What’s Unique About Philodendron gloriosum?

The Philodendron gloriosum plant is a tropical beaut that may have been easily penetrating the market with its attractive set of foliage, crawling habit – which makes for a perfect ground cover, and rarity due to inability to produce many seeds. The plant is therefore highly sought by many home gardeners and plant enthusiasts.

Philodendron gloriosum plants are native to Colombia but have been extensively grown in other tropical regions. The plant may be found widely distributed in Mexico, Peru, Ecuador, Brazil, and other parts of Central America. Characterized by the plant’s crawling rhizome, the anthurium gloriosum creeps horizontally across the ground. 

Philodendron gloriosum Care

The Philodendron gloriosum plant care involves the use of an appropriate growing medium, a temperature of at least 65-85°F (18 – 29°C), and a fairly humid environment. If you already have some knowledge about the basics of growing common houseplants, then you can easily follow through the anthurium gloriosum care.

Light 

Many observations indicate that the Philodendron gloriosum light requirements are bright, indirect light but it can also thrive under semi-shaded conditions. One thing to remember, however, is that exposure to direct full sun must be avoided, as this can cause the delicate leaves to scorch.

Generally, the anthurium gloriosum light needs vary with the location from where you choose to grow the plant. For indoors, have the plant placed near an east-facing window so it will have access to plenty of bright, filtered light. For outdoors, the plant must be able to receive some afternoon shade in order to prevent damage to the foliage due to leaf burn.  

Watering 

Philodendron gloriosum watering must be thorough in order to maintain the soil damp but not soggy. The best way to check your plant’s watering needs is to stick your finger into the pot and see if the top inch of the soil feels dry to the touch.

Avoid overwatering as this can do more damage than good. Note that an overly wet soil makes the plant vulnerable to root rot. Water anthurium gloriosum thoroughly once or twice a week, depending on dampness. Increase watering during summer and reduce during winter. It may be beneficial to allow the pot to dry out in between watering cycles.

Temperature 

The ideal Philodendron gloriosum temperature range is between 65 – 85°F (18 – 29°C. If they are grown outside, be sure to bring them inside upon the onset of winter because they do not possess a low-temperature tolerance and thus quite vulnerable to freezing injury. Several reports indicate that the plant thrives well at USDA hardiness zone 11. 

At night, the temperature for anthurium gloriosum should be around 60 – 70°F (16 – 21°C) for optimum growth.

Pro tip: When the plant is placed near a window, invest in a good curtain so that the plant may also be protected from drafty cold weather.

Humidity

Being a tropical plant, the Philodendron gloriosum humidity requirements are slightly higher, usually around 60-80%. However, they can also tolerate a lower humidity level such as <50%.

If you feel that your air moisture at home is low, you may opt to use a humidifier or set a pebble tray. You can also mist the plant from time to time to increase air saturation.

Maintaining the ideal humidity for anthurium gloriosum may be challenging indoors. But outside, the natural ambient condition may already do the job for you. You may also group your plants together for this can help make the surrounding become more humid. 

Soil 

Similar to most aroids, the Philodendron gloriosum soil should be well-draining and rich in organic matter. A commercially bought orchid mix will do just fine but you can also concoct your own by combining an equal proportion of fresh garden soil, peat moss, and perlite for an improved texture and aeration.

The optimum ph level for anthurium gloriosum is between pH 5 to 8 (acidic to basic). Avoid a clumpy soil mix as it may impede root growth and may easily become soggy with watering. Another ingredient that you can also add to the potting soil for anthurium gloriosum is charcoal or biochar, which is said to remove toxins from the soil and promote healthy growth. 

Fertilizer 

Generally, the growing season falls during summer and spring. This is often the best time to apply fertilizer for anthurium gloriosum. Use liquid fertilizer at half-strength at a monthly interval, and reduce it later during winter.

A balanced fertilizer ratio such as 14-14-14 is a key for growth and overall plant health. So be sure to invest in a good Philodendron gloriosum fertilzer and refrain from using cheaper ones as they tend to accumulate in the soil over time.

