Rather rare succulent and extremely showy for its overall appearance consisting of pretty drooping leaves, perfect also for shelves or hanging vases. Like all species of this family, it is a plant with a perennial bulb underground, from which annually branch out nastriform leaves, extremely thin but very long and pointed at the apex, which take on shades of a lively emerald green. One of the distinctive features of S. undulata, as the name suggests, is the presence of gently undulating margins, which contribute to conferring three-dimensionality to the entire specimen and make it absolutely unmistakable!
