Lemon Cypress vs Monkey Flower Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Lemon Cypress
Cupressus macrocarpa 'Goldcrest Wilma'
Lemon Cypress 'Goldcrest Wilma' is a dwarf conifer prized for its vibrant golden-yellow foliage and distinct lemon scent when the needles are crushed. It has an upright, columnar growth habit, making it a popular choice for topiary, containers, and small gardens. While it can be grown indoors, it's primarily an outdoor plant and requires specific conditions to thrive inside. People grow it for its ornamental value, fragrance, and festive appearance, especially during the holidays.
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.

❓ Frequently Asked Questions — Comparing These Plants
Lemon Cypress
What are the light requirements for Lemon Cypress?
Lemon Cypress requires bright, indirect light to thrive indoors. Insufficient light can cause the foliage to become pale and leggy. Place your Lemon Cypress near a sunny east- or west-facing window, where it can receive several hours of bright light each day. Avoid direct sunlight, which can scorch the delicate needles. If natural light is limited, supplement with a grow light. Rotate the plant regularly to ensure even light exposure on all sides. A south-facing window can work if filtered with a sheer curtain.
How do I care for Lemon Cypress?
Lemon Cypress thrives in bright, indirect light, requiring at least 6 hours daily. Water thoroughly when the top inch of soil feels dry, ensuring proper drainage to prevent root rot. Maintain moderate humidity levels, especially during dry indoor conditions, by misting regularly or using a humidifier. Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer. Repot every 1-2 years in spring, using a well-draining potting mix. Prune lightly to maintain shape and remove any dead or yellowing foliage. Ensure proper air circulation to prevent fungal diseases. Rotate the plant regularly for even growth. Maintain a stable temperature between 60-75°F (15-24°C).
How do I propagate Lemon Cypress?
Lemon Cypress can be propagated through stem cuttings or air layering. For stem cuttings, take a 4-6 inch cutting from new growth in spring. 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. Rooting may take several weeks. For air layering, make a shallow cut on a 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 develop, cut the stem below the rooted area and plant it in a pot. Rooting hormone can improve success rates for both methods. Maintaining consistent humidity is key.
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.
