Pink Japanese Stewartia (Stewartia Pseudocamellia) ピンクの夏椿（ナツツバキ）

First I was surprised to find these camellia like flowers on the street I walk down every morning and then a common straight swift landing on one of the flowers. These flowers are Japanese stewartia (Stewartia pseudocamellia). As part of its scientific name "pseudocamellia" suggests, the Japanese stewartia is related to camellias and therefore called natsu tsubaki in Japan, which means summer camellia. The camellia is evergreen while the Japanese stewartia is deciduous.

I've been taking a walk every morning for the last three years and photographing the flowers I see while walking. And I noticed for the first time that there's a Korean or Japanese stewartia tree (Stewartia pseudocamellia) along the street I walk everyday😅. 

The stewartia resembles camellia sasanqua/japonica, which blooms from winter to early spring, so I wondered at first why camellia was in bloom at this time of the year. But Stewartia is related to Camellia (i.e., both being in the Theaceae family) and Korean/Japanese stewartia blooms in early summer as suggested by its Japanese name "summer camellia."

These are fruits of Stewartia pseudocamellia, also known as Japanese stewartia. The tree is called "summer camellia" because it produces flowers which look like camellia in summer. You can see the resemblance in its English scientific name "Stewartia pseudocamellia," too.

They are the fruit of the stewartia pseudocamellia or Korean stewartia or Japanese stewartia I saw at Tennōji temple in Ueno, Tokyo. It took me two hours to identify the tree for a reason you can see in the third photo...
