Greenhouses offer a unique opportunity to control the environment in which plants grow. While many crops thrive in the regulated conditions of a greenhouse, some are particularly well-suited to high humidity environments.

In this blog, we'll explore a selection of greenhouse plants that flourish in such conditions, making the most of the controlled moisture-rich atmosphere.

1. Orchids 

Orchids are renowned for their beauty and diversity, with over 25,000 species. Many orchids are epiphytes, naturally growing in high humidity environments like rainforests.

In a greenhouse with elevated humidity levels, orchids can thrive, producing stunning blooms in various colors and shapes.

Tips for Orchid Care:

  • Maintain humidity levels around 60-80%.
  • Ensure good air circulation.
  • Use well-draining orchid potting mix.

2. Ferns 

Ferns are ancient plants that have adapted to humid environments over millions of years. They thrive in greenhouses with consistent moisture levels and indirect light.

Ferns come in various shapes and sizes, making them an excellent choice for adding lush greenery to your greenhouse.

Tips for Fern Care:

  • Keep soil consistently moist but not waterlogged.
  • Provide indirect light to prevent scorching.
  • Use a well-draining potting mix.

3. Bromeliads 

Bromeliads are tropical plants known for their vibrant foliage and unique growth habits. They excel in high humidity environments, making them a perfect addition to your greenhouse.

Their stunning rosette shapes and colorful bracts can add a touch of the exotic to your plant collection.

Tips for Bromeliad Care:

  • Keep the central cup filled with water.
  • Provide bright, filtered light.
  • Ensure good air circulation.

4. Carnivorous Plants (Sarraceniaceae, Nepenthaceae, Droseraceae, etc.)

Carnivorous plants, like Venus flytraps and pitcher plants, are specially adapted to nutrient-poor soils and high humidity.

They're not only fascinating to observe but also efficient insect catchers, helping to manage pests in your greenhouse.

Tips for Carnivorous Plant Care:

  • Use distilled water or rainwater to prevent mineral buildup.
  • Keep humidity levels high (around 60-80%).
  • Place them in bright, indirect light.

5. Begonias (Begoniaceae)

Begonias are a diverse group of plants known for their attractive foliage and beautiful blooms. Many begonias thrive in high humidity environments, making them a popular choice for greenhouse cultivation.

They come in various colors and forms, allowing for creative and colorful greenhouse displays.

Tips for Begonia Care:

  • Maintain consistent humidity levels.
  • Provide bright, indirect light.
  • Use a well-draining potting mix.

6. Tropical Fruit Trees (e.g., Banana, Mango, Papaya)

For those looking to cultivate fruit in their greenhouse, tropical fruit trees are an excellent choice for high humidity environments.

These trees require warmth and moisture to produce delicious fruit and can thrive in the controlled conditions of a greenhouse.

Tips for Tropical Fruit Tree Care:

  • Maintain high humidity levels (around 60-80%).
  • Provide ample sunlight and warmth.
  • Ensure proper pollination for fruit production.


Greenhouse gardening offers a world of possibilities, especially for those interested in cultivating plants that thrive in high humidity environments. Whether you're drawn to the exotic beauty of orchids, the air-purifying qualities of ferns, or the insect-eating charm of carnivorous plants, a high humidity greenhouse can be a lush and thriving oasis for these moisture-loving species.

Remember to tailor the conditions to the specific needs of each plant and enjoy the benefits of a thriving, humidity-rich greenhouse environment.
