Buddleja davidii

Buddleja davidii, also known as ‘Butterfly Bush’, has dark green leaves in paper-like thickness. It has aromatic purple flowers, and will turn yellow or white in some varieties. With soft branches and fragrant flowers, it is a popular garden ornamental plant. 
The whole plant can be used for medicine, having an effect of relieving cough or eliminating pain. Its flowers can be extracted for aromatic oils. 
Butterfly Bush prefers humid climate and warm sunshine, and it has drought tolerance at the same time. This plant has developed root system but couldn’t survive in water-logging environment. Butterfly Bush is easy to germinate and develop, being resistant to salt or alkali stress. It can survive at -20℃ and overcome winter in the open ground. 
Butterfly Bush can be propagated by sowing. You may keep the soil moist and cover a thin layer of soil onto seeds. Seedlings should be properly shaded, and avoid exposure to blazing sun. 
Propagation by cuttings is also widely used for Butterfly Bush. In the middle of June, you can collect half-wooden branches with several new buds. Remain two leaves in the top of a 10 cm branch, and soak the branch in water for about 60 minutes. You may dip it in auxin solution to help the root growth. After that, bury the bottom of the branches into soil, and spray some water in time. 
In late March to early April, you can excavate the gathered branches around the base of plant. Then remove the attached soil and it is ready to transplant. 
You may choose dry, sunny, and well-drained ground for cultivation. Remember avoid being next to the fish pond, as the Butterfly Bush is poisonous to fish. You can apply some basal fertilizer when transplanting, and no topdressing will be needed in future. Irrigation in summer will help the blooming of flower. 
After the flower withered, it is appropriate to cut residual flower with its branch, in order to promote new branches to grow. Before winter, cut a short part of the plant can help the growth in spring. 
Butterfly Bush has flourishing leaves and large inflorescence, having a long flowering period. It can be planted in roadside, wall corner or lawn edge, and is a rare summer flowering plant.
