Acanthus sp.

Acanthus montanus, also known as African mountain acanthus, False Thistle, Bear's breech, Mountain Thistle, and Alligator Plant, is a thinly branched unusual perennial with interesting foliage, basal clusters of oblong to lance-shaped glossy, dark green leaves reaching up to 12 inches long. The leaves have silver marks and wavy margins. It produces showy pink flowers in the summer to fall. It is said it is cold hardy to zone 9. The plant looks better in filtered light.

Several species, especially A. balcanicus, A. spinosus and A. mollis, are grown as ornamental plants.

Aeschynanthus radicans

Aeschynanthus is a large genus of Old World tropical herbs, similar to the genus Columnea in Central and South America. Both are often trailing epiphytes with large, showy flowers.

The appearance of the various Aeschynanthus species varies widely. The original "Lipstick Plant" has shiny, hard-surfaced leaves with bright red flowers that emerge from a dark red tubular calyx, resembling lipstick emerging from a tube. It is an epiphyte that grows in the angles of branches in the rainforest. As with all epiphytes, it does not live as a parasite on the tree, but takes its nourishment from fallen leaves and twigs that accumulate in the crevices of branches.

To care for the Lipstick Plant, it needs plenty of light but not direct sunlight. They thrive in summer heat, and winter temperatures should not drop below 60 degrees. It should be grown in semi-shade and needs regular or moderate water. If you live in a colder area, you can grow it in pots and make sure to water it regularly and keep the soil evenly moist.

Aeschynanthus sp.

A very attractive flowering vine, that is mostly used in hanging pots. Water freely durning spring to fall, but keep the soil a little drier in the winter. The trailing stems can be 2ft long, so they may need pruning after flowering has finished. The plant tolerates most house temperatures. Ideal temperatures are 60 degrees at night but 10 to 15 degrees higher during the day. A. pulcher is one of the classic lipstick plants, and is similar to A. lobbianus -- except for the tan colored calyx.
