Houseplant Types

There are seven main categories of plants:

1. Bromeliad: These are related to the pineapple. Most are stem-less and the "cup" that they sit in should be kept full of water.

2. Cactus: Succulent plants are noted for their spines. They are specially adapted to dry conditions and are usually leafless. The stems store water. Most have thick skins to reduce evaporation and many produce large and beautiful flowers.

3. Epiphyte: These plants are air-plants that grow naturally without soil. They support themselves on trees or rocks in their natural habitat. Most epiphytic houseplants are from the tropics.

4. Fern: These plants have no flowers but are known for their beautiful, lacy leaves. Most thrive in a high humidity with filtered sunlight and cool, but not damp, roots.

5. Gesneriad: This family of plants usually has hairy leaves. Propagation is usually by stem or leaf cuttings.

6. Orchid: Known for their gorgeous blossoms, orchids are one of the largest plant families, and many can be grown successfully indoors. All require high humidity and bring light (but not direct sun).

7. Succulent: Succulent is a descriptive term, rather than a family name. For instance, most cacti are succulents, but many succulents are not cacti. Succulents have thick, fleshy parts that are used to store water during dry seasons in their natural habitats. Most are slow-growing and need dryness, well-draining soil. They require little attention to thrive.
