Complete Plant Information
Overview
Hydrangea paniculata ‘Renhy’ VANILLA STRAWBERRY, a striking cultivar marketed as VANILLA STRAWBERRY, offers an outstanding late-season floral display in the garden. This Panicle hydrangea is prized for its vigorous, upright habit and exceptional winter hardiness, making it a reliable choice for colder regions where other hydrangeas might struggle. As one of the most winter-hardy hydrangeas, it consistently delivers blooms on new wood throughout the summer and into the fall.
The aesthetic appeal of this specific Panicle hydrangea lies in its evolving flower color. The large, conical panicles emerge white, transition through sweet pinks, and finally mature to a deep pinkish-red hue by late summer. This multicolored characteristic ensures continuous visual interest in the landscape when many other shrubs have finished flowering for the season.
This cultivar is highly adaptable, thriving almost anywhere it receives adequate moisture and protection from the harshest afternoon sun, though it performs best in full sun. Gardeners appreciate its ability to be shaped into a small tree or maintained as a dense shrub, adding structure and significant late-season color to perennial borders or as an accent specimen.

How to Grow
Hydrangea paniculata ‘Renhy’ VANILLA STRAWBERRY should be planted in the spring or fall after the danger of hard frost has passed, allowing it to establish a strong root system before extreme summer heat. Ensure the planting site offers organically rich, medium-moisture, well-drained soils. While this Panicle hydrangea can tolerate urban conditions well, proper drainage is essential to prevent root issues throughout the growing season.
Water requirements are medium; consistency is key, especially during establishment and periods of intense summer heat. Avoid letting the soil completely dry out. Pruning should be performed in late winter to early spring, as bloom occurs reliably on current season’s growth. For the best, largest panicles, thin the plant back to 5-10 strong primary shoots, which also helps manage the eventual height.
Be aware that in full bloom, the substantial weight of the flower panicles on Hydrangea paniculata ‘Renhy’ VANILLA STRAWBERRY often causes branches to arch downward, creating a lovely cascading effect. If you are aiming for a perfectly upright specimen, regular pruning to a height of 6-10 feet helps maintain a robust shrub form. This species is recognized for being one of the most winter-hardy hydrangeas available.
Landscape Uses
The use range for Hydrangea paniculata ‘Renhy’ VANILLA STRAWBERRY is extensive, making it a flexible addition to nearly any garden structure. It looks superb when massed together to form a screen or informal hedge, leveraging its medium height and dense foliage. Furthermore, this Panicle hydrangea functions beautifully as a lawn specimen, commanding attention with its massive, colorful blooms during the late summer lull.
For mixed borders, place this shrub toward the back or middle where its size can be accommodated, pairing it with late-season perennials that share its preference for sun to part shade. Its upright structure also makes it an excellent accent plant near entryways or transitions between formal and informal garden zones. Because it provides reliable bloom later than many other flowering shrubs, it bridges the gap until fall-blooming perennials take over.
The visual interest created by the color shift from vanilla white to strawberry red ensures that the Hydrangea paniculata ‘Renhy’ VANILLA STRAWBERRY anchors the landscape throughout late summer and early autumn. Consider its eventual size to prevent overcrowding neighboring plants that may require more sunlight.

Noteworthy Characteristics
Hydrangea paniculata, commonly called panicle hydrangea, is a vigorous, upright, rapid-growing, somewhat coarsely textured, deciduous shrub that is native to China and Japan. Its specific epithet paniculata refers to the arrangement of the flowers in panicles, and the cultivar ‘Renhy’, sold as VANILLA STRAWBERRY, features panicles often reaching 7” by 5” composed primarily of showy sterile flowers blooming on new growth from mid-summer to fall. The flowers are famous for opening white, changing to pink, and finally maturing to pinkish-red, offering a stunning multicolored effect from vanilla white to strawberry red late in the season before fading brown.

Potential Problems
This Panicle hydrangea is generally robust, but growers should watch for minor issues common to the species. There is some susceptibility to common issues such as leaf spot, rust, and powdery mildew, particularly in areas with poor air circulation or high humidity. Occasionally, pests like mites or aphids may appear, usually without causing severe damage. Preventing these issues starts with ensuring good air movement around the shrub and maintaining consistent soil moisture appropriate for this medium water-need plant.
To address fungal issues, ensure the plant is sited according to its cultural needs—full sun to part shade with good drainage helps dry foliage quickly after rain or irrigation. If pest pressure is high, horticultural oils or insecticidal soaps can manage aphid or mite infestations effectively without harming beneficial insects in the long run.

Companion Planting
When planning complementary plantings near your Hydrangea paniculata ‘Renhy’ VANILLA STRAWBERRY, focus on species that enjoy similar soil acidity and moisture levels. Consider pairing it with structural evergreens that provide winter contrast, such as dwarf spruces or upright junipers, against which the arching habit of the hydrangea can shine. For complementing its mid-to-late summer bloom, consider hardy perennials like Astilbe (in shadier spots) or Rudbeckia (Black-eyed Susan) for sunnier exposures.
Remember that because this cultivar can grow up to 8 feet tall, selecting shorter companions that won’t be completely overshadowed is important. Groundcovers like creeping sedum or low-growing Hostas work well at the drip line, softening the transition from lawn to shrub. The medium water needs of the VANILLA STRAWBERRY dictate that companions should also prefer consistently moist, but not waterlogged, ground conditions.
Design Ideas for Late Season Interest
Leverage the unique maturation sequence of the Hydrangea paniculata ‘Renhy’ VANILLA STRAWBERRY to create dynamic color phasing in your yard. Plant groupings of three or five to create a substantial visual impact that highlights the transition from white to pinkish-red. This shrub looks exceptional when allowed to weep naturally over retaining walls, using gravity to enhance the cascading look conferred by the heavy blooms.
To truly showcase the ‘vanilla strawberry’ color shift, use these shrubs as vertical accents against backgrounds of deep green or dark purple foliage. Dark-leaved Ninebark varieties or evergreen screens offer the perfect backdrop to make the white and pink hues pop, especially as they begin to deepen in color toward August. This plant serves as an excellent structural middle layer in a full-sun border, maturing just as many spring and early summer bloomers are fading.
