One example: in many genera the alba form is weak and delicate, while in Paphs. the album form, such as the Maudiae group, is quite vigorous. I am not sure how it affects houseplants, but in the wild, plants in the tropics sport large flamboyant blossoms, but as you go further north, flowers become smaller & paler. Here in the Northeast, there is not enough light to support many outdoor perennials and trees with dark colors. If they succeed in gene splicing very dark or spectacular colors into large cattleyas, for instance, they may only bloom well in Florida. Iris
