Place of originAfrica and Asia

Characteristics of the roselle plant 

The plant and the fruit are known by the same name (roselle) even if only one part of the plant contains the flower. Likewise, the scientific name is the same for both the plant and the fruit (Hibiscus sabdariffa). It belongs to the Malvaceae genus.

Stem of roselle 

This plant has several stems that can reach 2.5 meters in height. These stems are abundant, multi-branched, smooth, and with irregular-edged leaves. Its stems are either light or dark red which tends to blend with purple, except for the varieties that produce fiber. These varieties have green or yellowish stems.

Roselle leaves 

Lower leaves are undivided, unlike the ones at the top of the plant, which are separated by 3 to 5 lobes.

Flower 

Its flowers tend to be solitary and grow below the leaves, specifically in their axils; they have a fleshy texture, red wine color and reach 4 to 5 cm long; they have 5 petals with a conical shape similar to a poppy and several long thorns that are found around both the flower and the stem.

Description of the roselle fruit 

The flowers of this plant are often taken as fruit, even so, the crop has a fruit that is described as a series of capsules with 5 divisions that in some may be 6.

When the plant matures, its divisions or compartments are filled with 15 to 20 seeds that look like dark brown kidneys. These seeds have small hairs that cause itching and burning of the skin when touched; they are covered by a red, shiny, fleshy layer that is 2 to 3 cm long, and this is the element of the plant that is marketed.

5 properties of roselle that you need to take advantage of 

It fights hypertension 

This plant can control and prevent mild and moderate hypertension as it encourages the relaxation of veins and arteries. It is thought that this property is caused by the anthocyanins present in this flower.

Even, some scientific research seems to show that frequent consumption of this species would have an impact similar to that of some antihypertensive drugs such as captopril. Nevertheless, it is not necessary to replace the drugs prescribed by the doctor in these cases, because more scientific evidence supporting this theory is still needed.

It protects your heart 

The roselle not only takes care of your heart by regulating blood pressure but also helps to reduce triglycerides and bad cholesterol and instead increases good cholesterol. This can happen because, thanks to this flower, the liver can omit the absorption of fatty acids. It also promotes fat burning in the body and reduces the assimilation of triglycerides in the intestine.

It reduces blood sugar 

This property is because roselle can decrease the action of certain enzymes of the pancreas and intestine that digest carbohydrates in the small intestine, thus avoiding glycemic peaks and an exaggerated production of insulin.

It helps to lose weight 

Due to its amount of polyphenols, especially anthocyanins, flavonoids and phenols such as chlorogenic acid, quercetin, galloyl, and caffeic acid, the frequent intake of roselle helps to lose weight and avoid obesity.

This may be due to the fact that the aforementioned elements help reduce sugar in the body, cause fewer carbohydrates to be absorbed in the intestine, and stimulate fat metabolism. It is also likely to control appetite because certain studies show that this plant can influence certain hormones, such as leptin and ghrelin that regulate your desire to eat.

It protects your liver 

This flower can decrease the appearance of fatty acids that occurs in the liver. Because of this, it can treat and prevent fatty liver because it improves its performance. On the other hand, roselle can increase the number of enzymes that detoxify the body, and thus liver damage would be reduced.

History and origin of roselle 

There are 4 theories regarding the origin of the roselle. The first one is held by most people, they tend to think of places like Africa in its tropical and subtropical zones as the site of origin of this plant because of its numerous appearances in Egypt, Sudan, and Senegal.

On the other hand, there are those who believe that this plant comes from Asia.

A small group of botanists indicates that this crop comes from the West Indies.

The renowned botanist H. Pittier states that the Jamaican flower has its origin in the tropical regions of both Asia and Africa (this idea would partly support the first theory) but that from there it was introduced and nationalized in the American continent.

How is roselle cultivated?   

There are a number of requirements to be taken into account when growing this plant. Below, we’ll show you what they are:   

Soil   

This plant requires deep, moist, loamy, sandy, acidic soils rich in organic matter to become more productive and for its roots to expand freely. The soil should have a pH level between 4.0 and 7.5, the ideal range is 6.5.

It must not be planted in flood-prone soils because excess water could cause parasites to appear and this plant is very weak to the attacks of these pests. For this reason, it is better to choose soils that do not sink or that are slightly undulating.

Climate 

Being a tropical and subtropical plant, this flower is very weak to cold and is unlikely to survive frost: it needs warm and dry climates with temperatures between 25°C and 30°C for its good development. This plant also requires a high amount of sunlight, about 11 to 12 hours a day during growth.

Roselle planting method 

Some materials needed for planting this plant are:

  • Cardboard containers
  • Jamaican flower seeds
  • Organic fertilizer
  • Soil
  • Pots
  • Water
  • 10 grams of vermiculite (substance with minerals)

Once you have these materials, you can proceed as follows:

  1. Mix the vermiculite and compost, and put this mixture in cardboard containers.
  2. Put the seeds in the containers with the mixture. Be careful with the spacing between crops. These containers will be useful when transplanting crops. It is necessary to sow the seeds in a sunny place.
  3. They should be watered abundantly to moisten the plant and to close the porosities of the soil so that it is compact.

If you live in warm climates, water the plant daily, but if not, it will be enough to water it 3 times a week.

  • Do not forget to water this plant regularly. Usually, after 5 days the first shoots begin to emerge.
  • When the plant reaches a height of about 50 cm (probably 35 days after planting), it is time to prune it so that its branches expand sideways and thus have more space to reproduce and greater uniformity in its production and development.
  • It is of great importance to make this crop weed-free, especially in the first 25 days. Weeding can be done manually or mechanically.

If you want to accelerate a little the process of plant growth and do not want to start from scratch, you can cut a branch to the plant perpendicularly. Then put the stem in a container with water and wait for the first roots to grow, which are those needed to plant a crop.

It takes 6 to 7 months for roselle to bloom.

Harvesting roselle 

Once all its flowers have appeared, wait for the flower structure to mature within about 20 to 25 days. By that time, it should have a strong red color surrounding the fruit and should be fleshy. To harvest the plant, it must be plucked in the shade.

At harvest, the flower structure is separated from the fruit manually or mechanically and the fruit is left to dry in the shade for 6 to 10 days before the seed can be harvested.

Post-harvesting roselle 

It is planted on a temporary basis, but the product obtained lasts throughout the year if stored in aerated and shaded places, preferably sealed to prevent the presence of pests.

For the leaves and flowers, it is recommended to store them from 18 months to 2 years at the most to preserve their physical, chemical, and therapeutic properties. These products cannot be stored in humid places because these places favor the presence of mildew.
