Episode 28: Let's Talk with Ves Hackney about Hoya lacunosa & Hoya krohniana
THINGS FROM THE EPISODE
You may have heard about the confusion circulating around Hoya lacunosa and Hoya krohniana within the last couple of years. As the community of Hoya hobbyists continue to grow, so does the confusion regarding these two Hoya.

What does the future hold of Hoya krohniana?
Although Hoya krohniana is accepted and recognized as its own species, there is speculation if there is enough taxonomic difference between Hoya lacunosa for it to continue to remain as a species on its own. However, this is only speculation and is still being scientifically researched.
Until a verdict is reached, it is suggested for Hoya to retain their names as received to lessen confusion.
