Is it possible for last year's sunflower to germinate after winter?

Sunflower is a succulent plant of portulaceae. Although it is a perennial herb, it can only be cultivated annually because it is not resistant to cold. In some warm southern and coastal areas, perennial seedlings can also be cultivated, and cuttings can be carried out after sprouting in spring. Secondly, sunflower can also be kept for sowing. You can collect some seeds in late summer and early autumn for planting Spring sowing the next year.

Sunflower can support perennial roots, as long as the rhizome is not frostbitten, it can germinate in spring.

The natural flowering period of sunflower is from May to October. After entering the frost solar term, the branches and leaves above the rhizome will gradually turn orange. At this time, the northern region needs to move the flowerpot into the warm indoor balcony or corridor for wintering. In the area where the winter temperature is not lower than zero, it is necessary to keep the soil dry and put it in a warm and ventilated place for maintenance. During this period, it is still necessary to maintain the basic survival water. As long as the rhizome is not frostbitten and the climate is warm to about 15 ℃ in spring, its branches and stems can again emit a little new green. Wait for the branch to grow to a certain length, and then trim some branches for cutting propagation.

Most sunflowers can bear seeds, so they can form the habit of collecting seeds and be ready for emergencies.

Although the sun flower is not resistant to severe cold, it has a large amount of flowers at its full bloom stage. Besides natural pollination, it can also be artificially pollinated, so it is possible to collect seeds. You can use a brush to pollinate in the full bloom period. When the seed pods are fully mature in late summer and early autumn, shake the small seeds on the paper with the help of a newspaper or A4 paper, and then collect them. After the seeds are fully dried, they can be planted in the spring from March to April. Generally, it can sprout in 10-15 days after sowing, transplanting in one month, flowering from May to June, and the whole flowering period can be as long as half a year.

In addition to potted plants, sunflowers can also be planted and grafted. In our Hunan area, it is a common ornamental plant in the courtyard and green belt. Because the temperature in winter is rarely below zero, the seeds dropped in the previous year germinate naturally in spring. It is quite a feeling of "spring breeze blowing and growing again"! Sunflower not afraid of heat, not afraid of barren, facing the sun brilliant bloom, is a positive flower, like its friends can raise up!
