Burbank, Luther, 1849-1926 / Luther Burbank: his methods and discoveries and their practical application
Experimenting with the responsive dahlia -- an infinity of variation which has only been tapped, pp. -
ON THE DAHLIA undoubtedly been felt in the rather striking results attained in working with a race of flowers that, despite its comparatively recent advent in the hor- ticultural garden, is already highly specialized. That further improvements of striking charac- ter will be attained can scarcely be doubted by any one who takes into account the fact that the dahlia is a parvenu among the admitted aristo- crats of the flower garden. It is impossible that the hereditary resources of any plant should have been exhausted within the comparatively brief period of time that has elapsed since this extra- ordinarily responsive and adaptable flower was first brought from the wilds. -Brought from sub-tropical Mexico to the relatively cold climate of England, the dahlia soon showed the effects of the altered climatic condition. The tendency to vary was accentu- ated and presently there was a new race of dahlias, so utterly divergent from the parent form as to be almost unrecognizable.
