Effects of sowing time and pinching node positions on the growth and flowering of snapdragons (Antirrhinum majus L.) in the warm temperature zone in Japan were investigated. Snapdragon cultivars, ‘Maryland Pink’, ‘Light Pink Butterfly II’ and ‘Potomac Early White’ were sown on July 16, July 31 and August 14, pinched just above the second or third nodes, and grown under greenhouse conditions where the night temperature was kept above 11C in the winter. When ‘Maryland Pink’ was sown on July 31 or August 14 and pinched at the third nodes, the number of cut flowers and the length of primary lateral shoots from the third nodes increased. Regardless of sowing time, pinching at the second nodes was suitable for ‘Light Pink Butterfly II’ with the increased length of primary lateral shoots from the second nodes. For ‘Potomac Early White’, sowing on July 16 with pinching at the second or third nodes and sowing on July 31 with pinching at the third node were suitable and increased the number of cut flowers in the winter season.
