The following characteristics on flowering of Lavandula×interm edia were shown clearly based on the present research. 1. The plant is a typical long-day and green plant vernalization type plant. 2. The early 13-hydroxylation pathway of gibberellin metabolome through biologically active GA_1 exists in the plant. 3. Gibberellin is essential for flower bud formation of the plant, however, it can not replace a trigger by low-temperature. 4. Biologically active endogenous GA_1 concentration increases in advance of flower bud formation of the plant. 5. GA_3 treatment can promote flower bud formation in case of an insufficient amount of low-temperature. As mentioned above, flower induction of the plant might be possible by GA_3 treatment according to the amount of low-temperature demand of the plant.

Lavandula×Interm Edia的以下特征是基于d绿色植物的植物。2。在植物的花芽形成的情况下，可以根据植物的低温需求量来促进花芽形成。
