The Kanmara White Hydrangea macrophylla is a premium potted flowering plant sold in an 11.5-inch container, part of the next-generation Kanmara hydrangea series developed by the Hydrangea Breeders Association. This variety is prized for its large, majestic white blooms and elegant dark green foliage, making it an ideal statement plant for patios, doorsteps, balconies, and garden beds.

Kanmara hydrangeas are known for their extended blooming season, with flowers emerging in early spring and lasting through late summer and fall. The plants feature an upright growth habit and are notably shade tolerant, thriving in partial sun conditions. Mature plants reach 20–24 inches in height and 34–36 inches in width. Heavy watering and monthly fertilization support the best performance.

The Kanmara line is a registered trademark (U.S. Patent PP25,390) available in multiple colors; this Costco offering features the classic white variety in a 3.44-gallon (13.01-liter) nursery pot.
