  1. Jerry - May 08, 2015
    Oklahoma (Hardiness Zone: 7)

    This plant arrived in perfect condition! It has thrived where it is planted. Many blooms this Spring.

  2. Martha - May 14, 2016
    North Carolina (Hardiness Zone: 6)

    Twice as full and more heathy than same plant I purchased elsewhere

  3. D.S. - May 03, 2020
    Utah (Hardiness Zone: 6)

    I've purchased hydrangeas from every major online retailer that sells them over the years. Of the countless hydrangeas I've purchased, this 7 gallon hydrangea came in the most amazing condition considering its enormous size. Packaging is #1 of all. Not a single broken branch and no stress on the shape of the plant. Even after being on its side through the shipping processes to the other end of the country! I couldn't recommend a better retailer for buying your hydrangeas. Other sources I've bought from such as the the planting tree will regularly have 30-80% of branches broken off. You want a solid plant with blooms this year? Buy from Sooner Plant Farm! Avoid the disappointment and waiting for next years blooms on a rehabilitating plant. It's worth it!

NANTUCKET BLUE™ HYDRANGEA Homeowner Growing & Maintenance Tips

Hydrangea is easy to grow and adapts to most conditions. Feed once a year with a slow release fertilizer.


Blooms will be blue colored in acid type soils and pink in alkaline soils. Change the color by simply adding Aluminum sulfide to the soil.
