String of Pearls Plant (Senecio Rowleyanus) I love these.A friend gave me a string of pearls plant several years ago. Mine got somekind of disease and I lost it. Haven't been able to find another since.
Passion Flower Vine* Exotic flowers like these don't have to be limited to tropical gardens. A vigorous perennial vine that climbs via tendrils, the passion flower can be a conversation piece in the garden.
