Blue Orchids: Spot the Real from the Artificial in their Splendor

Blue orchids, with their stunning and eye-catching hues, have captivated the hearts of many plant enthusiasts. These rare and exotic flowers possess a unique charm that sets them apart from other orchid varieties. Despite their distinct coloration, blue orchid flowerss are often a subject of curiosity, leaving many to wonder if they truly exist in nature or are the result of human intervention.

In fact, most blue orchids found in florist shops and garden centers are not naturally grown that way. They are usually white orchids that have been dyed blue through a special infusion process. However, a few species do occur naturally in the wild, such as the Boella coelestis from South America’s Andes region. This particular type of blue orchid is known for its striking beauty, but requires expert care and specific environmental conditions to thrive.

To grow blue orchid plants at home, it’s important to understand their preferred growing conditions. Most species thrive in cooler temperatures around 60-70 degrees Fahrenheit, with good air circulation and low humidity. A well-draining potting mix and proper care, including orchid-specific fertilizer, are also essential to ensure the success of these delicate and bewitching flowers.

Blue Orchids Origin and Classification

Blue orchids are a rare and unique variety of orchids that catch the attention of enthusiasts and collectors worldwide due to their stunning blue coloration. They belong to the Orchidaceae family, which is one of the largest families of flowering plants, comprising over 28,000 species across the globe.

While naturally occurring blue orchids are quite rare, several species exhibit blue hues combined with other colors, such as purple or violet. A notable example of a true blue orchid is the Thelymitra crinite or the Blue Lady orchid, native to a small southwestern area of Western Australia. This flower is considered one of the bluest orchids found in the wild.

Another example of a blue orchid species is the Boella coelestis, originating in South America’s Andes region. This orchid challenges even expert growers, as it requires low light and extremely high humidity (80-100%), making it nearly impossible to achieve ideal growing conditions without a greenhouse.

There are also hybrid blue orchids, such as the Vanda blue orchid and the Cattleya blue orchid. These plants have been specially bred to display a broader range of blue tones, making them more accessible and appealing to growers and collectors.

Types of Blue Orchids: Are they real?

Blue Mystique Phalaenopsis Orchids

Phalaenopsis, also known as moth orchids, are popular for their elegance and ease of care. While most Phalaenopsis orchids come in a variety of vibrant colors, finding a true blue orchid in this genus is a rarity. In fact, this is a commercially produced blue orchid, created by infusing white Phalaenopsis orchids with blue dye. The result is a striking, vivid blue color that does not occur naturally in Phalaenopsis orchids.

Dendrobium Orchids

Dendrobium orchid is a diverse genus of orchids with over 1,000 species that can be naturally found in Asia, Australia, and the Pacific Islands. The blue-colored species, such as Dendrobium cyanocentrum and the Blue Dendrobium (Dendrobium bigibbum var. compactum), showcase a range of blue shades along with other accompanying colors. These orchids typically thrive in intermediate to warm environments and require adequate light for proper growth.

Growing and Care of Blue Orchids

To successfully grow blue orchids, one must consider the specific requirements for their environment, which typically includes:

  • Humidity: Many blue orchids thrive in high humidity levels, ranging from 60% to 100%, depending on the species.
  • Lighting: Providing the appropriate lighting conditions is crucial, with each species having distinct preferences ranging from bright indirect light to low light conditions.
  • Temperature: they usually prefer warmer temperatures, but exact requirements may vary between species.
  • Air Circulation: Adequate air circulation is essential to prevent fungal and bacterial issues.

Light Requirements

Blue orchids require bright, indirect light for optimal growth. Direct sunlight should be avoided as it can cause leaf scorching. Providing a location near a window with filtered light through a sheer curtain can help ensure the right amount of sunlight.

Temperature and Humidity

These orchids thrive in temperatures ranging from 60 to 75°F (15 to 24°C) during the day and 55 to 65°F (13 to 18°C) at night. Maintaining a humidity level of at least 50% is important for their growth. To increase humidity, place the orchid container on a tray filled with pebbles and water, or use a room humidifier.

Watering and Fertilization

Water your blue orchids when the growing medium becomes nearly dry, ensuring the plant does not sit in soggy conditions, as this can lead to root rot. Typically, watering is needed once a week. Fertilize the orchid once a month with a general-purpose fertilizer diluted to half the recommended strength for best results.

Potting and Soil Requirements

For optimal growth, use a well-draining and airy growing medium, such as a blend of bark, perlite, and sphagnum moss or peat moss. Blue orchids mostly grow as epiphytes, so a container providing sufficient airflow around the roots is essential. Select a pot with plenty of drainage holes and a size just large enough to accommodate the roots.

Repotting and Pruning

Repotting is required every one to three years, depending on the plant’s growth rate and the condition of the growing medium. Replace the old medium with fresh medium during repotting. To prune, simply cut back flower spikes after they have finished blooming or remove dead leaves as needed. In case of pseudobulbs or rhizomes, remove only the dead or damaged portions and leave the healthy sections intact.


Blue orchids require specific care: high humidity, bright indirect light, temperature control, air circulation, well-draining medium, and proper watering. Regular fertilization, repotting, and pruning ensure healthy growth and longevity of these captivating plants.

Flowering and Fragrance

True Blue Orchids are known for their striking appearance and captivating fragrance.

The scent of these orchids plays a significant role in their survival, as it helps attract various pollinators, including butterflies, bees, wasps, hummingbirds, and beetles. The fragrant blooms generally have bold, bright colors that draw in these pollinators.

Fragrant orchids, tend to emit their scents more strongly on sunny days. This is due to the warming and diffusion of volatile oils within the flowers. Furthermore, these fragrances are known to linger longer in areas with high humidity, while breezy locations may cause them to dissipate more quickly.

Dyed and False Blue Orchids

The ethics of artificially colored blue orchids

While blue orchids are visually stunning and attract significant attention, it’s essential to understand that common phalaenopsis and dendrobium orchids do not naturally produce blue flowers. These popular varieties achieve their blue hue through a process involving the injection of blue dye into the stem, which causes the blossoms to turn blue as they absorb the dyed water.

Some people argue that this practice is unethical, as it involves modifying a plant’s natural appearance for commercial gain. This process can also lead to increased prices compared to their natural counterparts, potentially misleading consumers into believing they are purchasing a rarer, naturally blue variety.

Environmental impact

Aside from the ethical considerations of altering a plant’s natural colors, there is also an environmental impact to consider. The process of dyeing orchids blue involves the use of artificial dyes, which can have adverse effects on the environment if not regulated and managed responsibly.

Additionally, the production and disposal of such dyes can result in pollution and contribute to the depletion of natural resources. Although a single dyed orchid may not seem like it would significantly impact the environment, the magnitude of this effect increases when considering the popular demand for artificially colored blue orchids globally.


Artificially colored blue orchids raise ethical concerns, as they modify natural appearance for commercial gain and may mislead consumers. The dyeing process can negatively impact the environment if not managed responsibly.


Are there real blue orchids?

Yes, real blue orchids exist in nature, although they are relatively rare. For example, there is the Boella coelestis, a blue orchid native to South America’s Andes region.
