Agave Ferdinandi-Regis

The Agave Ferdinandi-Regis, also known as King Ferdinand’s Agave, is one of the most iconic Agaves in the plant world. Appreciated for its architectural habit and its almost spherical dense rosette, this succulent plant stands out for its extreme elegance. Each thick, dark green and rigid leaf is highlighted by marked white lines that follow the margins and the center, as if hand-drawn. These characteristic stripes make it a true vegetal work of art.

Compact and geometric, Agave Ferdinandi-Regis grows slowly and remains small, rarely exceeding 45 cm in diameter at maturity. Its perfect appearance makes it a preferred subject for lovers of sculptural and minimalist plants. It is a rare species, often cultivated in pots for close observation, but it can also be integrated into a dry garden or rockery, provided it receives good winter protection.

Thanks to its slow growth, this agave requires little maintenance, apart from good light, a perfectly draining substrate and moderate watering. It delights collectors and is often considered a centerpiece in a succulent collection.

Agave Ferdinandi-Regis is native to the semi-desert areas of northeastern Mexico, mainly in the limestone mountains of the states of Coahuila and Nuevo León. In its natural habitat, it grows on well-exposed rocky slopes, often among stones, which explains its strong drought tolerance and its need for perfectly draining soil.
Agave Ferdinandi-Regis requires very bright exposure to remain compact and preserve the vividness of its white lines :

🌞 Outdoors : direct sun, at least 6 hours per day.

🌤️ Indoors : place it behind a south-facing window or under horticultural lighting.

💡 Tip : the brighter the exposure, the more pronounced the contrast of the white patterns.
Agave Ferdinandi-Regis is very sensitive to stagnant moisture :

💧 Spring / summer : water only when the substrate is completely dry, about every 15 to 20 days.

🍂 Autumn / winter : greatly reduce or stop watering depending on conditions.

⚠️ Advice : in pots, avoid saucers filled with water and choose a container with drainage holes.
Adapted to arid climates, Agave Ferdinandi-Regis is fairly hardy if kept dry :

🌡️ Ideal : between 20 and 30 °C during the growing season.

❄️ Tolerance : down to –5 °C if the soil is perfectly drained.

🏠 Wintering : bring it indoors as soon as temperatures drop below 5 °C in humid climates.
🪨 A draining soil is essential to prevent root rot: cactus substrate base, 30 to 40% perlite to aerate and complete with 20% pozzolana to ensure deep drainage
Agave Ferdinandi-Regis flowers only once, at the end of its life :

🌸 Flowering : after 15 to 20 years in cultivation, depending on conditions.

📏 Flower stalk : very tall (up to 3 m), bearing pale yellow flowers.

💀 After flowering : the rosette dies, but may produce offsets if the plant is well developed.
