Elder vs Persian Violet Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Elder
Sambucus nigra
Sambucus nigra, commonly known as Elder or Elderberry, is a deciduous shrub or small tree typically growing to 5-10 meters tall. It features pinnately compound leaves and produces large, flat-topped clusters of creamy-white flowers in late spring to early summer, followed by clusters of small, dark purple to black berries in late summer. While primarily an outdoor plant, it is sometimes grown in large containers, though it requires significant space and is unlikely to thrive indoors long-term. People grow it for its ornamental value, edible berries (when cooked), and medicinal properties.
Persian Violet
Exacum affine
Exacum affine, commonly known as Persian Violet, is a small, bushy, flowering plant typically grown as an annual or biennial. It features compact growth, reaching about 6-8 inches in height. The plant is characterized by its small, oval-shaped, glossy green leaves and a profusion of fragrant, star-shaped flowers, usually violet-blue, but also available in white, pink, and lavender. While often sold as an indoor plant, it thrives best in bright, indirect light and can be challenging to maintain indoors long-term due to its high light and humidity requirements. People grow it for its charming, abundant blooms and sweet fragrance.

❓ Frequently Asked Questions — Comparing These Plants
Elder
What are the light requirements for Elder?
Elder trees thrive in bright, indirect light. While they can tolerate some direct morning sun, prolonged exposure to intense afternoon sun can scorch their delicate leaves. Place your indoor Elder near an east- or west-facing window where it will receive plenty of filtered sunlight. If you notice the leaves becoming pale or yellowing, it may be a sign that the plant is receiving too much direct light. Conversely, if the plant becomes leggy or the leaves lose their vibrancy, it may need more light. Supplement with a grow light if natural light is insufficient, especially during the darker winter months. Monitor the plant’s growth and adjust its placement as needed to ensure optimal light exposure.
How do I care for Elder?
Provide your indoor Elder tree with bright, indirect light. Too much direct sun can scorch the leaves. Water thoroughly when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Use a well-draining potting mix formulated for trees or shrubs. Maintain a stable environment, avoiding sudden temperature fluctuations and drafts. Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Prune regularly to maintain shape and size, removing any dead or damaged branches. Repot every 1-2 years, or when the plant becomes root-bound, into a slightly larger pot. Check regularly for pests and treat promptly. Provide adequate humidity, especially during dry winter months, by misting the plant or using a humidifier. Ensure the pot has drainage holes. Rotate the plant periodically to ensure even growth.
How do I propagate Elder?
Elder can be propagated through stem cuttings or air layering. For stem cuttings, take a 4-6 inch cutting from a healthy stem in spring or summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in moist, well-draining potting mix. Cover with a plastic bag to create a humid environment and keep in bright, indirect light. Roots should develop in a few weeks. For air layering, wound a section of stem and wrap it with moist sphagnum moss. Cover the moss with plastic wrap and secure it with tape. Keep the moss moist. Once roots have formed, cut the stem below the roots and plant in a pot. Ensure the pot is appropriately sized.
Persian Violet
What are the light requirements for Persian Violet?
Persian Violets thrive in bright, indirect light. An east-facing window is ideal, as it provides gentle morning sun without the harsh intensity of midday or afternoon sun. A north-facing window can also work, but the plant may not bloom as prolifically. Avoid direct sunlight, especially during the hottest part of the day, as it can scorch the leaves and damage the delicate blooms.
How do I care for Persian Violet?
Persian Violets thrive in bright, indirect light; avoid direct sunlight, which can scorch their leaves. Water thoroughly when the top inch of soil feels dry, allowing excess water to drain away. Overwatering can lead to root rot. Maintain moderate humidity, especially during dry months, by misting the plant or placing it on a pebble tray filled with water.
How do I propagate Persian Violet?
Persian Violets can be propagated through stem cuttings or division. For stem cuttings, take a 2-3 inch cutting from a healthy stem, remove the lower leaves, and place it in water or moist potting mix. Keep the cutting in a warm, humid environment until roots develop.
