Iris pseudacorus (Iridaceae)
"...and she laid it in the flags by the river’s brink" (Exod.2:3).
"Can the rush grow up without mire? Can the flag grow without water?" asked Job rhetorically (Job 8:11). The yellow flag iris certainly flourishes on wet marshy ground. It grows in shallow water on the edges of ponds and streams. The flowers are a deep yellow. It is not a Palestinian plant. Other types of iris, however, such as Iris nazarena (Nazareth iris) and Iris costeti (Costet’s iris), provide some of the loveliest sights of Galilee in the early spring.
