Agave americana 'Mediopicta Alba' is a striking cultivar of the well-known Century Plant, prized for its bold architectural form and distinctive variegated foliage. This impressive succulent features large, fleshy leaves with a prominent creamy-white central stripe, flanked by green margins. It makes a dramatic statement in gardens and large containers, adding a touch of architectural elegance and visual interest.
 
Key Features of Agave americana 'Mediopicta Alba'
Large Rosette: Forms a large, symmetrical rosette of thick, rigid leaves.
Creamy-White Central Stripe: Each leaf has a broad, creamy-white stripe running down the center.
Green Leaf Margins: The central white stripe is bordered by green edges.
Sharp Marginal Teeth: The leaf margins are armed with sharp, hooked teeth.
Terminal Spine: Each leaf terminates in a sharp, dark-colored spine.
Slow Growth: Grows relatively slowly, especially in cooler climates or containers.
Monocarpic Flowering: Like other Agave americana varieties, it is monocarpic, meaning it flowers once at maturity (typically after many years) and then dies. The flower stalk can be very tall and impressive.
 
Care for Your Agave americana 'Mediopicta Alba'
Light: Thrives in full sun, which enhances its variegation and overall health. It can tolerate some light shade, but the colors may be less vibrant.
Soil: Requires well-draining soil to prevent root rot. A sandy or gravelly soil mix is ideal. Ensure containers have drainage holes.
Watering: Water sparingly, allowing the soil to dry out completely between waterings. Agaves are very drought-tolerant. Overwatering is a primary cause of failure. Water less frequently during the cooler months.
Temperature: Tolerates a wide range of temperatures but is generally hardy down to around -9°C (15°F) for short periods once established. Protect from prolonged freezing conditions, especially when young or in containers.
Humidity: Adapts well to low humidity. High humidity can increase the risk of fungal issues.
 
Maintenance for a Thriving Agave americana 'Mediopicta Alba'
Removing Dead Leaves: As the plant ages, lower leaves will naturally dry out. These can be carefully removed to maintain a tidy appearance and improve air circulation. Wear thick gloves when handling agave leaves due to the sharp teeth and terminal spine.
Handling with Care: Be cautious when working around this agave due to its sharp teeth and spines, which can cause injury.
Monitoring for Pests and Diseases: Agaves are generally pest and disease resistant, but watch for scale, mealybugs, or fungal issues, especially in overly moist conditions.
Flowering Considerations: Once the plant begins to send up its massive flower stalk, be aware that the main rosette will eventually die after flowering. However, it may produce offsets (pups) before or during this process.
 
Propagation Methods for Expanding Your Collection
Offsets (Pups): The most common method. Mature Agave americana 'Mediopicta Alba' may produce offsets or "pups" around the base of the main plant. These can be carefully removed once they have developed their own root system and potted up individually. Allow the cut surfaces to callus over for a few days before planting.
Seed: Propagation from seed is possible but can be slow, and the resulting plants may not always retain the exact variegation of the parent cultivar. Seeds require specific conditions for germination.
 
Agave americana 'Mediopicta Alba' is a magnificent and relatively low-maintenance succulent that provides a dramatic architectural element to any landscape or large container. Its striking variegated foliage and impressive size make it a truly captivating specimen.
