    Landscapes, naturalizing, hedges, perennial gardens. Also makes a very dramatic cut flower.

    Maintenance Notes: 

    For the biggest, most abundant blooms and strongest stems, plant where it gets at least six hours of sun each day (warmer climates can get away with a bit less). A good layer of shredded bark mulch helps minimize water loss.

    As for pruning, cut the entire plant back by about one-third its total height each spring, just as the new growth begins to emerge on stems. This serves to build up a strong, supportive, woody base while also encouraging abundant new growth for plenty of flowers. 

    If you wish to fertilize, an application of a rose fertilizer in early spring, once the soil has thawed, is sufficient.

    • I planted these in July 2016, zone 5b. They are on the north side of my home and thus do not get as much sun as I think they want. Despite that, they have grown quite large, about 5 ft tall and have bloomed well, large and prolific blooms. My dissatisfaction is with the color. I chose these because I wanted white hydrangeas. While they do bloom white, I think the blooms are white for about 2 weeks, maybe 3 before aging to a lime green and then they stay green for a long time. Is this caused by not getting enough sun or is this just how the plant performs? I can tell mine are stretching toward the sun and they do lean forward and droop with the weight of the blooms. I have followed PW's recommendation to prune down about 1/3 of the plant in the early spring. I am wondering if I prune harder if this will help size control and perhaps help with stronger stems. I"m also wondering if I were to move them to a sunnier location if they would stay white longer. PW - what hydrangeas have white blooms the longest? What hydrangeas tolerate the most shade? Thanks!

      Satisfactory Average performance, met expectations but not outstanding.
    • I purchased this plant in August 2011 and planted it on the east side of my home. It receives no direct morning light, but there is reflected light off of my home in the a.m. and an hour or so of hot sun in the summer, but only on the top of the plant. It blooms profusely with more blooms each year! It’s approximately 6’ tall and 8’ wide. It’s easily the most beautiful flowering shrub I’ve ever grown!!

    • I planted 3 of these plants 6+ years ago. All grew notably each year and hit full size in about 3 years. The ones in full sun are very sensitive to water but doing better if you add a lot of mulch. None have ever bloomed anywhere close to the size advertised. Maybe 3-4”, relatively flat, not like a ball or giant like shown. Not the impressive look I hoped, especially for the price.

    • I ordered this in the one quart 3 years ago. The plants looked great and alive ready to plant when they were delivered. I'm in zone 5 with very alkaline and clay soil. They have done okay. The plant has grown but very slowly. (maybe 2 inches a year) I don't know how fast growing they are. They have been blooming well but the plant seems a bit week, but I'm going to chalk this up to being a young plant. Overall very good plant. Especially with how cold, hot, and dry we have here. The plants are about a little over 2 feet tall now so I'm hoping for an even better show this year.

    • Ordered a 1 qt. incredible hydrangea and planted it last fall. Extremely harsh winter (very cold) and it has already came back larger than it was when i bought it. I order 4 3 gal. and am looking forward to planting them.

      Above Average Superior performance, among my favorites, would recommend to others.
    • I have many hydrangeas around my yard and planted this one last year in spring. It initially did beautifully and bloomed gorgeous flowers in summer.. Then we had a couple days of heavy rain. I wasn't concerned because it is supposed to tolerate most areas. However with the clay soil we have in northern IL, the roots must have gotten waterlogged and the entire plant died. I was so disappointed. The rest of my hydrangeas were not affected.

    • Last year was my first planting. My tiny plants produced gorgeous blooms. I planted 4 good quality hydrangea plants. 3 stayed healthy and prolific, one started yellowing leaves and dropped leaves before its time. I know it will be replaced in spring if it does not start to grow happily on its own.
