The Scented Calla
This color print shows Mr. Burbank's famous scented Calla. It will be seen that the flower retains the physical characteristics of the ordinary Calla from which it was developed. The scented variety was developed by selective breeding, the original scented specimen being a "sport" that appeared among the almost numberless specimens in Mr. Burbank's garden. By similar selective breeding Mr. Burbank has developed and improved the odors of many other flowers.
