Here is why I think Hoya multiflora is superior as a houseplant to Hoya lockii: Hoya multiflora has nicer foliage – the leaves are broader and just nicer. I think the flowers are more interesting with better coloration. The biggest reason that I like Hoya multiflora more than Hoya lockii is that it is just a much more vigorous and easier to grow plant, so three cheers for Hoya multiflora!
