Growing Zones 4-9
Nature Hills is proud to present this beautiful RED Hydrangea! Grateful Red® Hydrangea (Hydrangea macrophylla 'McKRed') is an introduction from Wisconsin's McKay Nursery. It has all of the characteristics of your favorite garden Hydrangeas - big leaves and even bigger blooms coming all summer long. It will even bloom well in partial shade.
Growing into an upright oval 3-4 foot mature height and 2-3 feet width and filling out with handsome, textured green foliage with delightful toothy edges. Having the strongest stems in full sun, you'll enjoy the mophead blooms that form into scarlet red balls of smaller 4-petaled blossoms that pollinators adore! These deciduous woody shrubs are low maintenance and very easy to care for! A single bloom can fill out your entire vase and brighten bouquets as thrillers and focal points!
Grateful Red® is very brilliantly colored red in regular neutral pH and at a lower pH, you will get lavender flowers. With alkaline soils, the flowers are a deep pink verging on red that is unlike any other Hydrangea on the market. As autumn approaches the flowers turn a velvety lavender color that is eye-catching with the purple tint of the leaves. In acidic soils, the flower will be of a darker purple color.
Planting and Application:
The Grateful Red® Hydrangea will be the star of the sunnier or part shade area in your yard. Plant it where you can enjoy its unique coloration often as you walk by it. Make sure that you can reach it to cut the red blooms, too, because it will provide you with armfuls of flowers for your vases all season.
The unique red flowers will blend well with white, blues, and yellows in your landscape. This plant will receive a lot of attention and make a perfect focal point. The east side of a home is the absolute best... protection from afternoon heat but even in full sun as long as you keep it watered it will do beautifully in most parts of the country! Use as great foundation plantings and highlights throughout the landscape!

#ProPlantTips for Care:
Flowering the best and growing the strongest growth in full sun and partial shade, favoring morning sun and afternoon shade in the hottest of the USDA growing zones 4-9. Plant Hydrangea in moderate, and consistent moisture and enriched organic soil. Bigleaf Hydrangea blooms on new wood and almost all stems have a flower which is the amazing thing about this plant! Wait to see if any pruning needs to be done, then only remove any dead branch tips and only trim to remove the old flower heads as they begin to grow in spring. As the plants age, it is best to remove a few of the oldest fattest canes out to the ground leaving in some younger stems for best bloom. Old blooms can be removed in fall or spring.
- Full Sun & Partial Shade
- Moderately Moist Enriched Soil
- Highly Adaptable
- Prune Bigleaf Hydrangea After Flowering
