The Crepe Myrtle (Lagerstroemia indica) is a widely celebrated ornamental shrub or small tree, recognized for its prolonged summer display of vibrant flowers. This plant is a fixture in many landscapes across warm-temperate regions, where its delicate, ruffled blooms create a beautiful aesthetic. Given its common presence, this information clarifies the safety status of its flowers and other parts.
Edibility and Toxicity Status
Crepe Myrtle flowers and all other plant parts are regarded as non-toxic to humans and common household pets like dogs, cats, and horses. Reputable organizations such as the American Society for the Prevention of Cruelty to Animals (ASPCA) list Lagerstroemia indica as non-poisonous. Accidental ingestion of the flowers, leaves, bark, or seed capsules is unlikely to cause severe or life-threatening poisoning.
A distinction must be made between being non-toxic and being edible. While the Crepe Myrtle does not contain harmful compounds, its parts are not recognized as a food source and possess no nutritional value. Ingesting non-food plant material may still lead to mild symptoms like stomach upset, vomiting, or diarrhea. This minimal reaction is due to the physical irritation of the fibrous plant matter in the digestive system, not the presence of inherent toxins.
Identifying the Crepe Myrtle Plant
Correctly identifying Lagerstroemia indica is important, as misidentification is a common cause of accidental plant poisoning. One of the most distinctive physical characteristics of the mature Crepe Myrtle is its smooth, exfoliating bark, which peels away to reveal mottled patches of underlying wood in shades of gray, brown, and cinnamon.
The leaves are typically dark green and may be arranged opposite, alternately, or in whorls of three along the stem. The flowers grow in large clusters called panicles and feature six delicate, crinkled petals that resemble crepe paper, which gives the plant its common name. These showy flowers range widely in color, from white and pink to deep red and purple.
Traditional and Non-Culinary Uses
The primary function of the Crepe Myrtle in modern landscapes is purely ornamental, valued for its long flowering season and attractive architectural form. Its ability to thrive in warm climates and provide color from mid-summer through fall makes it a highly desirable landscape specimen.
Historically, various parts of the Crepe Myrtle have been utilized in traditional practices, particularly in Asia. Extracts from the leaves, bark, and roots have been used in traditional Chinese and Indian medicine for therapeutic purposes, such as treating inflammation, fevers, and digestive issues. The plant contains compounds that have demonstrated properties like antioxidant and antimicrobial activity in scientific studies. The flowers themselves have also been noted for non-consumptive uses, including the production of perfumes and essential oils.
