'Harison's Yellow' showing an unusual flush of red on the fronts of the petals (6/29/2003). The color isn't quite right -- the yellow was more intense. The sudden appearance of this red pigment following a heatwave suggests that the "genes for red" of R. foetida bicolor are inherent in 'Persian Yellow' and 'Harison's Yellow', but are normally suppressed.
