How to Plant, Grow, and Care for Queen of the Night Flower

Queen of the Night Flower

The Queen of the Night flower, also known as Epiphyllum oxypetalum, is a stunning and unique plant that is native to Central and South America that belongs to the night-blooming Cereus family of cactus (Cactaceae family). Its large, fragrant, white flowers bloom only at night, making it a popular choice for night gardens and moon gardens.

This stunning night-bloomer is often called the ‘orchid cactus’ due to its delicate and intricate blooms. But don’t be intimidated by this plant’s exotic appearance – with proper care, it can be a wonderful addition to any garden.

Although this plant only blooms once a year, it is very easy to grow! But if you don’t keep an eye out during spring, you may miss out on its blooming fragrant flower. Some may think that this plant’s blooming time is the challenging part of growing this plant, but it’s not!

Interestingly, the Queen of the Night flower has a fascinating pollination process. The plant is pollinated by nocturnal animals, such as bats and moths. The flowers open at night and emit a sweet fragrance that attracts these animals. The animals then transfer pollen from one flower to another, allowing the plant to reproduce.

These plants proliferate and make great houseplants and even outdoor plants if they’re correctly handled.

Through my years of cultivating the Queen of the Night, I’ve come to understand the importance of maintaining a suitable environment. I keep a watchful eye on temperature and humidity levels, mimicking its native tropical habitat.

I make sure to protect it from frost during colder months and provide a gentle misting or place a tray of water nearby to create a humid microclimate, replicating the ideal conditions it craves. Read on to learn exactly how to grow and care for queen of the night plants according to a master gardener!

Queen of the Night Flower Care

Queen of the night flower hails from southern Mexico and the tropical rainforest of South and Central America. Mature plants can grow up to 10 feet tall outdoors. This is a tropical succulent genus often called climbing cacti or orchid cacti.

In its natural habitat, the Queen of the Night typically grows as an epiphyte, nestled within the branches of trees. As your Night Queen grows, you will see that it sends out many long shoots. These are long stems that cling to nearby trees and allow them to grow together in the wild.

The stem, also known as dung, has a small root-like structure that helps in the plant’s ability to support other plants. Thanks to these stems, plants are able to move across the canopy in search of better light.

Over dozens of species and associated hybrids of varying shapes, colors, and sizes exist. They usually have flat, long, non spiny trailing stems. With proper care, they showcase bright, fragrant, and night-blooming flowers in the spring and summer months.

In the wild, their plants grow on trunks or branches rather than developing roots on the ground floor. They absorb the nutrients and moisture they need from the humid environment surrounding them.

In an outdoor landscape, the trailing stems of the queen of the night flower look good in hanging baskets. Despite their common name, this plant does not enjoy dry air and full sun like other cacti species.

This plant does best in shady, warm, and humid spots replicating their tropical forest habitat, making them a great easy-to-grow bathroom plant.

Unless you can offer your queen of the night plant mild temperatures, humidity, dappled sunlight, and an excellent porous potting mix, it’s best to stick with growing it indoors.

This plant likes similar conditions to bromeliads and orchids. When grown outdoors, they should have ample air circulation and sufficient protection from strong winds.

Light

Like most plants, the queen of the night cactus needs light to grow. Direct sunlight in the morning is essential for it to bloom, though it should be kept indirect light afterward.

This plant needs at least 6 hours of bright indirect sunlight, and a south-facing window is best for this indoor orchid cactus. If you choose to grow this plant outdoors, it should be placed in a dappled shade where it can receive enough morning sun.

Soil

The queen of the night plant grows well if it’s provided with the right soil type. This plant needs well-drained and airy soil that can hold moisture and is slightly acidic with a pH of around 5.5 to 6.5.

Make sure to avoid dry soil at all costs. Apart from the mentioned requirements, you can step up your soil game by adding peat moss, perlite, and orchid bark mix. You can also opt for sandy soil.

Water

While Queen of the Night flower may appear delicate, it is a resilient plant and can tolerate periods of drought, and does not require frequent watering.

During its active growing season, I keep a watchful eye on the top two inches of the soil, waiting for it to dry out before giving it a thorough watering. When potted, you’ll need to water slowly, wait for the water to flow out from the bottom, and then pour the excess from the tray to avoid water accumulation.

Water once or twice during the growing season in spring and summer. And water less during fall and winter -keep the soil from drying out. Choose rainwater or distilled water over tap water as it contains mineral salts that can sauce soil compaction.

Temperature and Humidity

This plant is distributed throughout semi-desert, tropical, and subtropical regions with intense sunlight, scarce rainfall, and hot temperatures.

This plant’s ideal temperature for growth is 68 – 95 degrees Fahrenheit. Lower than 50ºF or higher than 95ºF slows the plant’s growth, and dormancy begins. Make sure to avoid placing it in ventilated areas where drafts occur.

The queen of the night flower thrives best in normal humidity levels at most homes. If your home’s humidity ranges between 40-50%, you can grow it indoors.

If you live in a dry climate, consider placing it on a tray of pebbles filled with water to increase humidity levels. You can also mist the plant regularly to provide additional moisture.

This is mostly recommended if the air at home is too dry, but humidity is not a common problem while growing this night cactus.

Fertilizer

Fertilization is critical in ensuring that your Queen of the Night flower blooms. Fertilize once a month during the active growing season.

Use phosphate-potassium fertilizer before and after blooming and nitrogen fertilizer during seedling. The fertilizer concentration should always be as low as possible. Applying low-concentrate fertilizer several times would be best instead of using a high concentration.

If the base grows slowly and is yellow, it may be a sign of too much fertilizer, and fertilization should be stopped immediately.

Pruning

This plant requires only a little pruning. Removing white flowers and branches should promote healthy growth. You can prune it annually after the plant blooms. It’ll help remove any yellow leaves, dead flowers, or stems and shape the plant properly.

When pruning, use clean, sharp pruning shears to avoid damaging the plant. You can also propagate the plant by taking stem cuttings and rooting them in water or soil.

How to Propagate Queen of the Night Flower

If you’re looking to grow your own Queen of the Night plant, propagation through cuttings is a simple and effective method.

The primary propagation method for the queen of the night flower is division. Here’s how to create new plants:

Step 1: Cutting the Stem

The first step in propagating your Queen of the Night plant is to cut a stem from the parent plant. Choose a stem that is about 4-6 inches long and has no flowers or buds.

It’s important to use a sharp, clean pair of pruning shears to make the cut. This will ensure that the stem is not damaged and has the best chance of developing roots.

Step 2: Preparing the Cutting

Once you have cut the stem, it’s time to prepare it for planting. Remove any leaves from the bottom half of the stem. This will help to prevent any rotting or fungal growth.

Next, dip the cut end of the stem into rooting hormone. This will encourage the stem to develop roots once it is planted. Place it in a cool dark place for the next couple of days, allowing it to callus.

Step 3: Planting the Cutting

After preparing the cutting, it’s time to plant it in a potting mix. Choose a pot that is slightly larger than the stem and fill it with a well-draining cactus or succulent potting mix.

Make a hole in the potting mix and gently place the stem into the hole. Firmly press the potting mix around the stem to ensure that it is secure.

Step 4: Caring for the Cutting

Once you have planted the cutting, it’s important to take good care of it. Water the cutting sparingly, as overwatering can cause the stem to rot. Do not water the plant for the next two weeks until it settles

Keep the cutting in a warm, humid area, as this will encourage root development. You can cover the cutting with a plastic bag to create a mini greenhouse and help to maintain the humidity levels.

Once it has settled, continue with regular care.
