Agave macroacantha, the black-spined agave or large-thorned agave, is a species of succulent flowering plant in the family Asparagaceae naturally occurring in Oaxaca and also near the town of Tehuacan in the State of Puebla, Mexico. [4]

Contents

Description

Agave macroacantha produces a medium-sized leaf rosette that can be basal or can grow on a very short stem. Leaves are succulent, greyish green and up to 1.8 feet long at a maximum, ending in sharp black spines that are up to 1.2 inches long at the tips. Flowers are small, grey and red, growing in bunches on sturdy stems of up to 3 m (10 feet) in height. [5]

Cultivation

The plant prefers a dry, sunny and hot location for summer and from early autumn onwards a cooler, well-lit space. It likes regular watering in summer and only minimum watering in winter, and will fare well in a large pot with sparse, gravelly soil. [6] [2] [7]

In the UK this plant has gained the Royal Horticultural Society's Award of Garden Merit. [8]

<i>Pachypodium lamerei</i> Species of plant

Pachypodium lamerei is a species of flowering plant in the family Apocynaceae. It is a stem succulent, photosynthesizing mainly through its trunk, and comes from the island of Madagascar, off the east coast of Africa. It has large thorns and leaves mostly just at the top of the plant, and large, fragrant flowers. The species has become one of the best known pachypodiums in cultivation, being relatively easy to propagate and grow. In cultivation it is often marketed as the Madagascar palm, despite its not being a palm at all. A variety called "Ramosum" has been described. It is distinguished mostly by a dwarf growth habit and its more rounded corolla lobe.

<i>Agave parryi</i> Species of flowering plant

Agave parryi, known as Parry's agave or mescal agave, is a flowering plant in the family Asparagaceae, subfamily Agavoideae. It is a slow-growing succulent perennial native to Arizona, New Mexico, and northern Mexico.

<i>Cleistocactus strausii</i> Species of cactus

Cleistocactus strausii, the silver torch or wooly torch, is a perennial flowering plant in the family Cactaceae. It is native to mountainous regions of Department Tarija, Bolivia, at 1,500–3,000 m (4,921–9,843 ft).

<i>Bergerocactus</i> Genus of cacti from North America

Bergerocactus emoryi is a species of cactus, known commonly as the golden-spined cereus, golden snake cactus, velvet cactus or golden club cactus. It is a relatively small cactus, but it can form dense thickets or colonies, with the dense yellow spines giving off a velvety appearance when backlit by the sun. From April to May, yellow, green-tinged flowers emerge, which transform into reddish, globular fruit. This species is native to the California Floristic Province, and is found in northwestern Baja California and a small part of California, in San Diego County and on the southern Channel Islands. Where the Mediterranean climate of the California Floristic Province collides with the subtropical Sonoran Desert near El Rosario, hybrids with two other species of cacti are found. It is the sole member of the monotypic genus Bergerocactus, named after German botanist Alwin Berger.

<i>Agave attenuata</i> Species of flowering plant

Agave attenuata, commonly called the foxtail or lion's tailagave or the swan's neck agave, is a species of flowering plant in the family Asparagaceae. Sometimes called the soft-leaf or soft-leaved agave, the aforementioned animal-related names are a nod to the appearance of the plant's inflorescence, which—after years, generally—rises slightly before gravity brings it back down, giving the bloom a curved, "swan"-like or "foxtail" look. The species' specific manner of flowering is unique in the genus Agave as most other species produce a towering, vertical display, reminiscent of a miniature tree.

<i>Agave victoriae-reginae</i> Species of flowering plant

Agave victoriae-reginae, the Queen Victoria agave or royal agave, is a small species of succulent flowering perennial plant, noted for its streaks of white on sculptured geometrical leaves, and popular as an ornamental.

<i>Agave mitis</i> Species of flowering plant

Agave mitis is a plant species native to the Mexican states of Hidalgo, Tamaulipas and San Luis Potosí, referred to as Agave celsii in many publications.

<i>Agave shawii</i> Species of succulent plant from North America

Agave shawii is a species of monocarpic succulent plant in the genus Agave, commonly known as Shaw's agave. It is a rosette-forming plant characterized by glossy, green leaves with toothed margins. After several years of slow growth, the plant puts all of its resources to produce a towering stalk of flowers, and then dies. The death of the flowering rosette is compensated by the growth of numerous clonal pups. This species is segregated into two subspecies, one native to the coast of southwestern California and northwestern Baja California, known commonly as the coast agave, and another native to the Baja California desert, known as the Goldman agave.

<i>Rhipsalis pilocarpa</i> Species of cactus

Rhipsalis pilocarpa, the hairy-fruited wickerware cactus, is a species of flowering plant in the cactus family that is endemic to Brazil. Scarce in the wild, it is known only in a small number of isolated locations. Its status is listed as “vulnerable” by the IUCN Red List. However, it is cultivated as an ornamental houseplant and as such has gained the Royal Horticultural Society’s Award of Garden Merit.

It is a small or medium-sized succulent plant that forms stemless rosette up to 3 feet (91 cm) across and up to 2 feet (61 cm) tall. The leaves are dark green to a bronzish-green in color and have very ornamental white bud imprints. The flower stalk is up to 11.5 feet (3.5 m) tall and is densely loaded with yellowish-green to dark purple flowers up to 2 inches (5.1 cm) long. Flowers appear in autumn and winter.

<i>Agave stricta</i> Species of flowering plant

Agave stricta, the hedgehog agave, is a species of flowering plant in the family Asparagaceae, native to Puebla and Oaxaca in Southern Mexico. 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. The foliage may develop a red tinge in the summer. The plant is also known to produce pincushion-like offsets as it grows.

<i>Agave potatorum</i> Species of flowering plant

Agave univittata, the thorn-crested century plant or thorn-crested agave, is a plant species native to coastal areas of southern Texas and northeastern Mexico, at elevations less than 100 m. It has been widely named Agave lophantha by botanists including Howard Scott Gentry, but the name A. univittata is older and therefore more in accord with nomenclatural rules of botany.

<i>Agave parrasana</i> Species of plant in the family Asparagaceae

Agave parrasana, the cabbage head agave or cabbage head century plant, is a flowering plant in the family Asparagaceae. A slow-growing evergreen succulent from North East Mexico, it produces a compact rosette of fleshy thorn-tipped grey-green leaves, 60 cm tall and wide. The leaves are blue green and the thorns are red. The whole plant may reach 100 centimeters tall and wide. Occasionally, mature plants produce a spectacular flower head up to 6m tall, opening red and turning yellow. This signals the death of the flowering rosette. However, offsets may form and continue growing.

<i>Agave titanota</i> Species of flowering plant

Agave titanota, the chalk agave, is a species of flowering plant in the family Asparagaceae. It is a medium-sized evergreen succulent perennial native to Oaxaca, Mexico. It often reaches 1-2 feet tall and 2-3 feet wide.
