Here's a pic of one of my P. goeldii hybrids that threw blooms this Spring with nearly black spathes and sharply contrasting white spadices. The parentage is (coral gables dwarf x P. bipinnatifidum type) x P. goeldii - the spathe color could only have come from the P. bipinnatifidum used in the first cross, meaning that plant was a hybrid, not a species.
The unopened bloom shown has since opened and I've crossed it with pollen from my hybrid, P. "Waverly", shown in bloom in picture below. (Edited to note that the pollinated "black" bloom has fallen off so evidently this cross failed).
Colored blooms are not unheard of in Meconostigma Philos; one species I need for my work is P. eichleri, which has brilliant red blooms. I have an eichleri x stenolobum hybrid with the red blooms, but so far have not gotten a successful cross on it. The plant is throwing blooms this Spring, so will try again!
