Flower Friday - Weeds and Seeds

Flower Friday again  - where did that week go to.

I am having a mental block as to the name of this common weed but you will probably all recognise it. Not a dandelion but has all these tiny little puffs of seed head similar to the dandelion 'clock'.  The paddock next door is full of them and so my garden will probably be full of them next year.

This one is transitioning from the yellow flower to fluffy seed head.
