Plant Description

Name: Agave americana var. oxacensis
Common Names: Oaxacan Century Plant, Oaxaca Agave

Agave americana var. oxacensis, commonly known as the Oaxacan Century Plant, is a striking variety of the well-known Agave americana. Native to the arid regions of Oaxaca, Mexico, this agave is appreciated for its bold, architectural form and striking foliage. The plant has thick, succulent leaves arranged in a rosette pattern. The leaves are blue-green with a hint of gray and have sharp, spiny margins with a distinct terminal spine at the tip.

This variety is smaller and more compact than the typical Agave americana, usually reaching a height of 1-1.5 meters (3-5 feet) and a spread of 1.5-2 meters (5-6 feet). The plant is known for its dramatic flowering spike, which can grow up to 6 meters (20 feet) tall and bears clusters of yellow flowers. This flowering event happens once in the plant's lifetime, after which the plant dies, but it usually produces numerous offsets or "pups" at its base before it blooms.

Cultivation of Agave americana var. oxacensis

Conditions:

1. Light: Agave americana var. oxacensis requires full sun to thrive, needing at least 6 hours of direct sunlight daily. It can tolerate some light shade, particularly in hotter climates, but full sun is ideal for maintaining its compact form and vibrant color.
2. Temperature: This agave is hardy in USDA zones 8-11. It prefers hot, dry climates and is highly heat and drought-tolerant. It can withstand occasional light frost but may require protection or mulching in areas where temperatures drop below freezing for extended periods.
3. Soil: The Oaxacan Century Plant thrives in well-draining soil, such as sandy or gravelly types, and does well in poor, rocky soils where other plants might struggle. Good drainage is essential to prevent root rot, which is a common issue in heavy, waterlogged soils.
4. Water: This variety is drought-tolerant and requires minimal watering once established. Water deeply but infrequently, allowing the soil to dry out completely between waterings. Overwatering should be avoided, especially in areas with high humidity or poor drainage.

Planting and Care:

1. Planting: Plant Agave americana var. oxacensis in the spring or fall. Choose a sunny location with well-draining soil. Dig a hole twice as wide as the root ball but no deeper. Place the plant in the hole, backfill with soil, and water lightly to settle the roots. Avoid planting too deep, as this can lead to stem rot.
2. Fertilization: Fertilization is generally not necessary for this agave. However, a light application of a balanced, slow-release fertilizer in the spring can promote faster growth. Avoid excessive fertilization, as this can encourage lush, weak growth more prone to rot and pest problems.
3. Pruning: Pruning is minimal and usually involves removing dead or damaged leaves as needed. Wear gloves when handling this plant, as the leaf margins are spiny, and the sap can cause skin irritation.

Propagation

1. Offsets (Pups): The most common method of propagation for Agave americana var. oxacensis is through the removal and replanting of offsets, or "pups," that grow around the base of the mature plant. Carefully dig around the base of the pup, gently pull it away from the parent plant, and allow it to dry for a few days to form a callous over the cut surface. Plant the offset in a well-draining potting mix and water sparingly until it establishes roots.
2. Seeds: Although less common, agave can also be propagated by seeds. Sow seeds in a well-draining soil mix and keep them in a warm, sunny location. Germination may take several weeks to months. This method is less common because it takes significantly longer for plants grown from seeds to reach maturity.
