One of Jay Chou's songs, Rosemary, has a slightly upturned mouth and no hope in her heart.

Flower language: fragrance is a symbol of love and loyalty, and it also represents memories and thoughts.

Rosemary is a shrub and dicotyledonous plant of Rosmarinus in Labiatae. It was introduced to China during the Cao and Wei Dynasties and was occasionally used in gardens. Rosemary flowers and leaves can extract excellent antioxidants and rosemary essential oil, which can be widely used in daily chemical industries such as medicine, food, perfume, air freshener, ant repellent, sterilization and insecticidal.

Maintenance method:

1, temperature: rosemary is cold-resistant, so it should be well ventilated when it is hot in summer, and the ambient temperature should be reduced, and it should not be lower than-10℃ in winter, so it should be moved to indoor culture or temperature protection in time.
