Grass sparrow flower, also known as white flower oil sesame vine, flower Shan sesame vine, sparrow flower. It is a national second-class protected plant, which is cultivated in southern China. When the flowers are in bloom, they are hung in a string, such as sparrow flowers flying, which is of great ornamental value. So a few years after planting, the sparrow blossoms? When will it blossom?

The specific flowering time of the sparrow flower

Most of the finches grow in a warm and humid climate, which is shady and drought-tolerant but not cold-resistant. Born strong and fast, with a strong climbing ability, the flowering period is generally from early March to mid-April every year, and it will be delayed by about half a month in case of cold weather or Rain Water's numerous months.

When the flower blossoms, its petals will be rolled up into wings, and the whole flower is exquisitely carved. Because of its "head, eyes, mouth, wings and tail", it looks like a small Finch gathered together, which makes tourists linger and take pictures one after another. The sparrow flowers are light green or milky white at first, lemon yellow when they are in full bloom, and then pink and orange. There are usually 10-20 flowers on each string, and many can grow to 20-30. There are usually hundreds of thousands of sparrow flowers on a tree, which is very spectacular.

How to reproduce the sparrow flower

Choose the method of cutting to propagate the sparrow flower, first of all, the branches selected as cuttings must be strong enough, and we also need to prepare a solution with rooting hormones such as rooting powder, and soak the lower end of the selected branches in the solution, so as to promote the cuttings to take root quickly. After that, we can insert the branches into the wet sand bed, pay attention to shading, and keep the soil moist at any time, so that roots can take place in about a month. The method of using cutting propagation is generally carried out in spring, so it is easier for cuttings to sprout, so we must pay attention to sunscreen and moisturizing when cutting in summer.

Striping Propagation of Sparrow

What is needed for striping propagation is the vine that falls to the ground. Cut the lower end of the internode of the vine and bury it in the soil. At this time, it is necessary to keep the soil moist. After the vine buried in the soil grows roots, the vine can be cut off from the original plant, and then it can be cultivated. We can apply fertilizer properly to promote the growth of the new plant.

Sowing and Propagation of Sparrow

Sparrow flowers can also be sown and propagated. Finches bear fruit in autumn, and we can get 5-10 seeds from the fruit. When we sow and reproduce, we should choose full seeds with short storage years, which have strong vitality. Before sowing, we have to soak the seeds in water to make the seeds absorb water and swell, usually soaking for 7-10 days. After the seeds expand to a certain extent, put them in a dark, moist place, and wait for the seeds to grow into real leaves. They can be transplanted to the soil and planted, which can grow to about 1 meter a year.
