What made Hoyas collectible? Hoyas are easy plants to rear and propagate. They bear showy star clustered flowers and most have thick succulent leaves. The hunt became much more interesting when I read from Dale Kloppenburg's literature that there are 60 or more species available all over the archipelago,
From then on a lot more native species became visible. Some native species available in cultivation:
There is the unique Hoya multiflora (which is more shrub like than vining), the shooting star now reclassified under the new genus of Centrostemma.
Hoya meliflua which is a synonym of Hoya luzonica.
The hairy leaved Hoya madulidii named after the famous Dr. Domingo Madulid
The controversial Hoya buotii and its large counterpart Hoya halconensis
The simple Hoya incrassata
The fabulous mottled Hoya imbricata ssp basisubcordata
The bell shaped flowers of Hoya siariae.
...and the cliff dwelling Hoya cumingiana.
