I only found out that these are the flowers of the wild garlic plant from South Africa while reading the National Park's Board publication '1001 Garden Plants in Singapore'. The second edition is really a gem as it is better organised. The layout is attractive and it is so easy to look up the names of plants or trees by scientific or common names. The binding is also an improvement over that of the first edition. My earlier copy came apart and the book was in shambles even though I had taken good care of it. What is great is also the inclusion of Chinese characters for the names of the plants.
