They certainly liked flowers.  Every home seemed to have window boxes or small planters around it.  He was fairly sure he saw a pale white pony with a maroon mane eating out of one, but it was quite hard to tell without his glasses.  Based on his observations so far, most ponies manipulated a lot of things by mouth, which really made sense given their lack of fingers.  Weeding a flowerbox and grazing might not actually be dissimilar activities, now that he thought about it. And Lyra had given him a sandwich with flowers on it yesterday when they’d shared lunch in his camp.  Her lunch at their first meeting had had a flower sandwich, too.
