Taipei, April 18 (CNA) The Council of Agriculture said Wednesday that it has collected 17 species of oxalis for observation and cultivation to find which kind grows best in Taiwan, given the plant's increasing popularity.
There are over 900 known oxalis species around the world, and the plant can be spotted in any corner of the world except for polar regions, said the Taiwan Seed Improvement and Propagation Station under the council.
The three-leafed plant has drawn much attention in gardening circles in recent years, so the station plans to observe the existing species and cultivate kinds that are most suited to Taiwan's environment, the station added.
Oxalis, which originated in South Africa and South America, consists of three heart-shaped notched leaflets. A four-leaved oxalis is seen as "lucky."
