Best crepe myrtle cultivars

*Lagerstroemia* is a genus of trees and shrubs from Asia and Australia. Per Clemson HGIC, the species most commonly grown in North American landscapes is *Lagerstroemia indica*, the crepe myrtle (also spelled crape myrtle), along with its hybrids with *L. fauriei*. It is the dominant.

Lagerstroemia is a genus of trees and shrubs from Asia and Australia. Per Clemson HGIC, the species most commonly grown in North American landscapes is Lagerstroemia indica, the crepe myrtle (also spelled crape myrtle), along with its hybrids with L. fauriei. It is the dominant summer-flowering tree across the southeastern United States, producing panicles of ruffled flowers in white, pink, lavender, or red from June through September.

I don't grow crepe myrtle in Melville, Long Island — it is marginal in zone 7a, dies back in most winters, and the deer browse the new growth. The guidance below is sourced from Clemson HGIC, NC State Extension, and USDA/USNA cultivar records.

The Indian Tribe series (US National Arboretum)

The most important cultivar development in crepe myrtle history was the USNA breeding program that hybridized L. indica with L. fauriei (Japanese crepe myrtle) to introduce powdery mildew resistance, which is the primary disease of L. indica in humid climates. Per USDA Agricultural Research Service, the hybrid offspring were named for Native American tribes and introduced starting in the 1960s through the 1990s.

Large tree cultivars (20—30 ft)

Stop fungal disease early

Neem oil suppresses powdery mildew, black spot, and rust when sprayed at first sign. Cheaper than copper-based fungicides and safe on veg. Read our full pick.

Medium tree cultivars (10—20 ft)

Compact and dwarf selections (under 8 ft)

Compact crepe myrtles derived from further L. indica breeding, often without L. fauriei parentage — which means mildew resistance is more variable.
