Overview of Phalangium elatum (Aiton) Redouté
Phalangium elatum (Aiton) Redouté, also known as the towering spider-orchid, is a species of orchid that belongs to the family Orchidaceae. This plant is primarily found in the southern regions of Australia, including Victoria, South Australia, and Tasmania, where it grows in heathland and open forests. The plant was first described by William Aiton, a Scottish botanist, in 1789, and later re-described by Pierre Joseph Redouté, a Belgian botanist, in 1802.
Appearance of Phalangium elatum (Aiton) Redouté
The towering spider-orchid gets its name from its tall and slender stem, which can grow up to 1 meter in height. The stem produces several green leaves that are narrow and lance-shaped. The plant also produces a single flower that is large and showy, measuring up to 10 cm in diameter. The flower has a dull red or pink color and is shaped like a star, with a central column surrounded by a ring of petals. The flower's petals are narrow and twisted, resembling spider legs, which gives the plant its common name.
Uses of Phalangium elatum (Aiton) Redouté
Despite its striking appearance, the towering spider-orchid does not have any known medicinal or culinary uses. However, it is highly valued as an ornamental plant in gardens and parks. Many horticulturalists and orchid enthusiasts cultivate this plant for its beauty and novelty.
Moreover, the towering spider-orchid plays a vital role in the ecosystem as a pollinator attractor. The plant's large and showy flower attracts a range of pollinators, including wasps, flies, and beetles, which visit the flower to collect nectar and pollen. In doing so, these insects facilitate cross-pollination, which is crucial for the plant's reproduction.
Conclusion
Phalangium elatum (Aiton) Redouté is a unique and striking species of orchid that is primarily found in southern Australia. Its tall and slender stem, green leaves, and large, spider-like flowers make it a popular ornamental plant. Additionally, the towering spider-orchid's role in pollinator attraction highlights its importance in the ecosystem.

It can tolerate direct sunlight but may require some shade during the hottest parts of the day to prevent scorching. In areas with high summer temperatures, it is advisable to grow the plant in partial shade or protect it from the afternoon sun.
Temperature Requirements
Phalangium elatum (Aiton) Redouté grows best in temperatures between 18°C to 25°C (64°F to 77°F), but can tolerate temperatures as low as -2°C (28°F) and as high as 40°C (104°F). It prefers moderate temperatures and can suffer in extreme heat or cold. In areas with harsh winters, it is advisable to protect the plant from frost or bring it indoors.
Soil Requirements
The plant Phalangium elatum (Aiton) Redouté prefers well-draining soil that is rich in organic matter. It can grow in a wide range of soils, including sandy, loamy, or clay soils, as long as they are well-draining. The soil pH should be between 6.0 and 7.5; it can tolerate slightly acidic or alkaline soil. The plant can be grown in pots or directly in the ground.
Cultivation Methods:
Phalangium elatum is a hardy and low-maintenance perennial plant that is easy to cultivate. It prefers well-draining and moist soil with a pH range of 6.5 to 7.5. This plant requires full sun to grow to its full potential, ensuring it has at least six hours of sunlight daily. Make sure to plant it in an area with good air circulation to prevent diseases.
Watering Needs:
Phalangium elatum requires regular and consistent watering during its growing season. Water the plant deeply and thoroughly, making sure the soil is evenly soaked. However, avoid over-watering as it can cause root rot. In winter, reduce watering to prevent the soil from becoming too wet and causing the plant to rot.
Fertilization:
This plant requires regular fertilization during its growing season to ensure optimum growth and blooming. Use a complete and balanced fertilizer, preferably one with a higher amount of phosphorus, which promotes flower production. Fertilize after every two to three weeks but avoid over-fertilizing as it can burn the roots.
Pruning:
Phalangium elatum requires pruning to ensure it retains a neat and tidy appearance. Cut back the plant's foliage and stems to about 2-3 inches above the ground in late autumn or early spring when growth resumes. Regular pruning will encourage healthy growth and prevent the plant from becoming too leggy.
Propagation of Phalangium elatum (Aiton) Redouté
There are several methods to propagate Phalangium elatum (Aiton) Redouté, which is commonly known as the Tall Spider Flower, including:
Division
Division is the easiest way to propagate this plant. The ideal time to divide is in early spring when the plant starts to grow. Dig up the plant and separate the mature clumps of rhizomes, making sure each clump has a healthy bud. Plant the clumps as soon as possible in a new location or container, and keep them well-watered until they get established.
Seeds
Seeds are another way to propagate Phalangium elatum (Aiton) Redouté, but they require more time and patience. Collect the ripe seedpods from the plant and sow them in a high-quality soil mix, barely covering them with soil. Keep the soil moist and place the container in a warm, bright location. Germination can take up to six weeks.
Cuttings
Phalangium elatum (Aiton) Redouté can be propagated from cuttings, although this method requires a bit more skill. Take a cutting from the stem with several leaves attached, and dip the cut end in rooting hormone. Plant the cutting in a container with a high-quality soil mix, and keep it in a warm, bright location. Keep the soil moist but not soggy. With proper care and attention, the cutting should develop roots within a few weeks.
Whichever propagation method you choose, it is important to provide the right growing conditions to give the new plants the best chance of success.
Disease Management for Phalangium Elatum (Aiton) Redouté
Phalangium Elatum (Aiton) Redouté is an easy-to-grow plant and relatively resistant to diseases. However, there are a few diseases that can affect this plant.
The most common disease that Phalangium Elatum (Aiton) Redouté may encounter is root rot. This is caused by overwatering and poor drainage. To manage root rot, allow the soil to dry out between watering and ensure that the pot has adequate drainage holes.
Another possible disease is leaf spot which is indicated by brown or black spots on the leaves. In order to manage the leaf spot, it is important to remove the affected leaves to prevent the spread of the disease. Also, avoid watering the leaves as this can cause the spread of the disease.
Pest Management for Phalangium Elatum (Aiton) Redouté
