My Hoya polyneura just rooted after a couple of weeks in a plastic bag with moist and well draining soil. It even grew a few extra roots along the stem to stay hydrated in the plastic bag. I really like this one because of its visible veins and thin leaves. Sometimes they appear to glow because sunlight can pass through the thin parts of the leaves.
This one is apparently fairly hard to keep alive, so I hope my green thumbs are enough to help it thrive in my apartment.
