James, Sounds like you have a solitary C. pubescens plant, right? This exerpt from Dewitt and Bosland's "The Pepper Garden" may identify the problem: Regarding cultivation of C. pubescens: "Some plants may not fruit because of a self-incompatibility in the species. To set fruit, pollen must be transferred by bees or humans from a neighboring plant." The book also states that C. pubescens does not cross with any of the major cultivated species. So it sounds like your plant is lonely and needs a mate! Hope that helps, Russ James Robertson wrote: > A tale of great woe... > > My C.
