Oxalis+Triangularis




 * Oxalis triangularis **

 The "Love Plant" or "Fake/Purple Shamrock" as it is sometimes referred, is unique because of its purple, triangular shaped leaves, and small pink flowers that bloom in the spring. The plant also has a characteristic known as photonasty, meaning that the leaves of the plant respond to light, and in this case, the shamrock's leaves open during the day and close at night. This plant has its origins in Central America, such as Peru and Brazil. It's known to be found high in the mountains of Peru, which led to its tolerance of cooler temperatures, but not frost.
 * Historical Origin/Description: **

It seems to be used purely for ornamental purposes, though it's roots and flowers are edible. However, plants of the same family have more practical uses, like that of the Oxalis stricta, which has a yellow color and can be used to make a lemonade-like drink. There are others in the family that use the small blossoms for medicinal purposes.
 * Cultural Significance: **

 In the U.S., the Purple Shamrock has been popularized as a pot plant and is grown in many gardens and greenhouses across the United States. It is the only Oxalis that can be grown well indoors.
 * Cultivation in the U.S.: **

I think students could learn about the possible early uses of plants like these as food, and with that, the culture of a hunting and gathering society. It could be interesting to learn about plants' uses as food and a staple to one society and from there, how an edible plant can be turned into simply a decoration in a different society.
