A true collector's agave, Agave titanota 'Black and Blue' is admired for its dramatic contrast of powdery blue-grey leaves lined with bold black teeth and a striking black terminal spine. The thick, sculptural leaves form a compact, symmetrical rosette, making this one of the most sought-after ornamental agaves for succulent enthusiasts.
 
This slow-growing variety develops exceptional colour and spine definition when grown in bright light. Whether displayed in a decorative pot, succulent collection, rock garden, or xeriscape, 'Black and Blue' makes an impressive statement plant with very little maintenance.
 
As it matures, the rosette typically reaches 30–60 cm tall and 60–90 cm wide, remaining compact for many years. Like most agaves, it is monocarpic, producing a spectacular flower spike after many years before the main rosette dies.
