Wuhan Forest Park is a tree near East Lake with purple, pink and white flowers. Are they cherry blossoms?

Please add photos. If it is in this season, it can't be cherry blossoms. Cherry blossoms bloom in spring.

I think you may be talking about Lagerstroemia speciosa, which is a deciduous shrub or small tree of Lagerstroemia. Its aliases are: itch flower, itch tree, purple flower, purple orchid, mosquito flower, water hyacinth, zinnia and so on. Wei Zihua is beautiful, colorful and has a long flowering period. It is open from June to September, so it has the reputation of "Hundred Days Red" and is deeply loved by people. Distributed in East China, South China and Southwest China.

Ziwei has purple, pink, red, white and other colors. It's warmer this autumn, and you may see flowers in October.
