I made many sketches of Campsis grandiflora this summer (July - Oct, Hong Kong has a much longer summer season) as I saw this follower first time in Hong Kong since 1995 when I moved to Hong Kong. Orange ones remind me of the time when I encountered this flower in Japan first time long time ago and Shanghai, also first time in China about 5 years ago. Both times the day was a very hot summer day and day time. Usually orange. But I happened to find bluish purple ones in September in Hong Kong. The best sketch is below.

 

 

 

 

 

 

 

 

 

Bluish purple ones

 

 

After checking I found (actually happened to find) this bluish purple Campsis gradiflora is not Campsis gradiflora but Thunbergia gradiflora and belongs to Acanthacea familiy not to Bigoniaceae family (to which Campsis gradiflora bekongs)
