I treasure my Phals for the exact coloring and markings they have naturally. Sometimes, mass production growers dye Phals for the big box stores. You're the first individual I recall who's colored a Phal. WhiteCat8

I think that dyeing tends to shorten the flower life of most things quite a bit. Plants that are sprayed with dye/pigment such as poinsettias definitely tend to abort the flowers/bracts much faster than ones that are not.

A regional chain of "superstores" here in the midwest was promoting their blue phals for Mothers Day. Quite a disgusting abomination IMHO, and most of them were pretty dead looking in the store already, whether it was the dye or just the fact that, like any big box, they abuse the plants, is hard to say.

That blue is really shockingly unnatural, isn't it?
