4. Plant Description and Characteristics
Agave stricta ‘Rubra’ is a slow-growing, clumping succulent perennial that forms a tight, nearly spherical rosette, typically reaching between 1 to 2 feet in height and width. The distinctive feature lies in its leaves: they are linear, and narrow, tightly packed, and stand rigidly upright, resembling a hedgehog’s spines. Each leaf has a rigid, slightly concave shape and tapers to a sharp, but not overly-sharp, pointed tip. The vibrant green color of the leaves transforms into a vivid red, particularly along the tips and margins, when exposed to full sun, intensifying the color. The textures can be smooth, but the leaf blades are rigid and tough. The ‘Rubra’ is specifically recognized for the intensity of its crimson coloration, a characteristic setting it apart from even closely-related varieties. The plant is monocarpic, meaning it flowers only once in its lifetime, usually after many years (possibly decades.) If it flowers, the bloom spike reaches upwards, bearing dense clusters of reddish-and-yellow flowers. After flowering, the plant dies, but it usually produces offsets (pups) allowing for the continuation of the plant.
