Myrtle.

Crepe myrtle is safe— for outdoor gardens with cats.

Yes — crepe myrtle is safe for cats. The ASPCA lists it as non-toxic to cats and dogs.

Crepe myrtle (Lagerstroemia indica) is one of the most popular ornamental trees in warm climates. It's prized for its distinctive crinkled paper-like flowers (the "crepe" name refers to the crepe paper texture), summer-to-autumn blooms, and beautiful exfoliating bark visible year-round.

ASPCA Data

According to the ASPCA:

Toxic Principles: Non-toxic. (Listed under Plants Non-Toxic to Cats — no specific toxicity fields; completely safe.)

Crepe myrtle is completely safe for homes and gardens with cats.

The Spelling Note: Crepe vs Crape

Both "crepe" and "crape" spellings are used interchangeably for this plant. ASPCA uses "Crepe Myrtle" as the canonical name. The plant name comes from the paper-like texture of the flowers (crêpe paper). Both spellings are correct; use whichever you prefer.

What You're Growing

Crepe myrtle is a deciduous tree/shrub featuring:

• Crinkled paper-like flowers — Clusters of pink, red, purple, or white blooms resembling crepe paper
• Extended blooming — Summer through early autumn (months of colour, not just weeks)
• Exfoliating bark — Mottled, colourful bark that peels naturally; winter visual interest
• Deciduous foliage — Orange-red autumn colours before dropping in winter
• Low maintenance — Thrives in hot, sunny locations; drought-tolerant once established
• Multiple sizes — Cultivars range from 10 feet to 25+ feet tall

It's the standout tree for hot-climate gardens.

Growing Crepe Myrtle

Light: Full sun is essential. Crepe myrtle needs 6+ hours of direct sunlight daily. Shade significantly reduces flowering and increases powdery mildew problems.

Water: Water regularly during the growing season, roughly weekly. Once established, crepe myrtle is remarkably drought-tolerant and thrives in hot, dry locations. Reduce watering in winter when the plant is dormant.

Soil: Well-draining soil is important. Crepe myrtle prefers slightly acidic to neutral pH but tolerates a range. Avoid waterlogging; poor drainage causes root rot and disease.

Pruning: Prune in late winter (before growth resumes) to remove dead wood and old seed heads. Remove lower branches to enhance the attractive bark. Avoid "crepe murder" — a harmful practice of cutting the main branches back hard. Let the tree grow naturally with its natural form.

Hardiness: Hardiness varies by cultivar (zone 6–11). Dwarf and southern cultivars are hardier; tender cultivars need zone 8+.

Three-Season Interest

Crepe myrtle earns its place in gardens year-round:

• Spring: New foliage emerges; subtle interest
• Summer & Early Autumn: Months of crinkled paper-like flowers (pink, red, purple, white depending on cultivar)
• Autumn: Orange-red to deep purple foliage before dropping
• Winter: Exfoliating bark in mottled tan, grey, cinnamon, and rust colours — the most visually striking season

Few trees offer such extended visual interest.

Popular Cultivars

• Natchez — White flowers, cinnamon exfoliating bark; one of the most ornamental
• Dynamite — Deep red flowers, compact growth, excellent autumn colour
• Pink — Standard pink form; the most common colour
• Purple — Purple-pink flowers with great autumn foliage

All cultivars are ASPCA safe.

Safe for Cats

Crepe myrtle provides a safe outdoor structure for cats to climb, perch in, and shelter under. All parts of the tree — flowers, foliage, bark, and stems — are non-toxic. Cats can nibble leaves, chew flowers, or brush against branches without risk.

The main consideration is outdoor safety (traffic, predators, weather) — not toxicity.

The Bottom Line

Crepe myrtle is a safe, beautiful, low-maintenance tree for gardens with cats. It offers summer-to-autumn blooms, dramatic autumn colour, and year-round bark interest. Plant it freely in yards where cats roam, knowing they face no toxin risk.

All parts of crepe myrtle are non-toxic — flowers, leaves, bark, and stems.
