Hue City is the urban area with the highest density of trees in the country, with more than 64,000 trees lining its streets, parks, and lush green garden houses. These trees are cared for and protected by both local authorities and residents, beautifying the city while serving as a natural shield that brings a refreshing sense of coolness during the scorching summer heat.

At the end of the academic year, when flamboyant trees begin to burst into fiery red blossoms, yearbook photography services also enter their busiest season, allowing students preserve their school memories.

In March, as late spring draws to a close and gives way to the first heat of early summer, the parasol trees in the Imperial Palace burst into bloom. Their canopies of soft pink-purple flowers, scattered across an ancient expanse of deep green, create a poetic and dreamlike landscape that captivates all who visit.

Many journeys back to old Hue begin with seemingly small details. For me, it was a visit to An Thu garden house in Gia Hoi old quarter - a contemplative Hue residence nestled behind lush green trees. Mr. Vo Chanh Tien, the current caretaker, led me through the rooms while sharing the house's history and stories of generations tied to the garden and the rhythm of the old Gia Hoi. But what made me linger the longest was actually… beneath my feet.

Hue City has recently launched the digitalization of its urban trees. Information on location, species, and health condition of each tree is now updated in data, paving the way for a more scientific, proactive, and safer approach to managing a heritage city.

Alongside their efforts to help trees sprout and flowers bloom across the nation’s borderlands, the Border Guard force has been nurturing a vibrant spring in the hearts of the people.

That is the vast green casuarina forest that the people of Thai Duong Thuong village (formerly Hai Duong Commune, now part of Thuan An Ward, Hue City) planted decades ago to shield them from the winds, stop the sand, and protect the village. Amidst the vast sky and land, the casuarina trees grow lush and strong, becoming a sturdy shield, guarding the village from waves and winds, and the harshness of the sea.

Alongside preservation of palaces and temples, the heritage conservation efforts in the Ancient Capital also include the care, restoration, and propagation of trees, protecting ancient and precious species within relic sites, helping maintain the harmonious beauty of architecture and nature - a hallmark of Hue’s heritage space.

I visited Dang Mau Tuu’s Song Nhu Gallery many times and realize that he paints a lot about Hue gardens. Each of his paintings tells a story about trees, people, and “fragrant” silences.

The lush lawns and shaded canopies of ancient trees in the Imperial Citadel, Co Ha Garden, or Thieu Phuong Garden are not naturally self-sustained. Behind that serene beauty lies the quiet dedication of dozens of workers who care daily for every tree and flowerbed, helping preserve the “green soul” of Hue’s heritage.

The Firmiana simplex flower is a unique one of Hue, with its dreamy shades of pink and purple colors. According to historical records, Emperor Minh Mang was so fond of the flower that he brought it to plant beside Can Chanh Palace and some corners of other palaces.

On cold winter days, the red Sau Sau leaves fall, leaving bare branches. At this time, the Sau Sau forest evokes a sense of wandering into unfamiliar lands.
