Lagerstroemia speciosa
Lagerstroemia speciosa, also known as Giant Crape-myrtle, Queen's Crape-myrtle, or Pride of India, is a large deciduous tree with showy flowers and attractive bark. It is native to tropical southern Asia. Its vibrant pink to purple flowers bloom in the summer, creating a stunning display. The tree also offers ornamental value with its peeling bark, revealing a smooth, mottled surface. It is known for its relatively fast growth and tolerance of various soil conditions.
CategoryDetails
Plant TypePerennial plant
Medicinal UsageMedicinal Usage
Estimated Plant Lifespan50 years lifespan
Sun Requirements6+ hours direct sunlight (Full Sun)
Pollination

Method: Animal

Notes: Bees and other insects are the primary pollinators.

Watering Requirements

Method: Top water

Frequency: Water deeply when the top inch of soil feels dry to the touch, especially during hot, dry periods. Reduce watering in cooler months.

Notes: Lagerstroemia speciosa is relatively drought-tolerant once established, but regular watering promotes optimal growth and flowering.

Humidity Requirements

Level: Moderate

Cleaning RequirementsPrune in late winter or early spring to remove dead, damaged, or crossing branches. Avoid excessive pruning, as it can reduce flowering. Fertilize in spring with a balanced fertilizer formulated for flowering trees.
Temperature Range

Min: 15°C

Max: 38°C

Ixora coccinea
Jungle flame
Ixora coccinea
Ixora thrives in similar warm, humid conditions as Lagerstroemia speciosa and their contrasting flower colors (red/orange vs. pink/purple) create a visually appealing landscape.
Hibiscus rosa-sinensis
Chinese hibiscus
Hibiscus rosa-sinensis
Hibiscus shares similar soil and sunlight requirements and provides continuous flowering, complementing the seasonal blooms of Lagerstroemia speciosa. Also, its shrubby habit can offer a contrasting form.
Eucalyptus globulus
Tasmanian blue gum
Eucalyptus globulus

Eucalyptus trees are fast-growing and can quickly outcompete Lagerstroemia speciosa for resources like sunlight and water, especially when young.

Ficus benjamina
Weeping fig
Ficus benjamina

Ficus benjamina is a large tree with an aggressive root system that could compete for nutrients and water, particularly in confined spaces.

Aphids

Aphids are small, sap-sucking insects that can cluster on new growth. Infestation can lead to distorted leaves, stunted growth, and honeydew production, attracting ants and promoting sooty mold.

Crape Myrtle Bark Scale (CMBS)

These small, white to gray, felt-like scales attach themselves to the bark of Lagerstroemia speciosa. Symptoms include black sooty mold growing on the honeydew excreted by the scales and reduced flowering.

Powdery Mildew

A fungal disease that appears as a white or grayish powdery coating on leaves and stems, especially in humid conditions. It can weaken the plant and reduce flowering.

Steps:

    • Take softwood or semi-hardwood cuttings (6-8 inches long) from healthy, disease-free stems, ideally in late spring or early summer.
    • Remove the lower leaves from the cutting, leaving only a few leaves at the top.
    • Dip the cut end in rooting hormone.
    • Plant the cutting in a well-draining potting mix (e.g., a mix of perlite and peat moss).
    • Keep the soil moist and provide high humidity by covering the cutting with a plastic bag or humidity dome.
    • Place the cutting in a warm, bright location, but avoid direct sunlight.
    • Roots should develop in a few weeks. Once rooted, transplant the cutting into a larger pot or directly into the ground.

Neem Oil

Effective against aphids and other sap-sucking insects, as well as powdery mildew.

Insecticidal Soap

Controls aphids and other soft-bodied pests through direct contact.

Bacillus thuringiensis (Bt)

Controls certain caterpillar pests that may occasionally feed on Lagerstroemia speciosa leaves.

Compost Tea

Improves soil health and provides nutrients, promoting vigorous growth and increased resistance to pests and diseases.
