The development prospects for Butterfly Bush are extremely broad

Butterfly Bush is the most popular landscaping tree species in Europe and America, and is highly suitable for promotion in North China, Central China, East China, and parts of Northeast and Northwest China. In terms of landscaping effects, this tree species has many advantages. It is a perennial, fast-growing, semi-evergreen shrub with grayish-green leaves that are large and opposite, about 25 cm long. From summer to late autumn, it continuously blooms with lush panicles, the inflorescences about 40 cm long, in diverse colors including purple, blue, pink, white, and yellow. The flowering period lasts up to 6 months, which can compensate for the scarcity of blooming plants in summer. The flowers have a strong fragrance, attracting many butterflies that dance around. Even in the winter of December, the leaves remain green. Its branches are arching and slender, covered with small flowers of various colors, forming colorful flower bands that are very beautiful and spectacular. In landscaping, Butterfly Bush can be used for planting on lawns, and can also be used for greening and beautifying slopes and wall corners. It is very beautiful for decorating rock gardens, courtyards, roads, and flower beds, and can also be used as cut flowers. Butterfly Bush is cold-resistant, drought-resistant, tolerant of poor soil, tolerant of partial shade, tolerant of extensive management, and intolerant of waterlogging. The plant has extremely strong sprouting ability and is extremely tolerant of pruning, requiring no highly specialized skills. The cost of using Butterfly Bush for landscaping is relatively low. Taking the planting of Butterfly Bush in a landscaping project as an example, if used for flower bed greening, with a plant and row spacing of 50 cm, 2,000 plants can be planted in 500 sq m. If small seedlings raised in winter and spring are planted in the project in April, and the price is 2 yuan per plant, 500 sq m would only cost 4,000 yuan; if 60 cm tall seedlings from the previous year are used, at 3 yuan to 4 yuan per plant, 500 sq m would only cost 6,000 yuan to 8,000 yuan; if the plant and row spacing is increased to 80 cm to 90 cm, the unit cost would be even lower. Whether using small seedlings of the current year or large seedlings from the previous year, once planted in spring, by July to August the same beautiful scenery can be enjoyed. Compared with conventional landscaping tree species, the cost is basically the same, while the landscaping effect of Butterfly Bush is far superior to that of conventional tree species.
