Lagerstroemia, commonly known as crepe myrtle, is a deciduous tree or shrub appreciated for its vibrant flowers, attractive bark, and autumn colour. Although not native to Australia, it is well adapted to many Australian conditions, with modern cultivars offering drought hardiness, compact growth, and impressive ornamental qualities. Crepe myrtles are used in streetscapes, courtyards, and feature plantings, and can also contribute to urban biodiversity.
- Lagerstroemia spp ‘CM02’ PBR Trade Name Canopy™ — vibrant pink flowers, burgundy foliage
- Lagerstroemia spp ‘CM01’ PBR Trade Name Grande Red™ — compact, red-flowered, drought-hardy tree
- Lagerstroemia spp ‘CM03’ PBR Trade Name Pinky Pink™ — compact, pink-flowered, drought-hardy shrub
Nectarivorous Birds
Unknown — Probably Beneficial
While insects are attracted to the flowers, there is limited evidence of nectar-feeding birds making significant use of crepe myrtles in Australian urban landscapes. However, birds do feed upon the flowers in their natural range in Asia so it is reasonable to assume they are beneficial.
Fruit Eating Birds
No — Not a Food Source
The dry seed capsules of crepe myrtle are not fleshy or appealing to frugivorous birds. Add Caprobrotus glaucescens orRhagodia spinescens for this resource.
Seed Eating Birds
Unknown — Requires Verification
There is no documentation suggesting that granivorous birds make use of crepe myrtle seeds in Australia. Opt for native grasses for this resource.
Insectivorous Birds
Yes — Support via Insects
By attracting pollinating insects, crepe myrtles can create foraging opportunities for insectivorous birds.
Pollen Feeding Insects
Yes — Documented Use
The abundant flowers are visited by bees (including honeybees and likely native bees) and beetles that collect pollen during the flowering season.
Nectar Feeding Insects
Yes — Documented Use
Butterflies, bees, hoverflies, and other insects utilise the nectar of crepe myrtle flowers, particularly valuable during the summer heat when few other trees are flowering.
Buzz Pollinated Flowers
No — Not Buzz-Pollinated
Lagerstroemia flowers do not require buzz pollination and can be accessed by generalist pollinators.
Habitat for Desirable Insect Larvae
Yes — Provides Shelter
While not a known host plant for specific Lepidoptera, the canopy and bark offers shelter to predatory insects, spiders, and other beneficial invertebrates.
Final Thoughts for Specifiers
Crepe myrtles offer reliable ornamental impact alongside moderate support for urban pollinators and insectivorous birds. Cultivars such as those mentioned above deliver drought resilience, compact form, and seasonal colour, making them suitable for streetscapes and low-maintenance designs.
