temperature at about 70 degrees, and plant thin and thin them early and as needed so they are not crowded. I hope this helps you trouble shoot.
