Phalaenopsis, or moth orchid, is a genus of roughly 60 orchid species (family Orchidaceae) native to southeastern Asia and parts of Australia. Some species are bred for the commercial flower trade, and hybrids with lovely white, purple, and pink flowers are created by crossing them. Many horticultural species and hybrids are popular houseplants and are relatively easy to grow.
Why is it called moth orchid?
Here are six fun facts about phalaenopsis orchids to remember the next time someone asks, “Oh, why do you enjoy orchids so much?” Despite being one of the most common orchid species, Phalaenopsis orchids are everything but ordinary.
Fact #1: Phalaenopsis Orchids Are Nicknamed ‘Moth orchids’
You’ve probably heard Phalaenopsis orchids referred to as “moth orchids” in the past. While it may appear that the term came from the sight of the blossoms, which do resemble a lovely moth taking flight, the real explanation for the appellation is considerably more complicated. The name “phalaenopsis” is derived from the Latin word “phal,” which means “to grow.” “I’m a moth.” Of course, this isn’t a coincidence: the name Phalaenopsis orchids was given by Carl Ludwig Blume because of the moth likeness.
Fact #2: The Phalaenopsis Fragrance Is Most Pronounced at Sunrise
If you’ve ever awoken to the beautiful smell of orchids and wondered why your nose was so drawn to the perfume so early in the morning, it turns out there’s a reason for it. The delicate, sweet scent of a blossoming orchid is best noticeable at morning.
Fact #3: Phalaenopsis Orchids Grow Naturally in Trees
Even though we’re used to seeing Phalaenopsis orchids in pots, they actually grow in trees in the wild. Orchids do not draw nutrients from their host tree, despite the fact that they like to base themselves in trees. Rather than burrowing into the soil, they develop aerial roots that snake around tree trunks and branches.
Fact #4: Phalaenopsis Orchids can get Sunburned
You probably already know not to place your orchid in direct sunlight, but did you realize that doing so can cause your plant to get sunburned? A burnt orchid will have withered, yellowed leaves or develop brown and white splotches instead of developing red. If this happens, immediately transfer your orchid to a shadier location and do your best to keep it hydrated.
Fact #5: Phalaenopsis Orchids are Native to Southeast Asia
If you’ve ever wondered where orchids come from, go no further than Southeast Asia. However, Phals native to the Philippines and Australia can also be found.
Fact #6: Phalaenopsis Orchids Can Take Up to a Year To Flower
The majority of Phalaenopsis take their time to bloom. Fortunately, most plant owners don’t have to wait through this process unless they’re orchid growers. Your orchid should be in the middle of a blooming cycle or have buds ready to burst by the time you buy it.

What does a moth orchid look like?
Moth orchids (Phalaenopsis spp.) are attractive and popular orchids native to tropical Asia’s woods. They feature lovely and long-lasting blossoms in a variety of gorgeous colors, including pink, mauve, yellow, and white, and are frequently given as gifts.
How do you look after a moth orchid?
Remove the orchid from its pot and carefully pick away all of the old bark compost from its roots, gently untangling them if required.
Remove any diseased or dead roots, which are brown, shriveled, mushy, or hollow.
Reduce the remaining healthy roots to roughly 12cm in length (5in). Plump, firm, and silvery-white roots indicate good health.
Re-use the original container if the roots now fit nicely inside. Avoid overpotting into an overly big container; if there is a lot of surplus compost, it will stay wet for too long, rotting the roots.
Fill in the crevices surrounding the roots with fresh orchid compost and keep the plant in the container at the same level it was before. Firm it in with your fingers as you go, especially around the borders. When you pick up the plant by its stem, the container and compost should come with it and not fall away if everything is done correctly. The plant will become unstable if the compost is too loose, and it may injure the new root tips, preventing them from sprouting.
If you cover any roots that are growing out into the air with compost, they will decay.
You may need to add a little cane or two to offer support until the roots have formed in the new container if the plant is unsteady or unbalanced.
Finally, give the plant a good soaking, making sure the entire rootball is wet. Allow the water to drain completely and do not leave the plant submerged.
Caring for older plants
Moth orchids are low-maintenance plants that will continue to grow and flower for many years with little care. Simply keep them warm and in bright light, water them regularly, and repot them every few years. To remove dust, clean the leaves with a moist towel every now and again.
Moth orchids frequently develop roots above the compost that resemble a clambering attempt to escape their container. There’s no need to be concerned, and you shouldn’t try to bury them. Moth orchids are epiphytes, meaning they grow on other plants, most commonly tree branches. These ‘aerial’ roots assist them in clinging to their perch and absorbing nutrients and moisture from their environment in the wild.
What are moth orchids used for?
Many people don’t consider easy-care moth orchids to be houseplants, but with proper care, they may be long-lived companions that provide weeks or even months of beauty each year. Here are seven reasons to keep a few of moth orchids as houseplants.
Few plants can match the elegance and refinement of a lovely orchid in bloom. An orchid, whether on your desk at work or at home, adds refinement and panache.
Despite their exotic appearance, moth orchids are incredibly easy to manage and make an excellent beginner plant if you’ve previously struggled with houseplants. Simply place it in a medium-bright location (where you can read comfortably without turning on additional lighting) and water it every 10 to 14 days. Feel free to fertilize it with orchid fertilizer in the spring and summer to encourage new blooms. That’s it; orchids are that simple.
