Hoya sp. Estrella Waterfalls (IML 1256) was first discovered by David Cumming near Estrella Waterfalls in Palawan, Philippines.  I have not had this plant very long and has flowered essentially from a rooted cutting at less than six months of age.  The blooms are highly scented and will perfume a large area in a hurry.  The leaves vary greatly in size and can get quite large. The care is easy, and seems to tolerate everything that I have thrown at it, from drought, to an over watered condition.  It will handle both above and below normal temperature conditions.  I rate this plant as easy to grow and a must have for any collection!  My plant was sourced from Joni at SRQ Hoyas.
