2 types of Sansevieria plant (mother-in-law's tongue/jinn's tongue/snake tongue) in my home

I have 2 types of Sansevieria plant at home.

Where common or famous names of the plant include mother-in-law's tongue, devil's tongue, jinn's tongue, bow string hemp, snake plant and snake tongue [1].

The look of Sansevieria trifasciata 'Laurentii' that I planted directly on soil.

This one have yellow stripe in its outer layer of the leaves.

This one does looks like Sansevieria zeylanica from 25 species listed in wikipedia [1].

For this one, it have very thin green stripe in the outer layer of the leaf.

Air purification usage

According to a NASA Clean Air Study, along with other plants such as golden pothos (Epipremnum aureum) and corn plant (Dracaena fragrans), Sansevieria trifasciata is capable of purifying air by removing some toxins such as formaldehyde, xylene, and toluene. Sansevieria use the crassulacean acid metabolism process, which absorbs carbon dioxide at night, although oxygen is released during daylight. Nighttime absorption of CO₂ purportedly makes them especially suitable bedroom plants. However, since the leaves are potentially poisonous if ingested, Sansevieria is not usually recommended for children's bedrooms [1].

Feng shui

According to feng shui, because the leaves of Sansevieria grow upwards, the plants can be used for feng shui purposes. Some believe that having Sansevieria near children helps reduce coarseness, although care must be taken to ensure the child cannot reach the plant's poisonous leaves. Others recommend placing pots near the toilet tank to counter the drain-down vibrations. Such placement appears in the 1986 film Blue Velvet [1].

I was hoping to be able to grow more of them and start to replace the aloe vera that I have put in my bedroom with it in weekly basis. I will need to start purify my bedroom and the whole house with such natural and organic plant.

This plant also suitable to put in office or work desk. Especially for those who works in night shift😉.

Till then, have fun in using natural organic plants as air purifier for your home😉.
