My happiest surprise so far this summer has been the huge number of new leaves that my Hoya clemensiorum has put on. Usually I can count on only a couple of leaves per year from this plant, but the combination of a bonsai mix in a s-h pot and the greenhouse has produced a huge number of new leaves. At least 10 leaves and they continue to appear. I did not even know that this was possible! Another tip, this plant almost never needs water.
