I received these seeds as
G. patersoniae, but after a careful look at the reference books I am convinced that they're
G. gracilis. Several species of glads come in shades of pale ice blue and light violet, including
G. violaceo-lineatus, G. gracilis, and
G. patersoniae. They're all small, delicate-looking, sweet-scented, and yet very durable and easy to grow. They also turn out to be great parents for hybrids.
