My Hoya parasitica was obtained from a Thai vendor who very kindly threw it in as an extra on an order in 2010.  I don’t know much about the plant other than there are a number of clones of the species that are broken down into three distinct groupings.  I am unsure which group my plant falls into.  It makes a handsome plant that blooms and grows quite easily with ordinary care.  The leaves have pronounced veining with plenty of silver splotching.  The blooms have a powerful scent and last around five to seven days before dropping.  This Hoya makes a wonderful beginner plant for those new to Hoyas.   I can heartily recommend this plant to everyone.

Update December 2022: Hoya parasitica is now considered to be a synonym for Hoya verticillata.
