One of the most defining features of the Azorean landscape is the incredible sight of hydrangeas, or Noveloes as they’re known in Portuguese. These beautiful, vibrant flowers, scientifically named Hydrangea macrophylla, blanket the islands, lining roads, fields, and gardens with a stunning splash of color.

While the hydrangea is originally from Japan and was introduced to the Azores in the 19th century, it has become a powerful symbol of the islands. Its presence is so widespread that it’s often used to create natural fences separating pastures and properties, a testament to how perfectly it has integrated into the landscape. On Faial Island, also known as the “Blue Island,” the sheer abundance of these blue hydrangeas gives the island its nickname.

They thrive here because the Azores’ volcanic, acidic soil provides the perfect conditions for them to grow in abundance. The color of a hydrangea is a fascinating reflection of the soil it’s planted in. The more acidic the soil, the bluer the flowers become. As the soil becomes more alkaline, the flowers turn pink or even red. It’s not uncommon to see different shades on the same plant, creating a beautiful and unique display.

The hydrangea season transforms the islands throughout the year:

• April: The first blooms begin to appear, signaling the start of spring.
• June: The islands are at their most colorful. This is the peak season, when the hydrangeas are in full, brilliant bloom.
• August: As the season progresses, the flowers begin to fade, turning a soft, beautiful white.
• October: The blooms have fully faded, turning a rustic brown before they fall off, preparing the plants for the next cycle of growth.

The hydrangeas are a stunning natural spectacle and a true testament to the unique beauty of the Azores. While some local biologists consider them an invasive species that can displace native flora, there is no denying their role in shaping the iconic scenery of the islands.
