Hoya sp. DS-70 has been sold for years as Hoya tsangii, burtonii, or other names. It is now proven to be correctly named as Hoya DS-70, which, for those of you that care, would have saved a lot of fuss in the first place!
Hoya DS-70 originates from The Philippines and is another easy tropical vine.
It produces red / purple flowers, but the showpiece are the leaves. They are pubescent, with the dark green leaves framed by darker hues of greens and purple. It is a great foliage plant as well as being well scented.
