Fishtail Palm vs Oleaster Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Fishtail Palm
Caryota mitis
Caryota mitis, the Fishtail Palm, is a clustering palm known for its unique, bipinnate leaves that resemble the tail of a fish. It is a multi-stemmed palm, meaning it grows in clumps from the base. While it can reach considerable heights outdoors, it remains smaller when grown in containers. People grow it for its tropical appearance and interesting foliage. It is primarily an outdoor plant but can be grown indoors with proper care and sufficient light.
Oleaster
Elaeagnus pungens
Elaeagnus pungens, commonly known as Thorny Olive or Silverthorn, is a dense, evergreen shrub or small tree. It is characterized by its silvery-green foliage, often speckled with brown. The leaves are leathery and alternate, with a wavy margin. Small, fragrant, creamy-white flowers appear in autumn, followed by reddish-brown, olive-like fruits in spring. It is primarily grown as an ornamental plant for its attractive foliage and tolerance of difficult conditions. It is not typically grown indoors due to its size and high light requirements. It can become invasive in some regions.

- Maintain consistent soil moisture, but avoid overwatering.
- Increase humidity by misting regularly or using a humidifier.
- Fertilize regularly during the growing season to promote healthy growth.
- Monitor for pests and diseases and treat promptly.
Oleaster Care Tips
Elaeagnus pungens is an outdoor shrub or small tree that is not suited for indoor growing due to its size and high light requirements. It needs full sun and well-draining soil. It can become invasive in some areas. Requires regular pruning to maintain shape.
- Plant in well-draining soil in a sunny location.
- Water deeply but infrequently, allowing the soil to dry out between waterings.

❓ Frequently Asked Questions — Comparing These Plants
Fishtail Palm
What are the light requirements for Fishtail Palm?
Fishtail Palms prefer bright, indirect light. Too much direct sunlight can cause leaf scorch, resulting in brown spots and crispy edges. An east-facing window is often ideal, providing gentle morning light. A north-facing window can also work if the light is sufficiently bright. If placing the palm near a south or west-facing window, use sheer curtains to filter the light. Rotate the plant regularly to ensure even growth on all sides. Insufficient light can lead to leggy growth and pale leaves. If you notice these signs, move the plant to a brighter location. Artificial grow lights can supplement natural light, especially during the darker winter months.
How do I care for Fishtail Palm?
Fishtail Palms thrive in bright, indirect light. Avoid direct sunlight, which can scorch the leaves. Water thoroughly when the top inch of soil feels dry, ensuring good drainage. Maintain high humidity levels by misting regularly or using a humidifier. The ideal temperature range is between 65-80°F (18-27°C). Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Reduce watering and fertilization during the dormant season (fall and winter). Repot every 2-3 years, or when the plant becomes root-bound, using a well-draining potting mix. Prune away any dead or yellowing fronds to maintain the plant’s appearance and health. Monitor for pests such as spider mites and mealybugs, and treat promptly if necessary. Ensure adequate air circulation to prevent fungal diseases.
How do I propagate Fishtail Palm?
Fishtail Palms can be propagated from seeds or by division of clumping types. For seed propagation, soak the seeds in warm water for 24 hours before planting them in a well-draining potting mix. Keep the soil consistently moist and provide warmth. Germination can take several weeks or months. For division, carefully separate the clumps of the plant when repotting, ensuring each division has healthy roots. Plant each division in its own pot with well-draining potting mix. Water thoroughly and provide bright, indirect light. Maintain high humidity levels. Propagation from seeds is a slow process. Division is best done in spring or early summer. New growth will indicate successful propagation.
Oleaster
What are the light requirements for Oleaster?
Oleaster thrives in bright, indirect light. Insufficient light can lead to leggy growth and dull foliage. Ideally, place your Oleaster near an east- or west-facing window where it can receive several hours of filtered sunlight each day. Avoid direct sunlight, which can scorch the leaves. Rotate the plant regularly to ensure even light exposure on all sides. If natural light is limited, supplement with a grow light. Position the grow light 12-18 inches above the plant for 12-14 hours per day. Observe the plant’s foliage: pale or stretched leaves indicate a need for more light.
How do I care for Oleaster?
Oleaster plants thrive indoors with bright, indirect light. Water thoroughly when the top inch of soil feels dry, ensuring proper drainage to prevent root rot. Maintain moderate humidity levels, especially during dry winter months, by misting the foliage or using a humidifier. Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Prune regularly to maintain shape and remove any dead or damaged branches. Repot every 2-3 years into a slightly larger pot with well-draining potting mix. Maintain a stable temperature between 60-75°F (15-24°C). Monitor for pests such as spider mites and treat promptly with insecticidal soap. Ensure good air circulation to prevent fungal diseases.
How do I propagate Oleaster?
Oleaster can be propagated through stem cuttings or air layering. For stem cuttings, take a 4-6 inch cutting from new growth in spring or summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in a well-draining potting mix and keep it moist in a humid environment. Roots should develop in 4-6 weeks. For air layering, make a small incision on a stem and wrap it with moist sphagnum moss. Cover the moss with plastic wrap and secure it with tape. Roots should develop within a few months. Once roots are visible, cut the stem below the rooted area and pot it in a well-draining potting mix.
