As of May 2019, the World Checklist of Selected Plant Families and Plants of the World Online recognize about 270 species of Agave plus a number of natural hybrids. This includes species formerly placed in Manfreda and Polianthes . [ 1 ]
Agave sanpedroensis is a perennial rosette-forming plant with succulent leaves, 50–70 cm tall and wide and producing abundant offsets. The leaves are stiffly upright, gray to grayish green, with conspicuous banding and white bud-imprinting, and undulate margins.
Agave amica, formerly Polianthes tuberosa, the tuberose, is a perennial plant in the family Asparagaceae, subfamily Agavoideae, extracts of which are used as a note in perfumery. Now widely grown as an ornamental plant , the species is native to Mexico.
The flowers come in groups of 1-4 flowers, mostly in spring. After blooming, the agave dies. [7] The fruit are small, ovoid capsules, between 6-10 millimeters in diameter; seeds are wedge-shaped and half-round. [8] The plant has slow to moderate growth, as does most of its genus.
Agave maculata was first described by Eduard von Regel in 1856. Later, in 1859, William Hooker described the same species as Agave maculosa.It was under this synonym that it was transferred to the genus Manfreda and then the genus Polianthes (both now included in Agave), but Regel's epithet is the oldest and so has priority.
Agave stricta, the hedgehog agave, is a species of flowering plant in the family Asparagaceae, native to Puebla and Oaxaca in Southern Mexico. [4] Growing to 50 cm (20 in) tall, it is an evergreen succulent with rosettes of narrow spiny leaves producing erect racemes, 2 m (7 ft) long, of reddish purple flowers in summer.
Agavoideae is a subfamily of monocot flowering plants in the family Asparagaceae, order Asparagales.It has previously been treated as a separate family, Agavaceae. [1] The group includes many well-known desert and dry-zone types, such as the agaves and yuccas (including the Joshua tree).
As with other Agave species, the species is monocarpic, meaning that, rather than sending flowers out from the side of its stem and continuing living (like the succulent genera Crassula or Sedum, for example), the entire rosette morphs into the giant inflorescence. After many months, this blossom subsequently dies following pollination and seed ...
