The umbrella tree, whose formal name is Schefflera arboricola, is a bushy, compact plant in the ginseng family (Araliaceae Juss.). The plant comes from places in Southeast Asia like Taiwan, southern China, and Malaysia. It can also be found in New Guinea and other parts of the South Pacific. It can now be found in parts of Queensland in the northern, tropical parts of Australia. These plants are also known as the Australian ivy palm, the parasol plant, the Dwarf umbrella tree, the Umbrella plant, the Chinese evergreen, the Trinette, the Gold Capella, the Amate, the Miniature umbrella tree, the Hawaiian elf umbrella, the Four-finger tree, the Octopus tree, the Finger tree, the Amate tree, and the Arboricola.
The genus name “Schefflera” comes from the name of a German scientist and botanist who worked in the 18th century and made important advances to the field of botany. “Arboricola” comes from the Latin words “arbour,” which means “tree,” and “cola,” which means “inhabitant” or “dweller.” The word “arboricola” means “tree-dwelling” or “inhabitant of trees,” which is a good way to describe this plant since it usually grows as a small tree or bush. The shiny, dark green leaflets on each leaf stalk spread outward in the shape of an umbrella, which is how it got its popular name, “Umbrella Tree.” Some types may have leaves that are speckled with white or yellow spots.

Plant Description
The umbrella tree is an evergreen tree that grows quickly and is compact and bushy. It is usually about 4 to 8 feet (1.2 to 2.4 meters) tall when grown indoors and 10 to 25 feet (3 to 7.6 meters) or more when grown outdoors. The plant grows next to streams, in wet forests, in low woods, along shaded edges, in wet swamps, and in damp open woods. For indoor plants, use potting mix that drains well and has organic matter in it. It can grow in different types of dirt outside as long as it drains well. People in the area sometimes gather the plant in the wild to use as medicine. The plant is also sometimes grown as a hedge and is often grown as a decorative plant, both outside and inside. It is mostly grown as a houseplant for decoration and isn’t usually used in cooking. In fact, many parts of the Umbrella tree are poisonous if people or animals eat them, like the leaves and roots. Because of this, the Umbrella tree shouldn’t be used for cooking or other culinary uses.
Appropriate growing environment for Umbrella tree
To provide an appropriate growing environment for an Umbrella Tree, you should aim to replicate its natural habitat as closely as possible. Here are some key factors to consider:
- Light: When grown indoors, umbrella trees do best with bright, indirect light. Its leaves can get burned if you put it in full sunlight. If you’re growing it outside, pick a spot where the sun is blocked or spread out. It can handle some morning or late afternoon sun in mild areas.
- Temperature: For best results, keep the temperature inside between 65°F and 80°F (18°C and 27°C). Do not let cold drafts or temperatures below 50°F (10°C) hit the plant. In the outdoors, the umbrella tree does well in USDA hardiness zones 10 through 11. It can’t stand frost, so make sure the temperature stays above freezing.
- Humidity: This plant does best when the humidity is mild to high. If your home’s air is dry, you could use a humidity tray, a fan, or mist the plant often to add moisture.
- Watering: Don’t give your Umbrella Tree too much water. After you water, let the top inch (2.5 cm) of dirt dry out. Root rot can happen if you water too much, so make sure the soil drains well. Fill up the saucer under the pot with water and then empty it.
- Soil: For indoor plants, use potting mix that drains well and has organic matter in it. It can grow in different types of dirt outside as long as it drains well.
- Pot Size: If the roots of your Schefflera get too crowded, you should repot it every two to three years. Pick a pot that is a little bigger so that it can grow.
- Fertilizing: In the spring and summer, every 4 to 6 weeks, give your Umbrella Tree balanced liquid manure. During the fall and winter, fertilize less or not at all.
- Pruning: Cut back the plant to keep it in the shape and size you want. You can cut back taller plants or get rid of leaves that are dying or turning yellow.
- Pests and Diseases: Keep an eye out for spider mites, mealy bugs, and scale insects, which are all popular weed eaters. Take care of any pests right away. To avoid fungus diseases, make sure there is good air flow.
- Support: Putting stakes in your Umbrella Tree will keep it from falling over if it gets too tall and heavy at the top.