You can also invest in natural amendments like vermicast and plant juices, which are equally beneficial for both the plant and soil microbes. 

Potting & Repotting

A rich and well-draining potting mix is a good starting point for repotting anthurium gloriosum. If the plant has become root-bound or if the roots are already appearing from the base of the pot, this signals the need for repotting.

Pro tip: For Philodendron gloriosum repotting, choose a narrow container that’s twice the original pot size with sufficient drainage holes. Fill in with half of the potting mix and place the plant gently in the center. Fill in with the rest of the potting soil and firm up from the base of the plant. Water thoroughly, especially for the first two weeks.

Pruning

Make it a habit to trim unwanted plant parts such as spent leaves, stems, and flowers (if there are any). However, being a slow-growing plant – which takes about a month to develop a new leaf – the Philodendron gloriosum pruning is done only when it is already taking up too much space or if the plant is showing signs of insect infestation and disease.

Pro tip: Begin cutting anthurium gloriosum from the stem’s base, selecting only those that show signs of withering, yellowing, decaying, and other symptoms of an impending disease. Be sure to water the plant thoroughly afterward in order to minimize stress.

Propagation 

The most commonly used method of Philodendron gloriosum propagation is by using stem cuttings. First, find a healthy-looking stem that is at least 3 to 6 inches long with some leaves that are still intact. Cut in between the joints or internode using sterile shears. Plant the cuttings on rich damp soil. Water as often and place it on a spot that receives lots of indirect light. 

In 3-4 weeks’ time, you should be able to see an established plant. Another way to propagate anthurium gloriosum is by taking portions from the rhizome, preferably one with roots already, and then planting as usual.

Common Problems of Philodendron gloriosum

The most common Philodendron gloriosum problems are caused by improper cultural management. For example, the yellowing of the leaves may either be caused by overwatering and underwatering. Deformed foliages may be caused by too little light and high temperature.

Knowing some of the problems with anthurium gloriosum will give you a head’s up on what to expect and do. 

Pests 

The most common Philodendron gloriosum pests are spider mites, scale bugs, mealybugs, and whiteflies. They damage the foliage by feeding and taking nutrients that can otherwise be used for growth and development. Thus, leaving a plant with stunted growth, necrosis, and decaying parts. The insects may also create holes in the leaf tissue that may become an entry point for fungal and bacterial infection. 

Treat your infested anthurium gloriosum by rapid water expulsion, you can also use horticultural oils such as neem oil either by spraying or wiping the leaves off with any insects and sooty molds. As a preventive measure, be sure to use sterile tools and maintain an optimum temperature and humidity.

Diseases 

Overwatering and humidity level that is beyond the optimum are two of the most common culprit for an increased incidence of Philodendron gloriosum diseases. For example, if the plant is allowed to sit on soggy soil for a long period of time, it may develop root rot, which later causes the yellowing of the leaves.

Moreover, bacterial leaf spots may also affect your anthurium gloriosum. If you suspect that your plant is already infected, isolate it from other plants. Prune the infected plant parts and other debris, be sure to use sterile equipment, and invest in pathogen-free seed and propagules.

Growing Problems 

Growing Philodendron gloriosum whether indoor or outdoor may have its own problems from time to time. But the first step in tending to a sick plant is to investigate first what causes the symptoms and see if it is biotic (due to the presence of pests and pathogens) or abiotic (temperature, light, and humidity) in nature.

Growing problems arising from pests and diseases are shown through symptoms like premature senescence, yellowing of leaves, decay, and light to dark brown spotting. With this, be sure to immediately remove the infected parts. In severe infections, you may opt to use fungicides and insecticides but use them with great precaution

Toxicity of Philodendron gloriosum

While the anthurium gloriosum is celebrated for its beauty, there is some precaution needed when tending to this plant because of the toxicity it possesses.

Sadly, the plant is toxic to both humans and animals. And if ingested, may cause irritation of the throat, swelling of the mouth, and even seizure.

