Hydrangeas

 Two very ordinary garden plants
mop head hydrangea
 (Hydrangea macrophylla) 
& common yarrow

 (Achillea millefolium)

looking delightful together

Hydrangea serrata 'Beni Gaku' under the Oak Tree

Close up of Beni after the rain

The Oak Leaf (Hydrangea quercifolia)
starting to change color
after pink they turn to buff
 in the fall their leaves will be red & purple
What a great plant!
