Citronella Plant: Growing And Caring For Mosquito Plants

The Citrus Family (Limes)

Citronella plants are native to tropical areas of Asia, Africa and South America. They have been cultivated since ancient times for their fragrant flowers. These flowers are used in perfumes, cosmetics and other products. The leaves and stems of these plants are often eaten as food or made into incense sticks.

The leaves and stems are also used as insect repellents.

The Citron Tree

The citrus family includes many different species of trees with very different characteristics. Some are evergreen; others deciduous; still others produce fruit only once a year, while some produce fruits all year round. All citrus trees bear edible fruit, but they differ greatly in size and shape depending upon their preferred season of growth.

All citrus trees are members of the genus Citrus. There are over 500 species of citrus trees worldwide, and each one produces its own distinctive flavor and aroma when ripe. Most varieties of oranges, lemons, limes, grapefruits and tangelos come from the same tree family as citronella plants. Each variety grows differently from the next in terms of color, size and shape.

However most varieties will produce white or yellow fruit if grown properly under proper conditions.

Citronella Plant

Citronella plants are an evergreen shrub with long, narrow leaves. They grow to a height of about one meter and produce white flowers with yellow interiors. These flowers are then followed by small, green berries that turn yellow when ripe. These berries contain tiny, black seeds that are slightly oily in texture.

Since citronella plants grow all over the world, they have many different names in different places. They are also known as the lemon scented geranium, mosquito plant, mosquito repeller, apelemwe pwani and palmarosa.

Citronella Plant: Growing And Caring For Mosquito Plants on

Soap plants grow as multistemmed trees up to 15 meters in height and can be identified by their flaky bark and dark green foliage.

The soap nut, as it is also known, produces a nut that is encased in a grey, paper-like shell. These nuts grow directly on the tree, and can be found either singularly or in pairs, usually between the branch and trunk.

Once the nuts are harvested, they are dried and then the shell is removed to reveal a white nut that has a soapy texture.

Common Names: Albizia, lebbek, soapbark tree

Family: Bignoniaceae

Extract from ‘Complete Survival Guide’

By Ambesh Satapatha

The easiest way of collecting honey from a beehive is to smoke the bees into a calm state, before removing the honeycomb. Bees are most calm after they have consumed honey, so smoking them will not only make them less inclined to attack, but also cause them to expend their energy in creating more honey instead of attacking you.
