Taxonomic Information

Appearance

Oberonia plants are small and delicate, with thin and wiry stems that can grow up to 30cm in length. The leaves are strap-shaped and grow in a rosette pattern. They are usually green, but some species have yellow, pink, or purple foliage. The flowers are small and grow in clusters along the stem. They come in a variety of colors, including white, pink, purple, and yellow.

Care Guide

Oberonia plants are relatively easy to care for, but they require specific conditions to thrive. Here are some care tips:

Water

Oberonia plants prefer to be kept moist but not wet. Water them regularly, but allow the soil to dry out slightly between waterings. Avoid getting water on the leaves and flowers, as this can cause damage or rot.

Fertilization

Fertilize Oberonia plants every two weeks during the growing season using a balanced orchid fertilizer. Reduce or stop fertilizing during the winter months.

Soil

Oberonia plants need a well-draining soil mix that allows air to circulate around the roots. Use a mixture of orchid bark, sphagnum moss, and perlite or vermiculite.

Sunlight

Oberonia plants prefer bright, indirect light. They can tolerate some direct sun in the morning or late afternoon, but too much direct sunlight can damage or burn the leaves.

Hardiness Zones

Oberonia plants are tropical plants and thrive in warm, humid conditions. They are not cold-hardy and should be kept in temperatures above 60°F (15°C).

Common Pests & Diseases

Oberonia plants can be susceptible to pests such as spider mites, mealybugs, and scale insects. These can be treated with insecticidal soap or neem oil. The plant may also be prone to fungal or bacterial infections, which can be prevented by maintaining good air circulation and avoiding overwatering.

Habitat

Oberonia plants are native to the Asian continent, where they grow in humid, tropical forests. They are epiphytic plants that grow on rocks, trees, and other structures. They can be found at elevations ranging from sea level to over 2000 meters.
