Chenille plant

Acalypha hispida

Other names: Philippine medusa, Red hot cat tail. It can grow to be 1.5–3.7 m, and have a spread of 0.91–1.83 m, with potted plants being the smallest in growth. It can be grown from seeds as well as from cuttings. The plant is dioecious, and therefore there are distinct male and female members of the species. The female plant bears pistillate flowers which are 0.7 millimeters long and range in color from purple to bright red, and grow in clusters along catkins that can grow up to 50cm or more in length. This feature is the primary reason the plant bears the nickname “red-hot cat tail”. The pistillates will grow all year long as long as the temperatures are favorable. The leaves are large, oval and bright green to reddish copper.

Agave

Agave guiengola

The succulent leaves of most Agave species have sharp marginal teeth, an extremely sharp terminal spine, and are very fibrous inside. The stout stem is usually extremely short, which may make the plant appear as though it is stemless. During flowering, a tall stem or "mast" ("quiote" in Mexico), which can grow to be 12m high and Agave salmiana can be significantly taller. The panicle grows apically from the center of the rosette and bears a large number of short, tubular flowers and sometimes vegetatively produced bulbils (a form of asexual reproduction). After pollination/fertilization and subsequent fruit development, in monocarpic species, the original rosette dies. However, throughout the lifetime of many Agave species, rhizomatous suckers develop above the roots at the base of the rosette. These suckers go on to form new plants after the original rosette desiccates and dies. Not all agaves produce suckers throughout their lifetimes; some species rarely or never produce suckers, while others may only develop suckers after final maturation with inflorescence. Some varieties can live for 60 years before flowering.
