I suppose the early forget-me-not (Myosotis ramosissima) is not really a weed of cultivation,it is a small plant that manages to survive in dry, barren places and that includes pavements and gutters. It grows quite readily on the roadsides here where I live. It can also be found on rocks and walls near the sea.
It is a small plant, probably due to lack of nutrition from the hostile environments it grows in and also to its inability to get a firm foothold to support anything bigger. Each flower is tiny but indisputably 'forget-me-not' shaped. Usually there is a small cluster of three or flowers at the top of the stem and below that are seed pods from earlier flowers that have been pollinated. Each seed pod is at the end of a small stalk ans the stalks run alternately opposite up the stem. Although my reference book says that this plant flowers from April to June we can see them in flower as early as late February.
This is a quite inconspicuous little plant and as such it seems to have escaped attention on the Internet and I cannot find any interesting facts about it!
