Crepe Myrtle vs Lily of the Valley Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Crepe Myrtle
Lagerstroemia indica
Crepe Myrtles are deciduous trees or large shrubs known for their vibrant summer flowers, attractive peeling bark, and colorful fall foliage. They typically grow to heights of 15-25 feet outdoors, though dwarf varieties exist. The flowers come in shades of pink, red, white, and purple, with a crinkled, crepe-like texture. They are primarily grown as ornamental trees in gardens and landscapes for their year-round visual interest. Due to their high light requirements and large size, they are not suitable for indoor growing.
Lily of the Valley
Convallaria majalis
Lily of the Valley is a rhizomatous perennial plant known for its delicate, sweetly scented bell-shaped flowers. It typically grows to about 15-30 cm tall. The plant features two broad, lance-shaped leaves arising from the base, with a raceme of small, nodding white flowers appearing in spring. It spreads via underground rhizomes, forming colonies. While prized for its beauty and fragrance, it's important to remember that all parts of the plant are poisonous. It is primarily an outdoor plant, thriving in woodland conditions.

❓ Frequently Asked Questions — Comparing These Plants
Crepe Myrtle
What are the light requirements for Crepe Myrtle?
Indoor Crepe Myrtles require bright, indirect light to thrive and produce their signature blooms. A south- or west-facing window is ideal, providing several hours of sunlight daily. If natural light is insufficient, supplement with grow lights. Rotate the plant regularly to ensure even light exposure on all sides. Avoid placing the Crepe Myrtle in direct sunlight, which can scorch the leaves. Signs of insufficient light include leggy growth, pale leaves, and a lack of flowering. During the winter months, when light levels are lower, consider providing additional artificial light to support healthy growth.
How do I care for Crepe Myrtle?
To ensure your indoor Crepe Myrtle thrives, provide bright, indirect light, ideally from a south- or west-facing window. Water thoroughly when the top inch of soil feels dry, ensuring proper drainage to prevent root rot. Maintain a moderate humidity level by misting the foliage regularly or using a humidifier. Fertilize during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Prune in late winter or early spring to remove dead or crossing branches and to shape the plant. Repot every two to three years into a slightly larger pot with well-draining potting mix. Monitor for pests such as aphids or spider mites and treat promptly. Maintain stable temperatures between 65-75°F (18-24°C).
How do I propagate Crepe Myrtle?
Crepe Myrtles can be propagated through stem cuttings or air layering. For stem cuttings, take a 4-6 inch cutting from new growth in the 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 until roots develop. For air layering, make a small incision on a stem, apply rooting hormone, and wrap the area with moist sphagnum moss. Cover the moss with plastic wrap and secure it tightly. Once roots develop, cut the stem below the wrapped area and plant it in a pot. Rooting can take several weeks to a few months. Maintain consistent moisture.
Lily of the Valley
What are the light requirements for Lily of the Valley?
Lily of the Valley prefers partial to full shade. While it can tolerate some morning sun, avoid exposing it to harsh afternoon sunlight, which can scorch the leaves. Ideal placement is under the canopy of trees or in a location that receives dappled sunlight throughout the day. Insufficient light can lead to leggy growth and reduced flowering.
How do I care for Lily of the Valley?
Lily of the Valley thrives in partial to full shade, requiring well-draining soil that’s consistently moist but not soggy. Water thoroughly when the top inch of soil feels dry. Fertilize sparingly, using a balanced liquid fertilizer diluted to half strength during the growing season (spring to early summer) to encourage blooming. Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of flowers.
How do I propagate Lily of the Valley?
The most common method for propagating Lily of the Valley is through division. In early spring or fall, carefully dig up an established clump of rhizomes. Gently separate the rhizomes, ensuring that each section has healthy roots and at least one growth bud. Replant the divided rhizomes in well-draining soil, spacing them a few inches apart. Water thoroughly and keep the soil consistently moist until new growth appears.
