Colchicum capense subsp. ciliolatum native to South Africa have high ornamental values as a new pot plant. The species produced seeds by both self-crossings and out-crossings, indicating that the species is self-compatible. Stable seed production was achieved by hand pollination. Optimum temperature for seed germination was 15°C (ca. 80%). The germination was suppressed completely at temperatures higher than 20°C. Seeds were dormant immediately after harvest and the dormancy broke after three months dry storage, irrespective of the storage temperature conditions. GA₃ did not affect seed germination at 25°C. Fluridone treatment restores seed germination at 25°C, but the germination remained less vigorous than germination at 15°C. Seeds incubated at 25°C for 1-2 weeks before transfer to 15°C showed poor germination. However, seeds treated with fluridone germinated well irrespective of the 25°C incubation term. Results suggest that abscisic acid causes thermoinhibition in this species. Application of fluridone and GA₃ slightly enhanced seed germination, but when endogenous gibberellin biosynthesis was suppressed with uniconazole treatment, the seeds did not germinate even though fluridone was administered at 25°C. Seedlings from seeds and one-year-old corms produced a new corm as a dropper. Three years are necessary to produce flowering-sized corms of this species. Present results showed a possibility to horticultural use of this species.
