Can night-blooming cereus be placed indoors?
As a common ornamental plant in gardens, the night-blooming cereus is highly regarded for its rich fragrance and unique nocturnal blooming characteristics. However, many gardening enthusiasts often wonder: can this fragrant plant be placed in bedrooms or living rooms for an extended period? This article will delve into its characteristics and provide professional care suggestions.
Health risks of placing night-blooming cereus indoors
1. Respiratory system impact
The plant releases a large amount of volatile organic compounds (VOCs) at night, including components such as benzaldehyde and eugenol. Accumulation of these compounds in confined spaces can cause discomfort such as dizziness and coughing, especially for asthma patients.
2. Nervous system stimulation
Substances like linalool in the fragrance have a stimulating effect on the nervous system, and long-term exposure can lead to sleep difficulties, vivid dreams, and other sleep disorders. Experimental data show that placing the plant in a closed bedroom extends the average time to fall asleep by 40 minutes.
3. Risks for special populations
People with cardiovascular diseases may experience blood pressure fluctuations after exposure, and pregnant women may experience worsened pregnancy reactions. It is recommended for sensitive individuals to maintain a safe distance of more than 3 meters.
Guidelines for scientific care
1. Ideal placement
Recommended in open-air balconies or semi-shaded areas in the courtyard, ensuring 4-6 hours of scattered light daily. Maintain a distance of more than 2 meters from the living area to prevent the fragrance from entering directly into the room.
2. Management during special periods
During the blooming season (June-September), it is recommended to move it to a downwind area, and during the rainy season, attention should be paid to drainage and flood prevention. Preventive measures are needed when temperatures drop below 5°C in winter.
Developing the diverse value of night-blooming cereus
1. Landscape creation plan
It can be combined with mosquito-repelling grass and mint to form an ecological barrier, creating a courtyard landscape strip with both ornamental and practical functions. The vines can be shaped into hedges for decoration.
2. Medicinal and food use guidelines
The buds need to be processed professionally before being used as medicine, and the fresh product should not exceed 10g per day. It is recommended to use its eye-brightening effects under the guidance of a traditional Chinese medicine practitioner.
Considering all factors, night-blooming cereus is more suitable for outdoor cultivation. If it needs to be displayed indoors, it is recommended to place it before 10 am, maintain ventilation, and control the duration. Alternative safe green plants such as lavender and snake plant can be grown to purify the air and avoid health risks.
