The Call of the Wildflower is a book that describes various many species of British wildflowers and it has the following passage: THE call of the wild, where the love of flowers is concerned, has an attraction which is not the less powerful because it is difficult to explain. The charm of the garden may be strong, but it is not so strong as that which draws us to seek for wildflowers in their native haunts, whether of shore or water-meadow, field or wood, moorland or mountain. A garden is but a zoo (with the cruelty omitted); and just as the true natural history is that which sends us to study animals in the wilds, not to coop them in cages, so the true botany must bring man to the flower, not the flower to man.
