I’ve never been to California, but I remember even as a child being aware of the giant redwood (Sequoia) trees. I seem to recall pictures of some so large that a road had been cut through and motorists could drive through the trees. I did not expect to see examples of the trees in Badenweiler, Germany.
The redwoods, I was told, were planted there in the mid eighteenth century. I don’t know why (English language information didn’t jump out at me), but part of me wondered if they were the first plants of Badenweiler’s botanical garden, which seems to have species from all over the world. Research when I got home told me that a walnut tree was first, but judging from the size of the sequoias they must have been planted shortly afterward.
I am not a tree guy, or a flower guy. I know we have plants in our house. I think they all have green leaves. That is the sum total of my knowledge. Perhaps if we had a Venus flytrap I would be more interested. Carnivorous plants appeal to my science-fiction loving mind.
