King of The Agaves

About:

Common Names: None widely recognized, sometimes referred to as “Agave ferdinandi-regis” or “King Ferdinand Agave.”

This regal agave is an absolute stunner! Agave nickelsiae, formerly known as Agave ferdinandi-regis, is considered The King of the Agaves! – An absolutely stunning smaller to medium sized agave. A somewhat slower-growing agave, it maxes out at 2 ft tall and 30+ inches wide, making it an ideal agave for both your landscape as well as a potted plant.

It forms an open rosette of stout triangular blue-green leaves having narrow longitudinal white bud imprints that usually form a triangle shape. The margins of the leaves are dark reddish brown and spineless terminating at the blunt leaf tip in a stout spine of the same color. Plant in full sun in a well-drained soil. Very little irrigation required.

Appearance: Agave nickelsiae is a visually striking succulent featuring a compact rosette of thick, blue-gray leaves. These leaves exhibit prominent ridges and sharp spines along the edges, contributing to the plant’s distinctive architectural appeal.

Care:

Cold Tolerance: Hardy to temperatures as low as 10-15°F.

Sun Requirements: Prefers full sun to partial shade and thrives in bright, indirect light. Provide late afternoon shade during intense late summer sun.

Watering Needs: Requires well-draining soil to prevent root rot. Water sparingly, allowing the soil to dry out between waterings. Overwatering can lead to rot, while underwatering may cause dehydration.

– Root Rot: Ensure well-draining soil and avoid excessive watering; remove affected parts and repot if necessary.
– Frost Damage: Protect from frost with frost cloth or bring indoors during cold spells.
