Monkey Flower vs Perilla 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.
Perilla
Perilla frutescens
Perilla frutescens, commonly known as Shiso, is an annual herb typically grown outdoors for its aromatic leaves, which are used in East Asian cuisine. It grows to about 0.5-1 meter tall with a bushy habit. The leaves come in various colors, including green, purple, and variegated forms. While it can be grown indoors, it requires very bright light and consistent care to thrive. People grow it for its culinary uses, ornamental value, and purported medicinal properties. It is considered an invasive species in some regions.

❓ 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.
