Philodendrons in the Landscape

Philodendrons are tropical foliage plants belonging to the Aroid family (Araceae). They are part of the popular family that brings us the peace lily (Spathiphyllum), Chinese evergreen (Aglaonema), Flamingo Flower (Anthurium), and even the ZZ Plant (Zamioculcas) There are somewhere between 400-700 species of known Philodendrons. The exact number has not be defined only varying reports from authorities that have different figures. There are also numerous man-made hybrids grown throughout the world. Many are grown as ornamental in the landscape and also as indoor house plants. The name “Philodendron” comes from the the Greek words philo or “love” and dendron or “tree”.

These plants displayed a wide array of beautiful foliage for the landscape. When things are right soil wise and light, they will bear flowers similar to those of Calla Lilies.

Philodendrons due vary on leaf shapes depending on species. The leaf shapes include:

• Heart Shaped
• Oblong
• Long and Narrow
• Deep Lobed
• Arrow Shaped
• Ovate Shaped

These leaves are usually a green color. Some of the leaves may have an underside that is a copper type red tone. They also may have veins that are red in color. When some species are just early in their development, their leaves could be red and then as they mature they turn green. Some hybrids produced today develop deep burgundy colored leaves as they mature - like Philodendron ‘Black Cardinal’. Flowers can range in color from white to yellow and even cream.

One type of Philodendron is the climbing type that can shimmy up a tree. They adapt well to being grown in greenhouses or on the house on a totem and even can grow outside yer round when the climate is right. When covering a tree the Philodendron brings a very tropical look and feel to the landscape like the Central and South American jungles it calls home. Philodendrons can also be found in some Pacific islands, Australia and parts of Asia although they aren’t native to those regions. Instead they were introduced or accidentally escaped.

Tree type philodendrons are a perfect addition to your outdoor living room and garden. With its large bold foliage, this plant really stands out. It is a shrub that grows upright and its leaves are lobes that are deeply divided. It can grow to be 10 feet tall. The trunk of the tree is not very tall and thickens with age. The leaves are glossy and the flowers are greenish tinted white. The best growing conditions are actually the cooler climates where it can get cold. Greenhouses probably are used for the coldest climates.

Potted Philodendrons Indoors

To plant indoors philodendrons do the following:

• Provide temperatures of 60-72 degrees.
• Require less light that other types of houseplants.
• Use pots that drain well.
• Soil mixture of sand and peat moss with loam, and charcoal chopped up.
• You should pot philodendrons in the late part of winter or in the spring.
• Need to place broken crocks or bricks or stones in the bottom of the pot first. This prevents drain holes from being stopped up.
• Use an amount of soil, which allows the plant to sit 1” to 2” below the top of pot. Cover with soil.
• Gently water when you first plant them, and then allow soil to dry before watering. When the plant’s roots get set, the soil can be kept a bit moister.

Remember that in climates such as in the southern region in the USA philodendrons can be propagated in the shade outdoors. They do require a moist soil that is highly rich in nutrients.

Philodendrons outdoors should be fertilized with a granular food once every 3-4 months lightly. Indoors they need their leaves wiped clean with water or water and weak soap mixture to remove dust and insects. Here’s a Philo with “dirty” leaves. You may in some instances also need to wipe them with an appropriate insecticide to keep the insects away.

How to Propagate Philodendrons

You can propagate your own philodendrons by planting cuttings that have at minimum 2 joints on them. Plant them is sandy peat moss mixture. Place them in a greenhouse or a propagating box temperature should be between 70 to 75 degrees F. When the roots get formed, you can move them to bigger pots.
