The Asiatic Dayflower

Asiatic dayflowerOne of the instructions we received as children when we went looking for Spanish needle plants for our rabbits, was to avoid picking water grass.

It was said that while water grass was good for feeding other animals, it is known to cause diarrhea in rabbits.

This water grass – a weed,  is none other than the Asiatic Dayflower (Commelina communis); in some places it is grown as a creeper plant. It is called Dayflower as its flower blooms for only one day.

The Asiatic Dayflower belongs to the Monocot division of plants which most notably contains the Grasses. It is also called Monsoon flower, Mouse flowers and Mouse Ears.  Asiatic dayflowerThe Asiatic Dayflower is eaten raw in salads, and can be lightly cooked with other vegetables. The seeds are also edible.
