Wind bell tree varieties: the difference between golden wind bell tree and magenta wind bell tree, there are several breeding methods.

The genus Tabebuia is a tropical tree species, which grows well in the central and southern flatlands after it was introduced to Taiwan. Horticultural landscape cultivation is increasing in recent years. It is wet and cold in winter in the north, so it is necessary to guard against cold damage. There are two main varieties: Golden blueberry and magenta blueberry.

There are two kinds of common cultivation in Taiwan:

One is the golden wind bell tree (T. chrysantha), alias the yellow flower wind bell tree, the Brazilian wind bell tree, the golden wind bell tree, the yellow bell wood, the Yibei tree, is the Brazilian national flower, is a kind of tree that will change the style and appearance with the change of the four seasons. Spring is in full bloom from March to April. It blossoms first and then grows new leaves. When it is in full bloom, there are many leaves and few leaves. The flowers and colors are bright and bright and colorful. It often makes people stop and admire this beautiful encounter. But the flowering period is shorter than the former, withering and falling in about ten days. Green buds and tender leaves begin to sprout in summer, with long striped capsules with dense hairy surfaces gradually growing, and then the fruit is ripe and cracked, and the seeds with thin wings at both ends are scattered and spread all over the ground with the wind; autumn is still full of branches and leaves; after the beginning of winter, the leaves gradually fall, and the branches are bare, showing the beauty of vicissitudes; in recent years, many roads in south-central Taiwan have been widely planted as street trees.

The other is T. Pentaphylla, alias pink blueberry, Paraguayan blueberry, rose blueberry and safflower Yibei. Before the new buds germinate in spring, the racemose or conical flowers blossom first, the Corolla peach to magenta, and when in full bloom, the florets form clusters and the trees are full of flowers, showing a charming and tender landscape. Before the flowers wither, palmately compound leaves begin to grow, forming a sense of beauty that peach to magenta flowers match with emerald green leaves, adding romantic amorous feelings to spring.

Propagation can be done by sowing, cutting or high-pressure methods, mainly by sowing.

The suitable time for sowing is from spring to summer, and the optimum temperature for seed germination is 24-28 degrees Celsius, that is, the germination rate is higher; if sowing and raising seedlings in autumn, the seedlings should be kept warm and overwintered during low temperature or cold current in winter; the seedlings can be transplanted with a height of about 15 cm, which is best before sprouting in spring, and transplanting is taboo in winter.

The cutting takes spring and autumn as the suitable period, cut 1-2-year-old strong branches, each section is about 10-15 cm, keep it moist after cutting, and root and grow seedlings after about 3-4 weeks.

Spring is the appropriate time for high pressure, and it is best to do it during the rainy season, and it is appropriate to choose the strong branches from last year. The selectivity of cultivated soil is not strict, but the loam or sandy loam rich in organic matter is the best, the cultivation site should be high and dry, and the drainage should be good. The sunshine needs to be sufficient, like the direct light of the whole sunshine, 70-100% sunshine is better, and the birth and flowering is bad in the shade. When planting seedlings, burying holes should be large, and organic fertilizers such as compost and rotten chicken manure should be buried as base fertilizer, which will grow rapidly and strongly in the future; during the period of young trees, appropriate amount of topdressing can be applied to accelerate their growth and height; adult trees are in the peak growth period from spring to summer, with sufficient water supply, a small amount of topdressing once a month, all kinds of organic fertilizers or three elements are ideal, and increasing the proportion of phosphorus and potassium fertilizer is beneficial to flowering. Pruning is most avoided in adult trees from late autumn to early spring, so as not to cut off the differentiated flower buds and affect flowering. Pruning once after flowering, so that lateral branches can be divided and more flowers can be bloomed. Is a tropical tree species, suitable for cultivation in high temperature, frost-free hot and humid areas, the temperature below 16 degrees Celsius growth pause, no matter how low the temperature begins to fall leaves. Winter needs to be warm, sheltered and overwintered, and it is better to grow in the middle and south of Taiwan, while in the north, it is cold, rainy and humid in winter, so it is necessary to strictly guard against cold damage. Strong nature, like high temperature and humidity, heat-resistant, drought-resistant, not resistant to frost and cold, rapid growth, less diseases and insect pests, suitable temperature 23-32 degrees Celsius.
