Agave palmeri (also known as Palmer's century plant) is an especially large member of the genus Agave , in the family Asparagaceae. It is native to southern Arizona, southwestern New Mexico, Sonora and Chihuahua. [1] [2] [3] The plant is also frequently cultivated as an ornamental in other regions. [4]

<i>Agave</i> A genus of flowering plants closely related to Yucca (e.g. Joshua tree). Both Agave and Yucca belong to the subfamily Agavoideae.

Agave is a genus of monocots native to the hot and arid regions of Mexico and the Southwestern United States. Some Agave species are also native to tropical areas of South America. The genus Agave is primarily known for its succulent and xerophytic species that typically form large rosettes of strong, fleshy leaves. Plants in this genus may be considered perennial, because they require several to many years to mature and flower. However, most Agave species are more accurately described as monocarpic rosettes or multiannuals, since each individual rosette flowers only once and then dies ; a small number of Agave species are polycarpic.

Asparagaceae family of plants

Asparagaceae is a family of flowering plants, placed in the order Asparagales of the monocots. Its best known member is Asparagus officinalis, garden asparagus.

Description

Agave palmeri is the largest Agave species growing in the United States. It produces a basal leaf rosette of fleshy, upright green leaves of up to 120 cm (4 ft) in length, with jagged edges and ending in thick spines of 3–6 cm (1.2–2.4 inches) long. Flowers are pale yellow and green and 1.6–2 inches long and grow on branches in the upper third of the flower spike, which can be between up to 5 m (16.5 feet) tall. [2] [5] [6]

Rosette (botany)

In botany, a rosette is a circular arrangement of leaves or of structures resembling leaves.

In plant morphology, thorns, spines, and prickles, and in general spinose structures, are hard, rigid extensions or modifications of leaves, roots, stems or buds with sharp, stiff ends, and generally serve the same function: physically deterring animals from eating the plant material. In common language the terms are used more or less interchangeably, but in botanical terms, thorns are derived from shoots, spines are derived from leaves, and prickles are derived from epidermis tissue.

A raceme is an unbranched, indeterminate type of inflorescence bearing pedicellate flowers along its axis. In botany, an axis means a shoot, in this case one bearing the flowers. In indeterminate inflorescence-like racemes, the oldest flowers are borne towards the base and new flowers are produced as the shoot grows, with no predetermined growth limit. A plant that flowers on a showy raceme may have this reflected in its scientific name, e.g. Cimicifuga racemosa. A compound raceme, also called a panicle, has a branching main axis. Examples of racemes occur on mustard and radish plants.

Cultivation

The plant requires a large pot but is very tolerant of a wide range of conditions, including temperatures of around –10 °C. [7]
