BeginnerHoya pubicalyx
A Philippine Hoya with long, fleshy leaves speckled silver. Its flowers are showiest and most fragrant at night, and appear on a Philippine coin.
About
Hoya pubicalyx is an epiphytic climber in the dogbane family (Apocynaceae) from the rainforests of Luzon in the Philippines. The epithet refers to its hairy calyx. It has succulent, lance-shaped leaves, often flecked with silver, and selections such as 'Silver Pink' and the white-and-pink speckled 'Splash' are sold. In strong light the young leaves turn reddish, a protective anthocyanin response, and mature leaves grown in good light take on a silvery-pink tone. The flowers are most noticeable and fragrant at night. They appear on the Philippine five-centavo coin. It is sometimes confused with Hoya carnosa, so check the scientific name on the label. Plants can take around two years to mature and flower. It is widely available from houseplant shops and online retailers in Japan. It likes to be pot-bound and rarely needs repotting.

Growing Tips
Light & Placement
A bright window with indirect light is ideal. Limit direct sun to about two hours in the morning; stronger light scorches the leaves.
Watering
In the growing season water thoroughly after the mix dries; in autumn and winter water less often. Filtered or rain water is preferable to tap water.
Temperature & Overwintering
Frost-tender; keep above 10°C. Aim for 60-70% humidity and avoid direct airflow from heaters or air conditioners.
Soil & Repotting
Use a free-draining mix in a well-drained pot such as terracotta. It likes being pot-bound, so repot only occasionally, and give it a support to climb.
Propagation
Propagate by stem cuttings.
Pests & Cautions
Watch for mealybugs, aphids and whiteflies. Do not remove old flower spurs, which bloom again in later years. North Carolina State Extension lists this species as non-toxic to dogs and cats.
