Looking for picture book about a house that was made of plants. The outside world merges surrealy with the inside room (resembles art of Jacek Yerka but it's not him). Book was mostly visual and the color of the art was very green. The story takes place at night. There is an old man with white hair in the house. Likely an older book from the 60s or 70s, or at least has the 60s/70s hippie/spiritual vibe. If you find this with just this info you are unto a god, thank you.
An illustrated ’70s or ’80s children’s book about cartoon-looking bugs living in a city within/on a potted plant. The bugs had houses and shops and children. They wore clothes I think and were quite humanly.
A little boy offers to help his neighbor take care of their houseplants while they’re away, and as each day passes the plants grow and grow, until they’ve filled up the house and are spilling out the windows and doors. I would have seen it as a child in school or at the library in the early 80s, but the book may be from earlier. I believe hardcover, with color illustrations ( I want to say ink and/or colored pencil?) I’ve always been fascinated by plants and this book was my favorite!
