What is lavender?

Another name for lavender is Lavandula. It is a part of Lamiaceae mint family and is a species of flowering plants. It is normally found on Canary Islands and Cape Verde. It is also found in southeast India and Northern and Eastern Africa. Many species of lavender are grown in mild climate. It is generally used as a culinary herb or an ornamental plant for gardens. Lavender is also used in the preparation of essential oils. Lavandula Augustifolia is a popular known species of lavender and it has a specific color.

Description of lavender

Short lived perennial plants are included in the genus lavender. Small shrub and subshrubs are also included in it. The shape of the leaf is quite unique across all the genus. The leaf shapes are quite simple in some common species. The leaf shapes are of diverse color in some other species, like they are pinnate or pinnately toothed (leaflets on side of the stems). The leaves in most of the species are covered with indumentum. Essential oils are present in them. Most of the flowers which are present on the plant leaves are present on the spikes. The spikes are in branched form in most species. Colored bracts are produced on some of the species on the apices. The color of the flowers might vary depending upon the species and ranges from violet to blue. The color can also sometimes be purple or black. The sepals of the flower have long and round shape. Five lobes are present on the corolla and it is also long and round in appearance.

L. pedunculata, L. dentata and L. stoechas were known in the times of the Roman Empire. Later, in the Middle Ages these were divided in two species which are Lavandula (L. spica and L. latifolia) and Stoechas (L. dnetata and L. stoeches). Both of these species were combined by a popular scientist named Linnaeus. He came to know about five popular species in his book named Species Plantarum, which are L. spica, L. pedunculata, L. stoechas, L. multifidia and L. dentata. L. carnosa and L. pinnata were made known in 1790.The later was formed to Anisochilus. 12 species were known in 1826, and 18 species were known in 1848.

Dorothy Chaytor did the modern classification in the district of Kew in 1937. Many mediatories were left in the 28 species which were put forward. Dentatae, Chaetostachys, Spica, Stoeches, And Pterostoechas were the part of the section. The commercial and the cultivated forms were present in the Spica and Stoechas part. Three species were present within Spica named L. Latifolia, L. Lanata, and L. Augustifolia. On other hand, four species were present in Stoeches whose names are L. pendunculata, L. viridis, L. dentata, and Lavandula stoechas. Dorothy Chaytor claims that a mixture of spike lavender and L. augustifolia were present in garden varieties.

Many scientists have researched on lavender in the recent years. Andrews and Upson suggest that three further subgenuses are present in Lavandula. The first variety is subgenus Lavandula. Mostly the shrubs and leaves are a part of this genus. This species is mostly grown as oil and ornamental plants. This species is commonly present in the North and West Africa and in the Mediterranean region. Another subgenus is known as subgenus Sabaudia. These two species are present in the Eritrea and Arabian Peninsula. These are often placed in the genus Sabaudia because they are quite different in comparison to other species. Herbs and shrubs are a part of genus Fabricia. Ornamental plants are present in this species and they are spread throughout India and Atlantic. Many hybrids are also present in horticultural usage.

Study of the word lavender

Some people suggest that the source of the English word ‘Lavender’ is a French word ‘Lavendre’. Some other people think that the Latin word Lavare is the place of origin of this word, which means the mixing of plants. Some people also think that the common name in the European history is the place of origin of this name. This name “Lavandula” was first coined by Linnaeus. Some other people claim that this word is derived from the Latin word Livere which means blue in color. English Lavender is the commonly used name for some species. Spanish Lavender or French lavender is the term used for some other species. English Lavender or Old English Lavender is the term used for L. augustifolia. Spanish lavender is the term used for L. lanata and L. dentate, whereas the term used for L. stoechas is French Lavender.

The English Lavender, popularly known as Lavandula Augustifolia, is cultivated widely. Some species are also prepared artificially. L. dentata, L. multifida and L. stoeches are the most commonly grown species of lavender. These species of plants are grown in the natural environment. They are also grown in gardens all over the world. They are also grown in some places as a garden escapes. No harm is caused by these species most of the times. But these species have proven to be dangerous in some cases. It is considered harmful in Victoria and has been considered as a poisonous plant since the 1920s. A popular species of Lavender named Lavandula stoeches is considered harmful the Australian government is thinking of putting a ban on this species. In Spain, it is considered as a wild plant.

The lavender species bloom and come at their top where there is full sun. The different species of lavender are quite beneficial and don’t need any kind of fertilization. Only good and clean air is required for their proper growth. The growth of the plant in humid areas can be a cause of concern because fungal infections can be caused in the plant, which leads to the deterioration of the plant. One of the reasons for the deterioration of the root is that the mulches in the plant can trap the moisture. It is better to grave materials such as crushed rocks.
