Ananas comosus or Pineapple makes a distinctive houseplant. Pineapple is a rosette plant with long, narrow leaves bearing sawtooth edges. Pineapples are native to Tropical America.
Blooming Time: It takes 2 years for the plant to mature enough to bloom and produce fruit. The fruit is produced on top of a sturdy stalk at the center of the plant. Homegrown pineapples are not as large as commercial pineapples.
Culture: Ananas comosus need full sun and temperatures above 68° F. We use a soil mix consisting of 2 parts peat moss to 1 part loam to 1 part sand or perlite. Allow the plant to dry in-between waterings. Fertilize every 4-week with a balanced fertilizer diluted to ½ the strength recommended on the label.
Propagation: Ananas comosus are propagated by cutting the leafy top from a commercial pineapple. Make sure to clean all of the yellow fruit from the leaf top. Peel 4 layers of leaves off and root in water or damp sand-peat mix. After roots appear, transfer to an 8-inch pot for growing. They are also started from offshoots from the main plant.
Ananas comosus was featured as Plant of the Week March 30-April 5, 2001.
