Hydrangeas are a gorgeous addition to your yard with large blooms that appear after early bloomers (eg: lilacs) are done.
Pinky Winky flowers start white but quickly develop contrasting pink petals and ultimately, a deeper pink!  
These really stand out! 
Plant in part sun/part shade.  In warm areas of your yard, plant with some morning sun and shade during the hottest part of the day.
2 gallon pot size.
 
Zone 3, matures to 5-6 feet tall and wide .