For Humans 

The Philodendron gloriosum is reportedly toxic to humans, and small children are particularly at risk. If ingested in large amounts, several symptoms that may be observed include cramps, swelling and irritation of the mouth, oral blisters, and in most severe form, kidney failure and seizure.

Choose a strategic location that is out of reach of children and pets. Preferably on elevated spots such as tabletops, window sills, and corner cabinets – or better yet, grow your anthurium gloriosum outside. If any of the mentioned symptoms occur, immediately seek help and call for a physician to check on your child.  

For Pets 

If you have lots of pets at home, it may be best to choose a different plant to grow inside. This is because animals are harder to control when they come in a bunch and your best effort may not be enough to prevent them from chewing parts of your anthurium gloriosum plant. 

If any of your furry friends have happened to ingest some parts of the plant, symptoms that may appear are panting, pawing of the face, mouth blisters, blood in urine and stool, and restlessness. If you see any of these symptoms, consult your veterinarian so your pet gets treated immediately.    

Philodendron gloriosum Appearance

It is no doubt that the Philodendron gloriosum appearance becomes a key factor as to how this particular aroid has been on top of the most highly coveted plants by collectors, home gardeners, and plant enthusiasts. With its massively green and heart-shaped foliage, the anthurium gloriosum is a real stunner. 

Foliage

The heart-shaped foliage of Philodendron gloriosum is characterized as massive, deep green, and adorned with creamy white venation. With a velvety texture, the plant is pleasant to look at as it is touched. The plant’s crawling or creeping habits is actually perpetrated by the stems that grow along the ground surface.

Each leaf of the anthurium gloriosum will only take form for about a month, hence categorized as a slow-growing cultivar. You can easily spot an issue by simply looking at the leaves, as they would usually turn yellow when they are waterlogged or if the soil becomes nutrient deficient.  

Flowering

Upon maturity, you’ll notice that the plant begins to produce white flowers that come with a spathe that encloses a spadix. This flower formation is relatively common among aroid species. From a botanical perspective, the anthurium gloriosum flower is called an inflorescence. 

In a tropical environment, where the plant originates, more flowers are produced in response to competition for light, water, and nutrients. But in an indoor setting, blooming rarely occurs and it isn’t much of a concern when the anthurium gloriosum is grown as a foliage plant.

You can expect the Philodendron gloriosum flowering to occur from around May to July.

Size and Growth

The size of Philodendron gloriosum leaves can grow up to about 36 inches long. Especially when all of the growing conditions are at optimum. However, expect the plant to have a relatively slow growth rate. That is because it takes about 1-2 months before the plant can form new leaf flushes. But the plant height in general can reach up to 0.9 meters or 35 inches tall.

Pro tip: Take advantage of the growing season if you want your anthurium gloriosum to increase in size. Apply a balanced liquid fertilizer once a month, and place the plant under bright, indirect light. 

Philodendron gloriosum Fragrance

The foliage has no scent of any kind, but the flowers (which rarely occur indoors) may emit some, especially when in full bloom. However, there is little information to actually distinguish the Philodendron gloriosum fragrance.

In spite of that, a smell can also tell you if there is something wrong with your plant. For example, a bacterial infection would create tiny, water-soaked areas that form a lesion – later on emitting a strong and unpleasant odor. 

The anthurium gloriosum’s disease may be addressed by removing infected plant parts, wiping the leaves with rubbing alcohol and applying horticultural oils such as neem oil and citronella.  

Suggested Uses for Philodendron gloriosum

Due to its large, deep-green leaves and striking venation, the Philodendron gloriosum certainly makes for an attractive foliage plant. Thus, the plant is grown indoors to accentuate any home and to fill the empty dull spaces with its tropical vibrancy. 

The anthurium gloriosum plant is also notable for its creeping habit, and thus often used as well as ground cover in tropical gardens. And if planted in large pots, the plant is a stunning terrestrial specimen.

In addition, the plant’s air purifying characteristic attracts many home growers as each massive leaf of Philodendron gloriosum is known to reduce pollutants such as carbon dioxide.
