Light: The Jade necklace is an unusual, trailing variety of crassula (perfect hanging where she can show off!) She's happiest in a sunny spot with bright light.
Water: She's a succulent, which means she needs very little watering as she stores water in her fleshy leaves. Best to giver her a little drink once her soil has dried out completely. We prefer to water her from the bottom and letting her drain off before returning to her pot.