Roots
The umbrella tree usually has a fibrous root system, which means it has a web of thin, fine roots that grow from the base of the stem and go in different directions. This kind of root system works well to hold the plant in place and take in water and nutrients from the dirt. Most of the time, the roots are light to dark brown and feel like wood or fibers. These roots are designed to go deep into the ground and hold the plant in place. The roots’ depth can change based on how old the plant is, the size of the pot, or where it is planted. Because they are usually grown in pots, indoor umbrella trees have roots that aren’t very deep. When plants are outside, their roots may go deeper into the ground. The roots hold the plant firmly in place in the dirt, making it stable. They take water and important nutrients from the dirt and send them to other parts of the plant.
Stem
People often call the Umbrella tree’s main stem “the trunk,” even though it’s not as thick and hard as the trunks of big trees that grow outside. Instead, especially in younger plants, it is more likely to be thin and bendy. As the plant grows older, the stem might get a little thicker, but it still looks pretty thin. The umbrella tree is known for the way its branches are arranged in a way that looks like the spokes of an umbrella. Multiple side branches grow from the main stem and spread out in a whorled or umbrella-like pattern. These stems can be pretty long and thin, and they may have more than one leaf on them. Depending on the type and how it is grown, the tree can grow to different heights and in different ways. Indoor umbrella trees are usually smaller and more compact, so they can be used as houseplants. Outdoor types, on the other hand, may get taller and look more like trees as they grow.
Bark
The bark of smaller umbrella trees is usually smoother and may look a little glossy or shiny. It might be light to medium brown in color and feel pretty soft to the touch. As the plant grows older, the bark might get a little rougher. Different kinds and types of umbrella trees can have bark that is a different color. Most of the time, it’s between light and medium dark, but the exact color can change. Some types may have slightly grey or brown tones. The bark doesn’t usually have clear designs or markings on it like the bark of some tree species does. Instead, it tends to look more uniform, with only small differences in color and structure. Especially on smaller plants, the bark isn’t very thick. It doesn’t get the rough, thick bark those most big trees outside do.
The bark of the tree may change as it gets older. The skin might get a little rougher, and small cracks or creases might show up. On the other hand, its bark doesn’t usually get the deep furrows or noticeable ridges that you see on the bark of some larger tree types. Sometimes, the bark on older Umbrella trees is stronger and a little rougher than the bark on younger trees. The species, variety, and growing factors can all have an effect on this. The wood on indoor umbrella trees is usually smoother and thinner because they are grown as houseplants and are smaller. Outdoor types, on the other hand, may have more changes in the look and feel of their bark as they get older.
Leaves
These are compound leaves, which mean they are made up of many smaller leaflets that are grouped along a central stem, also called a petiole. There are usually between 7 and 16 leaflets on each leaf, but the exact number can change based on the species and variety. Leaflets are often lance-shaped or ovate, which means they are long and have a pointy or smooth tip. The shape can be a little different between species and varieties, but this is where it usually goes. The leaves’ sizes can change based on how old the plant is and how it’s growing. They are usually about average size, with leaves that are fully grown being about 2 to 4 inches (5 to 10 centimetres) long. The sides of the leaflets are usually smooth, with no teeth or serrations. This helps make the leaves look more delicate and graceful as a whole.
It looks like the leaves are a little shiny because their surface is smooth and glossy. The feel is mostly leathery and strong. There are different kinds and varieties that can have different coloured leaflets. Different shades of green, from light green to dark green, are common colors. Some types of plants may have leaves that are speckled with lighter or darker green spots or lines. The leaflets have big veins that run straight to the midrib, which is the leaflet’s main vein. The venation is usually raised on the leaflet’s upper side, giving it a rough look. Each leaflet has a thin stalk that connects it to the main stem, or rachis. The petioles on the leaves let them bend and adapt to changes in air and light flow.
It depends on the species and type of umbrella tree that the leaves are arranged in a pinnate or palmate way. The leaflets are lined up along a center axis in the pinnate arrangement, which looks like the structure of a feather. In this type of design, the leaflets spread out from a central point, making it look like a hand’s fingers. Along the rachis (central stem), the leaflets are connected one after the other. In other words, they are not straight across from each other on the stem; instead, they are spaced out. When they first come out, the youngest leaves are often a lighter, brighter green. As they get older, they get darker. These different leaf colors can make an attractive difference in the foliage.
