As far as naturalists are concerned, the great value of wildflowers is in perpetuating the species, in contributing their very presence to the environment in which they play an integral part, though their particular function may not be well understood, even by botanists where certain habitats have been disturbed by the construction of dams or human habitations or by the cultivation of land farms and forestry, some flowers altogether. It is important, therefore, for amateur naturalists to leave such plants where they are, rather than to pick them or attempt to transplant them to their own gardens. Some wildflowers make lovely garden plants and are easy to grow - - daisies, violets, and buttercups are especially popular and are not all endangered in the wild -- and a pretty wildflower garden can turn any backyard into a showplace. But it is always best to purchase the seeds from a commercial nursery or seed catalog company rather than try to collect flowers from nature. It is not always easy to reproduce growing conditions in which the plant will feel at home, and it would be a shame to risk the loss of a wildflower in this experimental way.
A popular pastime for flower lovers in the days before wildflower was considered a natural treasure was to collect and press them. Some enthusiasts would fill entire albums or create handsome dried collages or arrangements, and even today such object are admired for their beauty. But again, because of the rarity of some flowers and the simple fact that living flowers are always more beautiful than dead ones, collecting them is not recommended. The best ways to bring wildflowers home are through your own photographs or by sketching or painting them on the spot and then displaying your artwork.
