Pinaropappus roseus

Thanks to David Tarrant are once again in order for today's photograph from Mexico. Appreciated as always, David.

Despite a specific epithet (roseus) that translates to “pink”, the common name often used in the USA for this species is white rocklettuce. Pink dandelion is also sometimes used, as is white dandelion. Curiously, it seems the plants growing in the northern part of its range (south-central USA) tend to have little pink colouration (e.g., these photographs from the Lady Bird Johnson Wildflower Center), while those growing in the southern part of its range (central Mexico) are quite pink (e.g., today's photograph and this other photograph from Mexico).

Are the variations in color due to change in soil conditions or other environmental conditions?

I'm afraid I don't know - I'm drawing an inference from the geolocated photographs I've seen online, so it may not even be a valid conclusion.

Could it be perhaps that there seem to be two varieties, foliosus and roseus? I cant seem to be able to find pictures of either, however.
