Monkey Flower vs Persian Violet Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Monkey Flower
Mimulus aurantiacus
Mimulus aurantiacus, commonly known as Sticky Monkey-flower, is a perennial shrub native to the California chaparral. It typically grows to 1-5 feet tall and wide, featuring narrow, sticky leaves. The plant is named for its bright orange, tubular flowers that resemble a monkey's face. It thrives in dry, sunny conditions and is well-adapted to drought. While primarily an outdoor plant, it is grown for its vibrant flowers and ability to attract pollinators like hummingbirds and butterflies. Indoor cultivation is challenging due to its high light requirements and need for well-draining soil.
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
Monkey Flower
What are the light requirements for Monkey Flower?
Monkey Flowers require bright, indirect light for optimal growth and blooming. Direct sunlight can scorch the leaves, especially during the hottest part of the day. An east-facing window is ideal, providing gentle morning sun. A west-facing window can work, but be sure to provide shade during the afternoon. If growing indoors, supplement with grow lights if natural light is insufficient. Insufficient light can lead to leggy growth and reduced flowering. Rotate the plant regularly to ensure even light exposure on all sides. If the leaves start to look pale or yellowish, it may be a sign of too much light.
How do I care for Monkey Flower?
Monkey Flowers thrive in bright, indirect light. Water thoroughly when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Fertilize regularly during the blooming season with a balanced liquid fertilizer, diluted to half strength, every two to four weeks. Maintain moderate humidity levels, around 40-60%. Prune spent flowers to encourage new blooms. Repot in spring if the plant becomes root-bound, using a well-draining potting mix. Monitor for pests like aphids and spider mites, and treat promptly with insecticidal soap. Provide good air circulation to prevent fungal diseases. In winter, reduce watering and hold off on fertilizer.
How do I propagate Monkey Flower?
Monkey Flowers can be propagated through division, stem cuttings, and seed.
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.
