In fact, there are many rare house plants that look like they’re from another planet. You can grow them in your home and use them to attract attention, start conversations, and please the eye. Start your search for some new greenery with these 19 rare house plants.

Goldfish Plant

An eye-catching addition to any home, the goldfish plant has trailing vines and many bright orange blooms that resemble schools of goldfish. Unlike some other house plants, this one has the potential to bloom all year long. A tropical epiphyte, the goldfish plant needs plenty of indirect light, humidity, and airy soil. In the summer, the plant needs you to frequently water it.

Pitcher Plant

This unique indoor plant is carnivorous. It attracts insects, then traps them inside. The pitcher plant has enzymes that then digest the caught insects. In addition to having odd habits, this plant also has an unusual appearance. To care for a pitcher plant, you need to give it lots of sunlight. It also requires warm temperatures and high humidity levels. If you live in a dry climate, you can expect to give frequent care to this plant. It will need regular misting and watering. The soil should consist of a sphagnum and perlite mixture.

    This unusual plant is definitely a conversation piece and fun for anyone, particularly children to experience and learn about carnivorous plants. If you have a fly or gnat problem in your home, this will surely help. Insects are naturally drawn to these plants and are lured into their pitchers, where they become trapped and eventually digested by the plant.

Desert Rose

The flowers on a desert rose look like something out of a magazine. For that reason, this plant is one of the rare house plants that makes a style statement. It’s relatively easy to care for, requiring infrequent watering. To survive, the desert rose needs warmth and plenty of bright sun.

Lobster Claw Heliconia

This plant has flowers that resemble the claws of a lobster. With its bright, unusual appearance, the lobster claw can be the focal point of any room. Also known as the parrot plant, this Heliconia is high-maintenance. It needs partial shade or full sun. The soil should be well-draining but also moist. If the soil is alkaline, the plant may not survive.
