The Tropical Food Plants Conservatory at Montréal Botanical Garden is newly-renovated, and is one of the highlights of a visit to the many MBG glasshouses. Most of the other glasshouses had plant displays with little interpretation. By contrast, the Tropical Food Plants Conservatory had an excellent mix of plants, interpretative signage, and accompanying displays. Well worth the visit!
Pineapple was previously featured on BPotD a few years ago: Ananas comosus (worth revisiting for an interesting link about “pressure and the keratolytic effect of bromelain”).
Wild relatives of the pineapple are native to southern Brazil and Paraguay. It was cultivated and spread throughout South and Central America by indigenous peoples prior to European arrival. Within 150 years, it was introduced into cultivation in many tropical and subtropical regions around the world as the fruit was valuable in the prevention of scurvy.
Cal’s Plant of the Week featured Ananas comosus in March of 2001, and it includes a photograph of a plant in flower (you may want to compare that flowering bromeliad with Tillandsia lindenii from a few days ago).
Wikipedia has a fairly detailed account on pineapples with a good set of references for additional reading.
