It can grow normally above 8 ℃ and can endure low temperature of - 14 ℃. The cold resistance is very strong. In severe cold areas, if there is a thick snow cover, the bulbs can overwinter in the open field, but they are afraid of the heat.

(1) Early promotion: tulip bulbs were harvested in the middle and late June, and then placed at 34 ℃ for one week. Then it was transferred to 17-20 ℃ for 50-55 days to promote flower bud differentiation and organ formation. Finally, the plants can be planted from late September to early October after cold storage at 7-9 ℃ for 6 weeks, and blossom in December.
