Pineapple Red plants are intolerant of frost and will weaken and show damage from winter temperatures significantly below 60 degrees F. Outdoors, pineapple plants typically grow 3-4’ tall (leaves to 3’ or more and fruit to 1’ taller) and as wide. Stiff, tough, narrow, sword-shaped, evergreen, gray-green leaves usually with sawtoothed edges appear in basal rosettes. Prior to flowering, the stem in the rosette center lengthens and enlarges. Purple or red flowers (50-200) then bloom in a large inflorescence. Topped by a compact crown of leaves, the pineapple fruit (a syncarp) forms and matures to 12” long or more with a weight up to 14 pounds.
Planting & Caring –
The plant is best grown in acidic, loose, sandy, organically rich, well-drained soils. Indoor plants require consistently moist soil, bright sun, high humidity and an air temperature that does not dip below 65 degrees F. Fruits may not appear on indoor plants during the first few years. Indoor fruits are usually quite small and not particularly tasty but are ornamentally attractive.