To express how much you care, give a moth orchid to someone special. Orchids are an exquisite present that lasts far longer than cut flowers, making you appear more caring. Add a little chocolate if your significant other (or soon-to-be significant other!) enjoys it for more oomph.
At work, keep a moth orchid and savor the advantages. Scientific studies demonstrate that simply being in the presence of plants can reduce stress levels, allowing you to be cool, calm, and collected when you’re up against a tight deadline. Other scientific study says that having plants around at work can aid with memory and creativity, thus the moth orchid may be beneficial to your job performance.
Moth orchids take volatile organic compounds (VOCs) from the air as they breathe. What’s the end result? You’re breathing cleaner air that doesn’t include xylene, a pollutant found in paint, air fresheners, ink, and adhesives.
Moth orchids and other houseplants might assist if the air in your home or office is dry. Moth orchid can help relieve dry, flaky skin and chapped lips in the winter by slowly releasing moisture into the air as part of its natural breathing process.
Bonus: The extra moisture in the air can help you avoid as many coughs, colds, and sore throats as possible.
Because the moth orchid reduces tension and anxiety, you will feel happier and more calm. Plants, in fact, have been linked to improved mood, self-esteem, and happiness, according to certain studies.
Can you grow a moth orchid from a leaf?
Ascocentrum, Dendrobium, Vanda, and Ludisia are some of the orchids that respond well to cuttings.
Stem cuttings are the most common way to grow orchids, as they may be used to reproduce all of the species indicated above.
Orchid meristem propagation
Orchids are virtually always propagated by cutting the apical meristem in commercial orchid producers.
The apical meristem is the tip of any new development, and it has the ability to expand into any region of the plant, similar to stem cells.
The meristem is then cultivated in a sterile environment in an agar solution, which feeds the fledgling plant nutrition.
- It necessitates specialized laboratory equipment as well as a sterile atmosphere that is strictly monitored.
To take a stem cutting, first locate a healthy portion of the orchid’s stem.
To put it another way, one that is fat and has a lot of aerial roots.
Cut immediately below each node of aerial roots, leaving a stem above the roots for a new orchid to develop on, or cut between the nodes, leaving a node in the middle of the stem for a new orchid to grow on.
In a closed dish filled of damp sphagnum moss, grow these stem parts. They should begin to root in a few weeks and can be potted out in their individual pots and mixed.
The crucial thing is to keep the stem parts moist. You can either lay them on their sides or plant them upright in the moss.
Orchid propagation from leaf cuttings
Orchids as a genus cannot be propagated from leaf cuttings, although Vandas have been successfully grown from leaf cuttings in the past.
This is usually accomplished by attaching a newer leaf to a short piece of the parent stem.
If everything is done as cleanly as possible and the conditions are ideal, the stem part will occasionally sprout new roots and continue to grow.
Rap the wounded area of the stem with sphagnum moss and a piece of plastic bag until the wound has callused, preventing the parent Vanda from suffering.
Orchids typically do not take to root cuttings on their own, just as they do not take to leaf cuttings.
If a piece of leaf or stem is linked to the root, however, the chances of it developing into a new plant increase considerably.
Let’s imagine you already have a large orchid that is several years old and want to add to your collection.
Let’s pretend this orchid hasn’t developed any aerial roots and doesn’t have any extra leaf nodes on its stem.
If you carefully cut away a leaf, a small section of the stem, and a root or two with a sterilized knife, the separated section of the plant may grow on its own.
Keep in mind that the purpose of this experiment and all further cuttings is to cut the plant, not yourself; you can’t create a new you!
Cover both open areas on both plants with clean sphagnum moss and duct tape until a callus forms after you’ve detached this section from the original.
How do I know if I have a moth orchid?
Phalaenopsis orchids, also known as “moth orchids,” are the most common orchids on the market. Their leaves are usually large, flat, and dark, and they are positioned opposite each other. They have long, tall stems with large, flat flowers that can last three months or more. Their lip is smaller than the petals and is positioned horizontally beneath the column.
What do you do with moth orchids after they bloom?
- Wait until the blooms are no longer blooming. When your orchid blooms, you’ll be left with a flower spike on which the majority of the flowers have fallen.
How often do you feed a moth orchid?
Moth orchids are epiphytic plants, which means they grow on the surface of other plants instead growing in the soil in the wild. While they require humidity, they do not tolerate being overwatered.
Water once or twice a week, preferably with rainwater or boiled and chilled tap water. Every couple of weeks, fertilize with orchid fertilizer or a dilution of other house plant food.
Cut the flower spike back to just above the first node when it has finished flowering. From this point on, your moth orchid should grow a new flower spike.
You can repot your moth orchid when it has finished flowering, but it isn’t necessary. Wait until flowering has ended before disturbing the roots, as this will cause the plants to drop their blooms.
How often do moth orchids bloom?
Phalaenopsis, often known as the “moth orchid,” is one of the longest-blooming orchid genera, with flowers that last anywhere from 2 to 6 months before dropping! Once a full size is achieved, phalaenopsis has been known to bloom twice or three times every year. Cut the stem immediately above the node where the first blossom bloomed after it has flowered for the first time. Within two months, a new blossom stalk should grow from the top node. If you don’t get a reaction or the flower spike goes brown, clip it off near the plant’s base where it first appeared.
