Propagation/ Seed Propagation
Seeds were sown into cone-tainers filled with Sunshine # 1 (a soil-less, peat-based media) amended with micro-nutrients (Micromax) and a slow-release fertilizer (Osmocote 14-14-14). Flats of conetainers were placed in greenhouse set at moderate temperatures (70 degree days/50 degree nights.) Seeds germinated readily with no treatment. Most seeds germinated within one to two weeks. (Leptosiphon grandiflorus also needed no treatment before germination).
