What is a Philodendron Erubescens

Philodendron Erubescens

Philodendron Erubescens are tall, vining plants that are tropical and native to South America. In their native environment, these plants can grow as tall as 60 feet. When grown as a houseplant, they will remain much smaller and grow to around 12 feet. Many people will keep their plant in a small pot, which will stunt its growth and allow it to remain about 36 inches in height. You can also control the size and shape of your plant with regular pruning.

The Philodendron Erubescen can also be grown outdoors in the right climate. If you live in USDA zones 10 to 11, your philodendron will thrive outside. The species is an aggressive climber which produces long vines and has narrow, dark green leaves. The foliage has a red underside which is where the plant gets its common nicknames; blushing philodendron, red leaf philodendron, and imperial red. These plants are very popular due to their stunning waxy leaves. They can be grown in a hanging basket or on a windowsill or shelf and have cascading vines that look great.

The Philodendron Erubescens can convert to a fully epiphytic state as it climbs taller rainforests trees. These plants will survive even if their connection to the earth is severed. Erubescens are a flowering perennial that produces a deep red flower during the late spring and summer months.

Like all philodendrons, the Philodendron Erubescens is toxic to people and animals if ingested. Keep this plant away from small children and pets. If you decide to plant this variety of philodendrons outdoors, ensure livestock can’t reach it as the plant is poisonous to cattle and horses.

How to Care for a Philodendron Erubescens

Philodendron Erubescens Care

Philodendron erubescens are prized by tropical plant collectors and have some specific care needs. These plants aren’t as drought-resistant as other philodendron species, so they shouldn’t be neglected. You’ll also need to keep your plant warm and away from drafts. Here are some care tips to help you grow a healthy and thriving Philodendron Erubescen plant:

Sunlight needs

The Philodendron Erubescen grows in partial shade as it originates from the rainforest and grows as part of the undergrowth, overshadowed by taller trees. As a result, these plants don’t like bright sunlight, and their foliage can get sunburnt quickly. If your Philodendron Erubescens leaves have started to turn yellow, it may be in too bright a light. When brown patches develop on the leaves, this is an indicator of sunburn. Be aware that your plant can also burn through glass, so don’t leave your philodendron on a hot windowsill.

Watering Requirements

The Philodendron Erubescen needs slightly more water than other species of philodendron. You can water your plant when the topsoil starts to grow out. There is no need to check that 2 inches of soil have dried, as is recommended with other philodendrons. As long as the surface feels dry, you can water your plant.

These plants are relatively tolerant of drought but can suffer if they are overwatered. When the soil becomes waterlogged, the plant is likely to suffer from root rot, which can be fatal. If you overwater your plant, the foliage will begin to turn yellow.


The Philodendron Erubescen prefers to grow in soil that’s loamy, well-drained, and rich in nutrients. These plants don’t do well in compact soil. You can add some perlite or sand to your pot to create the right consistency. It’s also worth testing the soil’s pH range. These plants grow best in soil that has a pH of between 5.6 to 7.5.

As these plants like to climb, you can use a moss pole to support and train your philodendron.


The Philodendron Erubescen isn’t very cold resistant and doesn’t like dramatic changes in temperature or drafts. These plants grow best when the temperature is at least 55F. AS the Philodendron Erubescen is a tropical plant, it prefers temperatures to be nearer 80 degrees but can cope with cooler nights. Likely, you won’t need to worry too much about the temperature if you’re keeping your philodendron as a houseplant. These plants do well at room temperature.

If you’ve moved your plant outside in the summer, ensure you bring it back indoors in the fall and winter. Frost can kill philodendrons.


Philodendron Erubescen loves high humidity of at least 50%. This can be achieved by placing your plant in the bathroom or kitchen, as these rooms naturally have higher humidity.

Alternatively, you can mist your plants daily using a spray bottle that produces a fine spray. Group tropical plants together and place a tray with water and pebbles underneath the plants. This will help to increase the humidity surrounding your plants.


You can fertilize your plant once a month using a standard houseplant fertilizer.


Philodendrons don’t require regular pruning but can be trimmed slightly to stop them from getting too large. It’s best to prune your plant either in the spring or fall. You can remove leaves that are dead, damaged, or have turned yellow throughout the year.  You can propagate a Philodendron Erubescnes with a good cutting.


Philodendrons are pretty pest resistant but can be affected by insects such as spider mites, mealybugs, and aphids. It’s best to treat your plant as soon as possible to avoid infestation. You can use neem oil or an insecticidal spray to get rid of pests.


Philodendron Erubescen is a beautiful tropical plant that has red undersides of its leaves. This plant is pretty easy to care for. It needs slightly more water than other species of philodendron, should be kept in the partial shade, and provided with the correct humidity.
