'clocks'...

...like these always yell 'Dandelion' when I see them.
However not so!
These are false dandelions, cat's ears or flatweeds and are considered an environmental weed and dangerous to horses should they nibble on them.

Thankfully no horses pass this way but Astro and his fellow canine walkers love to wee on them!...so were there horses I doubt they would be interested.
