Those may be what your family calls forget-me-not, SG, but they're not. Forget-me-nots have five petals
http://en.wikipedia.org/wiki/Forget-me-not. Bizarrely, they are actually the same plant and have the same name US/UK. I know, I spend 85% of my time on here telling all y'all that it's different and that's due to top management, but this one time it
is the same. As are snowdrops, tulips, crocus and hyacinths.
Those are little wild flowers my mum would've called
Vetch (family joke, she called all small purple/blue wild flowers vetch
)
Your new contenders either are real forget-me-nots,, or my inital thought- a plant I remember , but not sure I ever knew the name. They get a lot of
cuckoo spit on them - a bubbly fluid made by insects who like that plant to protect their nests
