Hoya linearis is widely regarded by Hoya enthusiasts as one of the most difficult Hoyas to grow, and I agree 100 percent! I no longer grow it, but would like to play around with it again. It is a really cool looking plant with a very long lasting flower, but keeping it alive is a real challenge that few can seem to master. I think it likes it very dry, and I have trouble with that. It will flower at a very young age from cuttings. Try this one at your own risk!
