It is best to keep your succulent indoors, in direct sunlight. Please visit my post "Jelly Bean Plant–Sedum Rubrotinctum" for more information and images. Blue Rose Echeveria is a species of succulent that has been called Hen and Chicks. This is because the new rosettes grow so close to their mother plants, much like baby chicks who are huddled together with their mother.

Overwatering is the most common cause of succulent plant deaths. It could also lead to dead air plants. This plant can grow to a maximum of two feet in height and width in sunny, warm climates. With a south or west-facing window, you'll likely need to place your succulent a few feet away, but you may be able to keep your String of Hearts directly in a north or east-facing window.
