A bit off topic, but there's a game called Strange Horticulture that I'm playing and loving it. It's a phantasy investigation game. The plants are not real and they have magic properties, but still, I think whoever loves plants will have a lot of fun with it.
Oh yeah that game rocks. I'd recommend it to anyone with kids (especially those with an interest in plants) around 5-9 range. https://www.strangehorticulture.com/
