How to identify flowers in Japan

I've learned a lot about flowers in my time in Japan. However, I still have a lot to learn. The flower in this post for example, I see it every year in Japan, but wasn't sure of the name of it and I was curious. I don't think they have this particular type of orchid in my home country. Certainly not large displays like you can see here in Japan.

If I want to identify a flower, I find the single best way to identify flowers in Japan is to look for a plaque by the flower display with the name of the flower on it. Many of the parks around Japan offer this very useful signage, on trees too. But of the places I've been to see this flower, they don't have a sign. 

Normally, my next step would be to use my trusted little flower book, but I have misplaced it. And not everyone has a flower book in their home. Truthfully, most often I find the best source for flower information is Obaachans! However, there isn't always one on hand! In the end it was an Obaachan that confirmed the name of the flower in this post, but only after I had looked it up on Google Lens. It is called 'Shiran' in Japanese.

Google Lens can be useful, but it is not always accurate. In the case of this flower, the first four results when I used Lens suggested that it was indeed "Shiran", but the following three results were for another unrelated flower. Because Lens gave me a mixture of results, I was not confident they were accurate. Only that an Obaachan confirmed the flower name am I now confident to say that the flower pictured in this post is 'Shiran'!

Do you use Google Lens do identify flowers or other things? Have you any other tips for identifying flowers in Japan?
