Climbing rose 'Improved Blaze'
FamilyRosaceae
The Rosa 'Improved Blaze', a vigorous and intensely colored climbing rose, is renowned for its vibrant scarlet double flowers that retain their intensity throughout their bloom. Produced in generous clusters, they create a spectacular effect during the main flowering season, followed by lighter flushes throughout the rest of the season. Its classic style makes it an essential choice for adorning arches, pergolas, and facades with immediate visual impact. Lightly fragrant, it primarily captivates with its abundant blooms and reliability. Its dense, robust dark green foliage highlights the vibrancy of the red while contributing to good overall resistance. Appreciated for its vigor and sustained floriferousness, the Rosa 'Improved Blaze' brings energy, structure, and chromatic intensity to vertical landscaping while actively attracting pollinating insects.
