Hoya carnosa (Wax Plant) - An evergreen clambering vine to 12-15 ft with thick dark-green pointed 2 to 4 inch long ovate leaves. The fragrant light pink flowers have a darker star-shaped center and are held in rounded dense clusters in late spring to early summer - though sweet, some feel the fragrance too strong. So keep the plant at a distance, the aroma can be enjoyed but walked away from. Plant in cool coastal full sun to part sun or bright light shade. Give regular water but dislikes overly wet conditions. Hardy to 23F, maybe a little less with some overhead protection and recovers well if top growth damaged by cold. Watch for mealy bugs (especially if grown indoors) and golden aphids outdoors. This plant from India, Myanmar and south China is also known as the Porcelain plant because the intricate flowers appear to be made of porcelain or Honey Plant because the flowers drip nectar. The specific epithet comes from the Latin word 'carnis' meaning "fleshy" or "succulent" in reference to the thick leaves of this species.
