Red foliage on a holiday plant, such as the Christmas cactus [Schlumbergera and Zygocactus spp] indicates new growth. The Christmas cactus is native to Brazil, where the growing and dormant seasons are the reverse of the Northern Hemisphere. In fact, it's called a winter blooming cactus, because of its growing season overlapping with the timing of northern winters.
Some examples of plants with red foliage or flowers include red maple trees, red roses, red hot poker plants, and red Japanese maple trees.
A cactus terrarium needs some sort of free drainingsoil that holds some moisture. It also needs some sort of drought resistant vegetative cover. Cooperative candidates include succulent plants, to which the cactus is related. They also include native wildflowers of the Great Plains and Desert Southwest, in the United States of America.

In the way of another example, cottonwood [Hibiscus tiliaceus] has a colorful yellow bloom, and is a cooperative subject for the art of bonsai gardening.
The variegated plants, like the Caladium, have leaves that are never green. They come in a variety of colors and patterns, including white, pink, and red. These plants are prized for their colorful foliage.

An angiosperm, or flowering plant, such as the Christmas cactus [Schlumbergera and Zygocactus spp] is unusual, because of its native environment. The holiday cactus is native to the Brazilian rain forest. The extreme environment of subtropical and tropical environments demands certain changes for a plant to survive. So, for example, the holiday cactus has airy roots that don't grow out of soil. It also has green or red grape like inedible fruit that mustn't be bitten into, chewed, or swallowed. Also, it has strongly colored flowers that are set off by leafless, notched stems. And despite the preceding environmentally influenced peculiarities, it has winning tendencies to adapt and fit right into the business and home with other house and office plants.
The redcap cactus, or Gymnocalycium mihanovichii, is a small, colorful cactus with bright red tops. It is commonly used in the horticultural trade for its ornamental value and is popular as a houseplant due to its small size and striking appearance.
