Queen's crape myrtles can be easily spotted along the streets of Hong Kong. The deciduous tree grows in tropical and subtropical regions. Compared with crape myrtles, the Queen's crape myrtle has much larger leaves, flowers and crown spread due to ample sunlight.
The Queen's crape myrtle displays huge clusters of white, pink, lavender, or purple flowers in June and July. Its scientific name "Speciosa" refers to its glorious flowers. Widely cultivated in India, the plant is known as "Pride of India" as well.
You can see the purple blossoms in the Botanic Garden at the Horticultural Expo in Beijing.
