| This shows P. 'Amethyst' on the left and P. kermesina x P. caerulea KC3 on the right. I have many more of these crosses yet to flower. I think it is very clear from this picture and Roland's P. kermesina x P. caerulea crosses, which we think are from different P. caerulea pollen because of foliage differences, that P. 'Amethyst' is indeed an example of P. kermesina x P. caerulea. A comparison:- P. 'Amethyst' 9.5 cm flower diameter. Coronal filaments 4.0 cm diameter. Little pollen. Light pleasant perfume. Smaller flower but a better colour, a less vigorous generally 3 lobed plant. P. kermesina x P. caerulea ref KC3. 11.5 cm flower diameter. Coronal filaments 5.5cm diameter. Speckled androgynophore. More pollen. Identical light pleasant perfume. A bigger flower but a poorer colour so not worth naming, and a very vigorous 5 lobed plant. Hopefully some of the other plants from the same fruit will have the bigger size, a better colour and the vigour! P. 'Justine Lyons' is a very similar flower to this but a bit paler still. What is very interesting genetically is that despite considerable foliage differences all the flowers of this cross to date are the same shape......John Vanderplank has suggested than for some crosses the female gives more to the flower shape & the father more to the foliage. This seems to be a good example of this.
