Hoya halophylla — rare mangrove hoya with thick yellowish-green leaves, cream-white star flowers with reddish corona. Salt-tolerant.
Pot diameter: (no pot)
Hoya halophylla is a rare and fascinating species, one of the few hoyas adapted to mangrove habitat and saltwater shores. The species name (Greek "halos" = salt + "phyllon" = leaf) reflects its unusual habitat: Indonesia and Philippines, in mangrove forests where leaves are sometimes splashed by seawater.
Leaves are thick, fleshy, oval, yellowish-green, adapted to store water and tolerate salinity. Flowers appear in small umbels with cream-white star flowers with reddish corona. A rare piece in hoya collections.
Mangrove forests and tropical shores of Indonesia and Philippines, where it tolerates air salinity and very high humidity conditions.
Bright indirect to direct morning light, high humidity (70-90%), temperatures 22-30°C. Airy substrate that retains moisture: orchid bark + perlite + sphagnum + coconut fibers. Moderate watering, tolerates short drought periods.
Flowers at maturity, umbels of 8-12 cream-white star flowers with reddish corona, sweet evening fragrance.
Not toxic to cats, dogs or children. Safe Apocynaceae. Milky sap may irritate skin.
Prefers bright indirect light and very well-draining substrate. Water less frequently than other Hoyas as the succulent leaves store water. Ideal temperature: 18-28°C.
The thick succulent leaves are an adaptation to environments with fluctuating humidity. They store water, allowing the plant to survive dry periods.
No, it is a non-toxic plant, safe for pets and children.
Hoya halophylla blooms at maturity under adequate light conditions. Flowers are waxy, fragrant, grouped in umbels.
A very well-draining mix: bark, perlite, charcoal, and a little sphagnum. Avoid substrates that retain too much moisture.
From Greek, 'halos' = salt and 'phyllon' = leaf. Refers to the species' habitat in mangrove forests where leaves tolerate exposure to saltwater and salty air.
Hoya halophylla is native to tropical mangrove forests of Indonesia and Philippines, where it grows in coastal areas with very high humidity and occasional salinity.
Yes, better than many hoyas. It tolerates direct morning sun (or strong filtered light) thanks to adaptation to open mangrove habitat. Avoid intense midday sun.
No, Hoya halophylla is not toxic to cats, dogs or children. The Apocynaceae family is safe, but the milky sap may irritate sensitive skin.
No, although it tolerates salinity, use normal fresh water. It tolerates mineral salts from tap water, but distilled or rainwater is ideal for optimal growth.
