The genus name is derived from the Greek words “neo” meaning new, and “panax” meaning panacea, which refers to the medicinal properties of some of its species. Neopanax plants are highly valued for their ornamental foliage and adaptability to different growing conditions.

Appearance
Neopanax plants have large, glossy, and leathery leaves that are usually palmately lobed or divided. The leaf size and shape vary depending on the species, but they are typically 4-10 inches long and wide. The foliage colors range from dark green to bronze or variegated, which makes them a popular choice for landscaping and indoor decoration.

Care Guide
Neopanax plants are relatively easy to care for and can thrive in a wide range of growing conditions. Here are some tips for their care:
- Water: Neopanax plants prefer consistently moist but well-drained soil. Water them thoroughly when the top inch of soil feels dry to the touch, but avoid overwatering as it can cause root rot.
- Fertilization: Feed Neopanax plants every 2-3 months with a balanced, water-soluble fertilizer that is specifically formulated for foliage plants.
- Soil: Neopanax plants prefer slightly acidic to neutral soil that is rich in organic matter. Use a well-draining potting mix if growing them in containers.
- Sunlight: Neopanax plants can tolerate a range of light conditions, but they prefer bright, indirect light. Avoid direct sunlight as it can scorch the foliage.
- Hardiness Zones: Neopanax plants are hardy in USDA zones 8-11, but some species can tolerate colder temperatures if protected from frost and wind.
Common Pests & Diseases
Neopanax plants are generally resistant to pests and diseases, but they can still be affected by some common problems. Here are some of them:
- Spider mites: These tiny pests can infest the foliage and cause yellowing, webbing, and leaf drop. Use insecticidal soap or neem oil to control them.
- Mealybugs: These soft-bodied insects can cluster on the foliage and stems and produce a white, waxy substance. Use rubbing alcohol or insecticidal soap to treat them.
- Root rot: This disease is caused by overwatering and poor drainage and can lead to wilting, yellowing, and death of the plant. Improve the soil drainage and reduce watering to prevent it.
Habitat
Neopanax plants are native to various habitats, including forests, scrublands, and wetlands. They grow best in moist, well-drained soils that are rich in organic matter and prefer partial shade to full sun exposure. Some species are adapted to coastal areas and can tolerate salt spray and sandy soils.
