Areca Palm

According to NASA and Dr. B. C. Wolverton, the areca palm filters xylene and toluene from the air. Wolverton also specifies that, at 1.8 m (5 ft 11 in) in height, the plant will transpire 1 liter of water per 24 hours, thereby making it an effective humidifier.

It is grown as an ornamental plant in gardens in tropical and subtropical regions, and elsewhere indoors as a house plant. It has gained the Royal Horticultural Society's Award of Garden Merit.

One of several common names, "butterfly palm" refers to the leaves which curve upwards in multiple stems to create a butterfly look.

In its introduced range, this plant acts as a supplier of fruit to some bird species which feed on it opportunistically, such as Pitangus sulphuratus, Coereba flaveola and Thraupis sayaca species in Brazil.

Chrismas Cactus, Schlumbergeras

A beautiful holiday plant,(botanically known as Schlumbergera or Zygocactus) blooms at Christmas and also sometimes around Easter time if cared for properly. A month prior to Christmas you will be able to watch the tips of the leaves beginning to grow. The tips grow darker as each day passes, until a bud forms. At Christmas time, as if by magic, the buds open to a beautiful flower that will add colour and warmth to any holiday season.
