Educating Stevvi.

This could come as a shock but not all yellow flowers are either dandelions, buttercups or daffodils.  I searched the whole allotment to find the only dandelion on site.  The other shots show neighbouring ones gone to seed.  
To further your education I would guess you would name the red flower as a poppy when in fact it is another nasturtium - see yesterday's silly mistake by you.
