Seasonal Order of Colour in Flowers


I AM very much obliged to Mr. Buchan for his elaborate paper in NATURE, vol. xiii. p. 249, on the Flowering of Spring Plants (see my query, NATURE, vol. xiii. p. 129). Although agreeing with Mr. Pryor that the blue is anticipated by various other colours, yet I think that the method of inquiry by averages is the only basis we can go upon; and that is the plan I have adopted for some time. I have now a carefully-assorted collection of hyacinths, and I see that the blue and white are coming out nearly together, the red showing as yet no colour whatever. What would be the action of light upon blue or red flowers, if the blue or red ray was carefully excluded, if this could be done? Would the flower thrive, and if so, would its colour be much altered?
