Roselle, also known as the King of Hearts, Roselle, and Blood Fruit, is an “Internet celebrity” plant in recent years. It is native to the tropics and subtropics and likes warm climates. It is planted more in Guangzhou, Hainan, Fujian, Guangxi and other regions. For outdoor planting, the northern climate conditions are not suitable.

1. Get to know the "Internet celebrity plant" Roselle

Roselle is an annual herbaceous plant of the Malvaceae family, which is the same family as the crop cotton. Roselle plants are 1-2 meters tall and have pink flowers. After the flowers die, the fruits grow in the calyx. The main edible part of the Roselle flower is its calyx.

Roselle (calyx) is rich in anthocyanins, vitamins and other nutrients. Because it has more organic acids, it tastes sour. It can be dried to make tea, used to extract pigments, or made into jam, preserves, wine making and other uses.

2. The growth environment of Roselle

Roselle is a tropical or subtropical plant. The optimal growth temperature is 24-32°C. If the temperature is lower than 10°C, the plant will stop growing. Above 5°C, it begins to wither. In addition, during the growth period of Roselle, there are also requirements for night temperature, preferably higher than -20℃.

It is generally planted in warm low-altitude areas. The natural climate conditions in the north are not suitable for planting Roselle.

3. Planting of Roselle

Roselle is propagated by seeds. It is usually planted in April and blooms around October. But the flowers bloom for a shorter period of time, half a day. The entire flowering period lasts about 3 weeks, and the picking of roselle flowers starts basically in November.

Roselle is generally grown in Hainan, Fujian, Guangzhou, Guangxi and other places. According to some reports on the Internet, Guangzhou and other places have a lot of cultivation, and it was once highly speculated. However, with the development, the sales are not very smooth.

I have also seen reports on greenhouse planting. In Dinghai, Zhoushan, Zhejiang, in early November, the rose flowers in the greenhouse were in full bloom, and viewers came in droves to develop both the ornamental value and the edible value.

For planting Roselle, you need to choose a soil type with good drainage, and acidic soil is more suitable.

The above is the knowledge about growing Roselle. I hope it will be helpful to everyone.
