(Tigard, Oregon) My baby thrived in my new flower beds. She gave me many many blooms, and even though she bloomed pure white, her blooms changed to a greenish/purple color when the flower matured. Full sun, but we found that her leaves take to looking as if she has a blight if she gets water on her leaves. Otherwise, a GORGEOUS addition to our sanctuary.
Doesn't do well in central MS. Easy to grow from cuttings just stuck into the ground. Just doesn't want to bloom for me no matter what, and I've given it 3-4 years and plenty of sun. Don't kow if it is the heat or what, but I've read elsewhere that it is a cooler-weather plant.

A wonderful shrub (or tree depending on how it's grown) that is easy to care for and keeps on giving back!. I have ours planted in moist locations in semi-shade. Blooms on "old" wood. Do not prune back except when you are cutting blooms for arrangements in early fall - if you prune in spring you will remove all the flower buds that would blossom in fall.
I have added several PG hydrangeas to my garden so that I may use the blooms in dried arrangements. Here in zone 5, this particular hydrangea comes into bloom in August and is ready for harvesting of the blooms in mid to late September - after they have changed from white to a rosy color with green undertones. They make wonderful arrangements to put in a vase and enjoy all winter long! To dry, simply cut when the blooms have taken on the colors above and feel a bit "papery" to the touch, then arrange in a vase. No need to add water. Just make sure you cut the stems long enough to suit what you're doing.

A deciduous shrub commonly referred to as "peegee" in reference to its name, H. paniculata produces flowers in erect panicles 3-10" tall. Blooms in early summer, flowers are initially white, aging to pink then to rust in autumn. The flowers can be used in dried arrangements.
Unlike H. macrophylla, soil pH will not affect color of blooms. Plant in well-drained average garden soil.
Peegee hydrangea blooms on new growth, so pruning should be done in late winter or early spring.