Flower
The flowers are grouped in an inflorescence, which is a group of flowers. Depending on the species, the flower head is usually a panicle or raceme. The flower head may hang down in some species, but it may stand straight in others. Most flowers are small and not very showy. Most of the time, they are greenish-white to yellowish-green in color. Each flower is made up of five small blooms and is usually less than half an inch (1 centimetre) across. Each flower has five petals, some of which may be slightly joined together at the base. The flowers are usually long and narrow, and they look like tubes or bells. The flowers have radial symmetry, which means they are actinomorphic. Most flowers have radial symmetry.
The flowers of an umbrella tree are usually dioecious, which means that each plant has either male or female flowers. The male reproductive organs of flowers are called stamens, and they make pollen. The female reproductive organs of flowers are called pistils, and they hold the ovules. It’s not known that umbrella tree flowers have a strong or noticeable scent. The leaves, not the flowers, are what make them so appealing. Trees get pollinated by bugs like bees and flies in their natural environment. They may not make seeds when growing indoors, though, and they don’t depend on bees to pollinate them.
Fruits
Most umbrella tree fruits are small and round, measuring about 1/4 to 1/2 inch (0.6 to 1.3 centimetres) across. They look like little drupes or berries. Different kinds and varieties of fruits have different colors, but most of the time they are green when they first grow and turn red or orange as they get older. The fruit looks kind of shiny because its skin is thin and smooth. Most of the time, it doesn’t have any visible fuzz or hairs on it. Some plant types make fruits that birds and other animals eat, but they are usually not meant to be eaten by people. Interestingly, people don’t usually eat the fruits; they’re grown for their looks rather than as a food source.
Seeds
It looks like a bean, but the umbrella tree seeds are small and oval. Different kinds and varieties of seeds can be a little different size, but most are less than 1/4 inch (0.6 centimetres) long. Umbrella tree seeds can be any color, but most of the time they are brown, black, or a color that looks like dirt. The exact shade may rely on things like the species and how mature the seeds are. There is a seed coat around each seed, which is the top protective layer. There are times when the seed coat is very thin and smooth. When the seed sprouts, it usually makes one or two cotyledons, which are seed leaves. These cotyledons are the first leaves to grow from the seed. They feed the young seedling until the real leaves grow.
Varieties of Umbrella tree
The Umbrella tree has several varieties and cultivars that offer a range of sizes, leaf colors, and growth habits. Here are some popular varieties of the Umbrella tree:
- Schefflera arboricola ‘Amate’: This type has bushier growth and leaves that are bigger and shinier green. It is popular for gardening both inside and outside because of its lush leaves.
- Schefflera arboricola ‘Gold Capella’: The centers of the leaves on this variety are bright green, and the edges are yellow to gold. It makes a big difference between indoor and outdoor settings.

- Schefflera arboricola ‘Janine’: The leaves on this type are smaller than those on the standard Schefflera arboricola, which makes it an easier to care for houseplant.
- Schefflera arboricola ‘Luseane’: The cultivar “Luseane” is known for its beautiful leaves with deep serrations. It looks different from other types in a very noticeable way.
- Schefflera arboricola ‘Tricolor’: People love this type because its leaves are three colors: green in the middle, creamy white around the edges, and pink or red spots on them. It’s a beautiful way to add color to inside areas.
- Schefflera arboricola ‘Nora’: The “Nora” variety has small, closely-spaced leaves and a tight growth habit. This is a great option for small rooms or displays that sit on a table.
- Schefflera arboricola ‘Victoria’: There are white and green designs on the leaves of this cultivar, which makes them look beautiful indoors.
- Schefflera arboricola ‘Compacta’: This type grows more closely together and has smaller leaves, as the name suggests. It can be used in small spaces or as a plant on a table.
- Schefflera arboricola ‘Bonsai’: This type is often grown as a bonsai tree, which looks like a small Umbrella tree with neatly cut branches and leaves.
