I received Hoya javanica ‘Milky Way’ as a starter plant from SRQ Hoyas in the summer on 2012. It was a nice plant and grew rapidly, but was plagued by a Spider Mite infestation. I finally got sick of trying to kill the mites; took a cutting and threw the plant out. I then submerged the cutting under water for one week hoping to drown the little beggars. It proved useless within a few weeks the mites were back as severe as before. I have used a number of products like Dr. Doom, and Azamax, but they only offer short-term control. There must be something about the thin tender leaves that Spider Mites go after in a big way.
All of that being said, it is quite a pleasant plant that grows easily. It does not flower as readily as its very close cousin H. multiflora. I have found on this one that you need to let it grow quite high to produce blooms. It is also very adaptable to twisting around trellises. I know nothing about the origins of this plant and whether or not its speckles are man made or natural. If it were not for the spider mite problems, I could recommend this plant quite strongly, but because of it, I would ask you to consider a plain old green multiflora, which is far easier to care for with the blooms being almost identical.
I have also developed a video tour of the plant which can be seen below.
**UPDATE** I have just recently had to throw the plant out, even though it had two peduncles full of open flowers, because of the worst Spider Mite infestation that I have ever been witness to. The plant was literally crawling with hundreds of the little buggers. I cannot in good conscience recommend this plant to anyone unless you want to use it as a trap plant for Spider Mites. Stick with the plain green H. javanica – you will be much happier!
