Agave Glossary

One of the most popular agave species, formally known as Agave titanota. It features thick leaves and sharp spines with a compact rosette form. Numerous variations exist depending on origin and selected cultivars.

Agave oteroi — a species reclassified from plants formerly sold as A. titanota. The distinction between oteroi and titanota remains debated among experts.

A named cultivar of Agave titanota. It features wide leaves and prominent white spines with a compact form. Selected in Taiwan, it is one of the most sought-after titanota cultivars.

A named cultivar of Agave titanota known for its thick white spines and wide leaves, giving it a powerful appearance. It is an iconic cultivar of the agave boom and remains consistently popular.

A small new plant that emerges from the base or underground stem of the parent plant. Once large enough, it can be separated and grown independently. Pupping is one of the primary propagation methods for agave.

A plant sold with its roots trimmed or removed, typically for import quarantine or shipping purposes. Bare root plants require rooting management after purchase and are generally less expensive than rooted specimens.

The process of encouraging new root growth on a bare root plant. Methods include hydroponics, soil culture, and sphagnum moss. Temperatures of 25–30°C with adequate humidity and air circulation are key. Rooting can take weeks to months.

Transplanting into a slightly larger pot as the plant grows, keeping the root ball intact. Best done during the spring to early summer growing season. Moving to an excessively large pot increases the risk of root rot.

A watering method where the pot sits in a tray of water, allowing absorption from the bottom. Used for rooting management and seedling care. The tray is refilled as it dries rather than kept constantly full. Prolonged use can cause root rot.

Sharp projections growing at the leaf tips and margins of agave. Spine color, shape, and size are defining features of each cultivar. Variations include white, black, and red spines, greatly affecting ornamental value.

The radial leaf arrangement of an agave, resembling a rose bloom. Agaves naturally grow in rosette form, and plants with well-balanced leaf count, angle, and width are most highly valued.

A plant's ability to withstand low temperatures. Cold hardiness varies widely among agave species — Parryi types can survive below -10°C, while Titanota types suffer damage below 5°C. Many species need indoor care or insulation in winter.
