PeeGee Hydrangea (Hydrangea paniculata 'Grandiflora') has a robust growth habit and impressive blooms which has made it a popular and notable staple in North American gardens.

The PeeGee Hydrangea blooms profusely from midsummer developing huge conically shaped, flower clusters that reach up to 18 in in length. The flowers start out white, and then take on a pink shade before turning beige in autumn.

Not only are the flowers strikingly beautiful but they also harbor a delightful fragrance which is very attractive to pollinators. As cold weather approaches in the autumn, the flowering season ceases and the leaves begin to senesce.

Predominately consisting of densely packed sterile flowers, each cluster is long lasting, enduring for several weeks. Because of their lasting beauty, they make great cut flowers for bouquets to brighten your home or to give to loved ones.

Landscape Uses and Maintenance - PeeGee Hydrangea (Hydrangea Paniculata)

It is an easy-to-grow shrub and maintains a vase-like shape without pruning. It prefers part shade to full sun locations, with ideal blooming in areas that receive at least six hours of sunlight per day. In warm climates, afternoon shade will help maintain soil moisture.

It is a sturdy plant and the flower clusters are easily held up during nasty weather ensuring that your garden remains a beautiful standard regardless of the climatic conditions. For best flower production, prune in late winter by cutting back the year’s growth by 12-18 in.

It prefers well-drained, neutral to acidic, loamy soils with some organic matter. Add mulch annually to help maintain moisture around this plant’s shallow roots. Soil pH will not change the color of the flower clusters as is the case with some other hydrangeas. In humid conditions, aphids, powdery mildew and spider mites can be an issue, however it tolerates cold weather and high heat conditions.

How to Grow and Care for Bare Root Shrubs

Bare root shrubs are a budget-friendly and efficient way to plant during the cooler months when they’re dormant. Before planting, soak the roots in water for 3–6 hours to rehydrate them. Choose a site with the appropriate light exposure for the species—most flowering shrubs prefer full to partial sun. Dig a hole wide enough to spread out the roots and deep enough so the crown (where the roots meet the stems) sits level with the soil surface.

Mound a bit of soil at the bottom of the hole, spread the roots over it, and backfill with native soil while gently firming it to remove air pockets. Water deeply after planting to settle the roots. Keep the soil moist but not soggy during the first growing season to encourage healthy establishment.

Mulch around the base (not touching the stems) to retain moisture and suppress weeds. Prune lightly to remove any broken branches and to shape after the first flush of growth. With minimal care, bare root shrubs will leaf out beautifully and grow into reliable, long-term landscape anchors.
