Could someone explain to me why's my zinnia is color orange, I bought these Zinnia (scarlet-red queen) and now they're color orange Is there something I can do to make it red?
Scarlet red is actually partway between orange and red on the spectrum, so the flowers are probably the color they're supposed to be. I don't think you can change them, unless you crossbreed them until you obtain a true red flower. That would probably take years, though.
My zinnias are starting to color red, I think it's the sun that makes their color darker, I also have another zinnia that is darker in color but they came from the same packet.
