Can you tell me if this hoya is suppose to have a reddish color to the top of its leaves? Or is that a problem? I put it outside about 3 weeks ago, from inside on a window sill, it wasn't doing anything there. Now it is putting out a new stem and all the old leaves on the first stem are all reddish. The undersides are solid green. It is still growing fine on both stems.

This is the hoya that is suppose to have lilac smelling flowers on it, when it blooms. Anyone growing it? I would love to see the bloom. I am in south Fla. it is outside now, and on a shaded northern front porch, getting maybe direct sun for 2 hrs in the early morning. Do I have a problem, or is it finally getting the light it needs?
