Which types of plants are not suitable for growing indoors?

Greenery is an integral part of many Vietnamese households, bringing freshness and purifying the air. However, not all plants are suitable for indoor cultivation. This article by Thịnh Phát provides a detailed analysis of plants homeowners should carefully consider, helping you choose the most appropriate greenery for your living space.

1. Strongly Fragrant Flowers

While floral scents often create a relaxing and romantic ambiance, some flowers emit overpowering fragrances or contain volatile compounds that can lead to health issues, especially for those sensitive to strong smells.

• Flowers with Intense Scents to Avoid Indoors

Several flowers have potent aromas that homeowners should reconsider before planting indoors, such as jasmine, roses, orchids, and tuberose. These plants can cause breathing difficulties, dizziness, and headaches. Prolonged exposure to their strong scents may lead to fatigue and adversely affect health.

• Health Impacts of Strong Fragrances

Intense floral scents can negatively affect human health by stimulating the nervous system, leading to symptoms like fatigue, headaches, dizziness, and nausea. Sleeping in rooms with strongly scented flowers can severely impact sleep quality, resulting in prolonged tiredness.

Additionally, volatile compounds in flowers can irritate the respiratory tract, causing issues like coughing, shortness of breath, and potentially exacerbating asthma in affected individuals. In severe cases, it may lead to pneumonia, posing significant risks to children and the elderly.

• Allergy Risks from Pollen

Another concern is the risk of pollen allergies. Many individuals may be sensitive to pollen without realizing it. Frequent exposure can cause sneezing, a runny nose, itching, and skin rashes, affecting daily life quality.

Pollen disperses and clings to household surfaces, making complete removal challenging. Even with regular cleaning, sensitive individuals may still be affected by residual pollen in the living space.

• Safe Alternatives

Instead of completely avoiding flowering plants indoors, homeowners can consider safer alternatives. Opt for flowers with mild, pleasant scents that are not overpowering. Flowers like chrysanthemums, sunflowers, or lavender can be good choices, enhancing the beauty of your living space without adverse health effects.

2. Plants with Thorns or Sharp Leaves

• Feng Shui Perspectives on Sharp-Leaved or Thorny Plants

In Feng Shui, the shape and characteristics of objects directly influence the energy flow (or “chi”) within a space. Plants with sharp leaves or thorns are considered “small arrows” continuously emitting negative energy. This can lead to unease, tension, and even conflicts within the family. Moreover, many such plants are believed to dissipate positive energy and wealth in the household.

• Negative Impacts on Living Spaces

Firstly, these plants can pose safety hazards, especially for children and pets. Sharp leaves or thorns can cause cuts or scratches upon accidental contact.

Furthermore, some sharp-leaved or thorny plants may secrete toxic substances. For instance, oleander, despite its beauty, contains harmful toxins. Accidental ingestion or contact with its sap can be dangerous.

• Plants with Sharp Leaves or Thorns to Avoid Indoors

Several plants with sharp leaves or thorns should be reconsidered before indoor cultivation. Cacti, with their sharp spines, are viewed as symbols of aggression in Feng Shui. They can create feelings of unease, hinder positive energy flow, and are believed to bring misfortune, illness, or familial discord.

Dracaena, with its pointed leaves, is also advised against for indoor planting according to Feng Shui beliefs. The sharp shape of its leaves is thought to generate negative energy, affecting harmony and luck within the family.

3. Choosing Feng Shui-Friendly Plants

To avoid negative effects, homeowners should select other types of plants. Plants with round, soft leaves or vibrant flowers are often preferred. They bring positive energy and a relaxing atmosphere to the living space. For example, money trees or ornamental peppers are considered safe choices that bring good fortune to homeowners.

Additionally, pay attention to the placement of plants indoors. If you genuinely wish to grow sharp-leaved or thorny plants due to personal preference, ensure they are positioned in areas that do not obstruct pathways or cause discomfort to family members. Harmony in the living space depends not only on plant selection but also on their arrangement and care.

4. Conclusion

Ultimately, selecting ornamental plants for your home should not solely be based on aesthetics, but also carefully consider their impact on Feng Shui and human health. Caring for and maintaining greenery not only beautifies your living space but also enhances the quality of life for every family. Therefore, always listen to your instincts and adjust environmental factors in your living space to achieve optimal harmony.
