Rosa 'Crescendo', (aka JACgemze ), is a pink and white hybrid tea rose cultivar, bred by Dr. Keith Zary in 2010, and introduced in the United States by Jackson & Perkins in 2011. The rose was created from stock parents, Rosa 'Gemini' and Rosa 'New Zealand.[1] 'Crescendo' was awarded the prestigious Portland Gold Medal in 2019.
'Crescendo' is a tall, upright shrub, 5 to 6 ft (152—182 cm) in height with a 3 to 4 ft (90—121 cm) spread. Blooms are large, 4—5 in (10—12 cm) in diameter, with 26 to 40 petals. Buds are pointed and ovoid. Flowers have a very full, high-centered bloom form, and are borne mostly solitary. The flowers are a pink blend, and are generally creamy white with light pink hues, and darker pink edges.[2] The rose has a strong fragrance and large, glossy, dark green foliage. 'Crescendo' blooms in flushes throughout its growing season. The plant is recommended for USDA zone 5 and warmer.[3]
