I was looking at seeds for sale online here in MX, sort of an ebay type place. They have seeds for several types of black plumeria. I've never heard of a black and I'm wondering if this is photoshop heaven or something?
Here's the site, have a look and tell me what you think?
NONONONO!!!
There is no such thing! In addition, even if there was, Plumeria do not come true from seed.
Thanks for checking! Save your pennies, Jonna!
