Is there any way to have the flow command use the surface normal of an object to determine the rotation of the flowed object when flowing from curve to curve?

Im trying to wrap some leaves around a pearl for a piece of jewellery.
So Ive draw the leaf flat with a ref curve and trying to flow it on the surface of the sphere with a curve Ive drawn on the surface.
But the leaf rotates arbitrarily when flowed to the new curve.

Perhaps there is a more effective way to accomplish this?

thank
