Overview of the plant

Bletilla formosana is native to Taiwan and is commonly called the Taiwan Ground Orchid. The plant is known by several other names, including butterfly orchid, Hyacinth orchid, and Chinese Ego Plant.

Description of the plant

The Taiwan Ground Orchid is a terrestrial orchid that grows to an average height of 20-30 cm. The plant usually has six to eight leaves, which are dark green in color and grow up to 30 cm long.

The flowers of this orchid are showstoppers – each flower spike can have up to ten flowers of pastel pink or purple color. The large, flat lip of the flower is white in color, which adds a beautiful contrast to the rest of the flower.


Taiwan Ground Orchids are known for their hardiness and durability. They bloom in early spring, and the blooms last for an extended period, sometimes lasting for up to 6 weeks.

The plant attracts bees and butterflies, which helps in pollination. It also helps to create a habitat for beneficial insects, which can help to keep pests at bay.

Plant cultivation and care

Let us take a look at how to cultivate and care for this beautiful orchid.

Preferred growing conditions

Bletilla formosana prefers well-drained soil with moderate to high moisture levels. Ideally, the pH level of the soil should be between 6.0 and 6.5. The plant requires full to partial sunlight exposure.

The Taiwan Ground Orchid can grow in temperatures ranging from 5-30C, but it will not thrive in places with extreme temperatures.

Potential pest and disease issues

Bletilla formosana is generally resistant to pests and will rarely be affected by diseases. However, you should still be on the lookout for pests such as aphids, spider mites, and scale insects.

These pests can be removed by cleaning the foliage with a gentle soap solution. Be sure to rinse the foliage thoroughly with clean water after the cleaning.

Planting and maintenance tips

Planting the Bletilla formosana is best done in spring or autumn. Ensure that the soil is moist before planting.

When planting, make a hole about 2 inches deep and place the rhizomes in the hole with the buds facing upwards. Cover the rhizomes with soil and compress the soil to get rid of any air pockets.

Watering the Taiwan Ground Orchid is crucial, and the plant should be watered frequently. The soil should neither be too wet nor too dry.

Once the plant has established itself, it can resist drought, but it still requires moderate moisture to bloom beautifully. Fertilizer for the Bletilla formosana should be applied every 3-4 weeks during the growing season.

Use a slow-release fertilizer to provide nutrients to the plant. Be careful not to overfertilize, as this can lead to the plant producing too much foliage and not enough blooms.


The Taiwan Ground Orchid is a beautiful addition to any garden. With its elegant blooms and unique, hardy characteristics, it is easy to cultivate and maintain.

By following the tips outlined in this article, you are guaranteed to have a stunning display of flowers that will have your garden buzzing with life. Whether you are an experienced gardener or an amateur, you will have no trouble growing and caring for this plant!

Plant propagation methods

Propagation of Bletilla formosana can be done in two ways: sexual and asexual reproduction.

Sexual reproduction

Sexual reproduction involves seeds, which can be produced by pollinating the flowers with a brush or other tools. After pollination, the flower will produce a seed pod that ripens into fruit.

The fruit should be harvested when it turns yellow-brown, and the seeds inside should be removed from the fruit.

The seeds should then be cleaned, dried, and allowed to stratify for several weeks.

Stratification involves exposure to cool temperatures, which helps to trigger the germination process. Once the seeds germinate, they can be planted in a seedbed or individual pots, depending on your preference.

Asexual reproduction

Asexual propagation is a faster and easier way to propagate Bletilla formosana. It involves dividing the plant’s rhizomes, which are the underground stem structures responsible for storing nutrients and producing new shoots.

To divide the rhizomes, gently dig up the plant during its dormant period when the foliage has died back. The rhizomes can then be separated into several pieces, each with at least one bud and several roots.

The separated rhizomes can then be planted in individual pots or directly in the garden. Ensure that each rhizome is planted at the right depth, and then water it well.

Within a few weeks, each rhizome will produce new shoots, resulting in new plants.

Plant adaptations to different environments

Bletilla formosana has several adaptations that enable it to survive in different environments. These adaptations include:

Light availability

The Taiwan Ground Orchid prefers to grow in areas with full to partial sunlight. Its leaves are adapted to absorb the maximum amount of sunlight and perform photosynthesis during the day.

However, if the plant is in an area with too much direct sunlight, it will wilt or suffer heat stress.

Moisture availability

Bletilla formosana prefers well-drained soils with moderate to high moisture levels. Its roots are adapted to absorb water efficiently and prevent waterlogging, which can cause root rot.

However, if the soil is too dry or waterlogged, the plant will struggle to get enough moisture, and its growth will be stunted.

Temperature tolerance

Bletilla formosana can grow in temperatures ranging from 5-30C. Its leaves are adapted to regulate the plant’s temperature by losing excess heat through transpiration.

However, if the temperature is too high or too low, the plant will experience stress and may wilt or die.

Pest and disease resistance

Bletilla formosana is resistant to most pests and diseases. Its leaves are adapted to produce a natural toxin that repels some pests.

The plant’s roots are also adapted to excrete chemicals that kill some pathogens that can cause disease.


In conclusion, understanding the propagation methods, as well as the adaptations of Bletilla formosana is crucial to grow this plant successfully. With the knowledge of how to propagate this beautiful plant through sexual or asexual means, you can create as many plants as you want.

Also, understanding the plant’s adaptations to different environmental conditions will help you create an ideal growing environment and ensure the optimal growth of the plant. With proper propagation, care, and maintenance, you will have a breathtaking display of the Taiwan Ground Orchid in your home garden.

However, if the lighting is insufficient, you can use grow lights to supplement the natural light. It is essential to keep the soil evenly moist and avoid overwatering.

The plant should also be fertilized regularly using a slow-release fertilizer. The indoor humidity level should be kept between 40-60%, which can be achieved by using a humidifier or placing the pot over a tray filled with water.

Taiwan Ground Orchids can be grown indoors without any major issues. However, it is essential to monitor the plant’s humidity levels, as they are prone to pest infestations in dry conditions.

Usage of the plant in outdoor settings

Bletilla formosana is a perfect addition to any outdoor garden. The plant is hardy and can grow in various garden environments, including rock gardens, shade gardens, woodland gardens, and mixed borders.

When planting Taiwan Ground Orchids in an outdoor setting, ensure that they are planted in well-draining soil and have access to moderate to high moisture levels. The plant prefers full to partial sunlight exposure, but it can also grow in shaded areas.

The plant does well in temperatures ranging from 5-30C, making it ideal to plant in zones 5-10. The plant can be planted in the ground or grown in containers.

In outdoor settings, Taiwan Ground Orchids are rarely affected by pests and diseases. However, they can be attacked by slugs and snails, which can eat the leaves.

You can use slug and snail baits to control the pests. Maintain a regular watering schedule to keep the soil moist but not waterlogged.

It is also essential to fertilize the plant regularly using a slow-release fertilizer to maintain optimal growth and blooming. Taiwan Ground Orchids can be grown alongside other perennials such as astilbe, ferns, hostas, and heuchera.
