Echeveria 'Rain Drops' is a small succulent that forms a rosette of pale green, spoon-shaped leaves with reddish margins and a spherical, blue-green bump in the middle of each leaf toward the tip. The rosette can grow up to 6 inches (15 cm) in diameter, usually solitary, but may form a few offsets as it matures. Not all young specimens have bumps, but they will develop with time.
The bell-shaped flowers are pinkish outside and yellow inside. They appear on branched stalks that rise well above the rosette in summer.
