Thoughts of 30 Nov.

I’ve bought this secondhand book which printed in 1975.

The book about edible wild plants. I’ve found the text that:

Tiger lilies are decreasing, so please leave 2-3 leaves when collecting flowers, and when collecting bulbs, please return 1-2 pieces to the soil.

I also have a book about herb and edible wild plants which published in 2020 and Highly rated on Amazon Japan. The book said about Tiger lilies:

Do not dig up wild bulbs, and buy bulbs produced for food as wild species are declining due to overharvesting.

It’s painful to see the reality. 
No respect made this result.
