After sowing, it should be covered with mulching film to keep the germination at 2 5 ℃ Warm, it will germinate in 20 ～ 30 days. The real seedlings can bloom in the same year, but they are not suitable for raising seedlings such as 'Golden Leaf Green Vein', 'Colorful', etc., but only for general seedlings such as canna and purple-leaf canna.
