Common name:  Wax Plant


Special Notes: Hoyas most often grow as epiphytes in tropical forests where they climb into or hang from tree branches. Blooms often form clusters, or umbels, of many flowers and most Hoya flowers are fragrant. The ‘Reva’ was cultivated by botanist Robert Dale Kloppenburg, a UC Berkeley alum.  He named this cultivar after his mother. During warmer months feed plants every two or three weeks lightly with a fertilizer. Easy to grow from cuttings.
