Origin and Habitat: It seems that Agave potatorum cv. Cubic sprang up from a tissue culture done in the lab at the Shady Oaks Nursery (but not sure, we need confirmation).

Description: Agave potatorum cv Cubic is one of the strangest Agave cultivar. This cute little form of Agave potatorum has unique ridges on the backs of the leaves giving it a cube-like appearance, hence the name. It is a very different cultivar that almost seems monstrose.
Rosettes: Compact, open spreading, symmetrical, hemispherical in shape up to 30 tall by 45 wide (but usually smaller).
Leaves: The leaves grow as if 2 leaves are fused together resulting in some of them having a three or four angled appearance and forming a square shape. The edges are a purplish/maroonish colour. The leaves have large rusty coloured teeth and a long sharp terminal spine that contrasts well with the pale leaf colour. Marginal spines can grow on up to all four of the leaf sides.
Flowers stalk: Bloom-stalk size and flower colour, unknown.
Remarks: There is not a lot of information about this cultivar and some of it seems to conflict.
Subspecies, varieties, forms and cultivars of plants belonging to the Agave potatorum group
- Agave potatorum Zucc.: Small Agave, growing solitary or slowly clumping, that forms an compact to open symmetrical succulent rosette. It is a very polymorphic species with a large range of variability and the size.
- Agave potatorum f. compacta hort.: Dwarf cultivated form that grows eventually up to 20(-30) cm tall and in diameter. The leaves have distinct showy bud-imprints.
- Agave potatorum Tlaxiaco, Oaxaca, Mexico: This population has very nice bright orange marginal teeth.
- Agave potatorum var. verschaffeltii A.Berger in A.Berger: The old name ''verschaffeltii '' is still in use to distinguish plants with sinuous leaf margins and with teeth atop of outward-projecting bumps.
- Agave potatorum cv. Cubic: The leaves grow as if 2 leaves are fused together resulting in some of them having a 4 angled appearance and forming a square shape. Marginal spines can grow on up to all four of the leaf sides.
- Agave potatorum cv. Kichijokan: Variegated form with amazing symmetrical lotus like leaf pattern. The leaves have lateral, creamy-coloured variegations. Nice imprints are present on the back side of the leaves. The edges have large rusty coloured teeth and are a purplish/maroonish colour.
- Agave potatorum cv. Shoji-Raijin hort.: Also called 'Blue rose' it is tiny rosette of plump blue leaves that stay very small and compact. It produces offsets and forms a small clump of 6-7 cm rosettes. Mature plants stays in 10 cm pots only.
- Agave potatorum cv. Shoji-Raijin variegata marginata hort.: Has a creamy-white or pale-green irregular stripe on the edge of the leaf.
- Agave potatorum cv. Shoji-Raijin variegata mediopicta hort.: Has a broad white band down the centre of each leaf.

Cultivation and Propagation: Agave potatorum cv Cubic is a easy-to-grow species, but isn’t a super fast grower. It grows as a solitary symmetrical rosette, but may produces a few plantlets around its perimeter. Makes a great container plant for the patio.
Growth rate: The growth rate is moderate, taking several years to achieve full size.
Soils: Grow it in porous soil with adequate drainage.
Light requirements: It may tolerate full sun, but it grows best in partial shade or morning sun and benefits from filtered shade.
Waterings: Water thoroughly when soil is dry to the touch. In winter watering this plant can be done once every 1-2 months, there is no need to mist the leaves.
Hardiness: It is supposed to be hardy to -3° C, particularly when dry but it is best to avoid severe freezing temperatures.
Heat Tolerance: Good.
Propagation: It can only be grown from offsets. Remove the basal suckers in spring or summer and let the cuttings dry for a few days before inserting in compost. only problem is the logistics of getting to the suckers - very sharp spines and suckers usually right up against, or underneath the mother plant.
Uses: Often used in a pot as a patio plant, they make an eye-catching statement and along with other evergreen plants in pots, can be moved around to change the scenery or position to give more shelter.
