Ananas comosus 'Variegatus' Variegated Pineapple1
Introduction
The 24 to 30-inch-long, stiff, bright green leaves have spiny tips and margins (Fig. 1). 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 plants 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. They can be used as a specimen, or grouped as a groundcover in a mass planting.
Plant on fourfoot 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.
Mites, scales, and mealy-bugs can be serious pest problems.
Pests and Diseases
No diseases are of major concern.
