Recently, a member of the public in Wuhan Garden Expo Park photographed a cluster of blue-purple flowers shaped like small bells, in the many pink and white flowers appear to be extraordinarily delicate and unique. Wuhan Institute of Landscape Architecture, senior engineer Dong Likun recognized the picture after the introduction, which was included in the "IUCN Red List of Threatened Species" of the blue carpets, native to South America, has not yet known Wuhan introduced the blue carpets flowering in the fall.

On Nov. 4, a reporter from Changjiang Daily found the blossoming bluebonnet at the east end of the Creative Park in Wuhan Garden Expo Park. The flowering tree is about 3.5 meters high, the tree diameter is slender, the top stem produced more than 10 branches, of which four branches have more than 10 blue-purple flowers, and other branches have budding flower bones.

"The blue carpets landscape effect is better, but it is more demanding on the growing environment. Wuhan belongs to the subtropical climate, which is not conducive to the growth and flowering of the tree." Wuhan Garden Expo Park greening responsible person Zhang Wenhua introduced, blue carpets like warm and humid, sunny environment, suitable for growing temperature of 22 to 30 ℃, especially intolerant of frost and snow. Wuhan summer average temperature of 33 ℃ or more, the average temperature in winter at 0 ℃ or so, blue carpets growth is inhibited, the probability of flowering is extremely low.

In 2020, the garden to explore new tree species for landscaping, specifically from Australia to introduce 50 blue carpet seeds for pot seeding, five months later, the saplings grew to 40 centimeters high. After winter, the garden moved them into the greenhouse for warmth and frost protection. Last winter, green workers will be many pots of bluebonnet planted outdoors, wrapped in plastic film to keep warm, carefully maintained, I did not expect that one of them actually blossomed in the golden autumn. In the tree plants, blue flowers are not rare, so the bluebonnet flowering is more peculiar.

Dong Likun introduction, the blue carpets by the "IUCN Red List of Threatened Species" as vulnerable species, in addition to the origin of Brazil, China's Guangdong, Hainan, Guangxi, Fujian, Yunnan and other places have been introduced to cultivation, especially in Kunming as a large area of street trees planted. At the turn of spring and summer every year, a large area of bluebonnets blossom like a blue mist, which is very spectacular and beautiful. Wuhan less planted blue carpets, he had not heard of the blue carpets in Wuhan flowers. Generally plants need a certain amount of heat accumulation to bloom, and Wuhan is warmer than the southern city late, spring and summer temperature accumulation is not enough to let the blue carpets blossom, so the blue carpets in Wuhan Park Park will bloom in the fall.

The flowering of this bluebonnet is about 3 meters high, and the flowers bloom at the very top.
