The Echeveria Ruffles have long, flat, pale green leaves with beautiful red edging - made only more intense the more sun it gets.
Like most succulents, Echeveria like multiple hours of direct sunlight a day and well-draining soil. Let the soil dry out completely between waterings. When watering, avoid letting water sit within the rosette, as these dudes are prone to root rot if left in sitting water. Also, be sure to trim any dead or dying lower leaves (natural as the plant grows) to avoid getting mealy bugs.
