Most gardeners want blue hydrangeas and usually buy the Nikko blue variety, then go to extra lengths to ensure they get blue with a ph balancing fertilizer. I guess it's the loam and peat moss I used, because I used nothing special.
If I were honest, I would admit I love the blue, even though I didn't think I would. The blue really sets off the pink Astilbes. Some of the Hydrangeas are multi-colored which I also think is very pretty. Also, I'll bet if I tried to duplicate this process in another bed, I'd get different results!

It just goes to show flowers are more versatile and forgiving than one would think . . . thank God.
