| Abstract:
Today's market is looking for new potted plants. Dwarf bearded iris are naturally short and have showy flowers, so seem to have potential as a new flowering potted plant. The objective was to determine the correct photoperiod and chilling to produce flowering out of season. Some cultivars flowered without chilling but best flowering was achieved with 4 to 8 weeks at 3–4°C. Most cultivars flowered slowly or not at all under short days unless they have been chilled. Plants grown under supplementary HID lighting flowered earlier and were better quality than plants grown under natural photoperiod. | |
