Ananas comosus 'Corona'

The Costa Rican breeding origin of Ananas comosus ‘Corona’

Chester Skotak Jr selected the compact pineapple sold as ‘Corona’ in Alajuela, Costa Rica, in 2005 from a planned cross between two unnamed Ananas comosus seedlings. Tissue-culture propagation began in 2006.

Pineapple ancestry lies in tropical South America, especially southern Brazil and Paraguay, although people spread the crop widely before European contact.

Care for bromeliad rosettes

Support, pruning, handling and leaf care

A stable pot normally supports Ananas comosus ‘Corona’; a fruiting stem may need one loose stake if its weight pulls the rosette sideways. The original rosette gradually declines after fruiting, so retain healthy basal offsets to replace it rather than forcing the old centre.

Humidity and airflow

Average household humidity is sufficient for Ananas comosus ‘Corona’. Gentle airflow through the rosette helps any cleaning water evaporate and keeps the substrate surface fresh.

Light

Place Ananas comosus ‘Corona’ directly beside a bright south-, west- or east-facing window and acclimate it to several hours of direct sun. Strong light keeps the basal rosette compact and supports any developing fruit and offsets.

Watering

Water Ananas comosus ‘Corona’ when the upper third of the pot has dried, then soak its shallow root zone and let the container drain completely. Avoid leaving stale water in the central rosette indoors.

Substrate and roots

Use a loose, fast-draining bromeliad mix for Ananas comosus ‘Corona’, combining quality potting substrate or coir with fine bark and pumice or perlite. The root system is relatively shallow and needs air, not a deep mass of wet peat.

Repotting

Repot Ananas comosus ‘Corona’ when roots and offsets fill the pot, the fruiting rosette becomes unstable, drainage slows or the old mix collapses. Work in stable warmth, maintain the stem depth and separate an offset only after it has developed its own roots and useful size.

After the ornamental pineapple fruits

• The fruiting mother rosette slowly declines and pups appear: A pineapple rosette fruits once, then naturally gives way to offsets. Keep healthy pups growing while removing only fully dead mother leaves; separate a pup later when it has enough size and roots to establish.
• The small fruit stops enlarging or begins to age: ‘Corona’ is grown as a compact ornamental pineapple, not for a full grocery-sized crop. Fruit size is not reliably increased indoors, and the stalk should be removed only when the fruit and stem have clearly finished.
• The central leaves pull out and smell sour: This is consistent with crown rot, often after water has remained in a cool, poorly ventilated rosette. Remove soft tissue, keep the centre dry and inspect the root zone before watering again.
• Leaf tips and margins turn brown: A dry spell, salt build-up or physical rubbing can mark the stiff blades. Flush the mix, keep watering more even and trim only the dead tip without cutting into live green tissue.
• White cottony patches or sticky brown shells appear low in the rosette: Mealybugs and scale can hide between the armed leaves. Isolate the plant and inspect all pups as well as the mother; use our mealybug guide for cottony infestations.

Ananas comosus ‘Corona’ has sharp parts

• This plant is non-toxic to cats and dogs. Its effects on people are unclear.
• Sharp spines or rigid plant parts can puncture the mouth, eyes, skin or paws.
• Handle it carefully. Contact a veterinarian or medical professional after a serious injury, especially to the eye.

Why is it called Ananas comosus?

Ananas comes from an Indigenous South American name for pineapple, recorded in Tupi-Guaraní languages and carried into European botanical vocabulary. The Latin epithet comosus means tufted or leafy, describing the crown above the fruit.

Philip Miller established the genus Ananas in 1754 in The Gardeners Dictionary Abridged, fourth edition.

Carl Linnaeus first described it as Bromelia comosa in 1754 in Herbarium Amboinense, page 21. Elmer Drew Merrill later placed it in Ananas as Ananas comosus in 1917 in Interpretatio Herbarii Amboinensis, page 133.
