I received Hoya sp. Surigao Del Sur late last summer as a freebie in a trade with a nice woman from Maine. The Hoya that I traded for was called H. Scarlett O’Hoya with a name like that how could I refuse. So far that cultivar has not done particularly well for me, but the one that came as an extra has behaved spectacularly. The leaf coloration alone is reason enough to grow this one!
