Ananas comosus: Pineapple1

Edward F. Gilman, Ryan W. Klein, and Gail Hansen2


The 24- to 30-inch-long, stiff, bright green leaves have spiny tips and margins. Leaves arise from a tight rosette. Pineapples are often planted for their tropical appearance and as a horticultural novelty. The fruit appears on top of a central stalk after a year or more.

Use and Management

Although the plant will tolerate full sun to fairly dark conditions inside, pineapple is most attractive as an ornamental if given some protection from full sun. Well-drained soil is most suitable for best growth. The plant can be used as a specimen, or grouped as a groundcover in a mass planting. Plant on four-foot centers to allow plants room to spread their foliage. Do not plant in areas where children play because the spines can injure them if they contact the leaves.

The cultivar 'Variegatus' is grown for its striking variegated foliage and is quite popular.

Propagation is by dividing the suckers from the base of the parent plant and also by rooting the leafy top of a mature fruit.

Design Considerations

The bold form and coarse texture of the pineapple make it perfect for containers and highly visible spaces in the landscape. Use with plants that are softer with small foliage and low-growing mounding or spreading forms. Medium and light green foliage in the companion plants will highlight the bright green leaves of the pineapple. Pair with plants with more texture in the foliage to contrast with the smooth, stiff leaves. Use plants with small to medium flowers with cool, bright colors such as purples and blues to contrast with the golden color of the pineapple fruit. Use large masses of companion plants around the base or in front of the pineapples when they are planted in a mass.

Pests and Diseases

Mites, scales, and mealy-bugs can be serious pest problems.

No diseases are of major concern.
