Heraldo de Madrid - 'Under attack' from fragrance, Hanoi prunes its famous blossoms

The Vietnamese capital boasts more than 14,400 alstonia scholaris, tall evergreens that shade the streets in summer and in autumn produce flowers that fill the air with a heady scent.

For many residents, it is too much.

"The smell is so overpowering that it becomes unpleasant, especially when the weather is hot," Hanoi resident Tran Trung Phong told AFP.

The 56-year-old said he keeps his doors and windows shut and suffers from headaches and breathing difficulties as his four-storey home comes "under direct attack" from dozens of trees nearby.

"If it were up to me, I would replace them all," he said.

His complaint is similar to those made across social networks and reported in state-run media in recent days, prompting Hanoi authorities to bring out the chainsaws.

On Friday, they began a drive to prune up to 1,000 trees along 13 streets with the aim of reducing their intense fragrance.

The trees are common across much of Asia.

In Vietnam, where they are known as "hoa sua", they are evoked in nostalgic or romantic songs and poems about Hanoi.

But a poll conducted by state-controlled online newspaper VNExpress found 80 percent of respondents supported removing or relocating the trees.

"Only those who don't live near these trees find them romantic with a pleasant fragrance," wrote Thanh Luong on Facebook.

She said her bedroom is located about 100 meters away from two trees, adding: "It's torture."

- More suitable locations -

The evergreens, which reach more than 10 metres tall, are synonymous with Hanoi -- so much so that they have been planted in central and southern Vietnam as a way to import some of the capital's charm.

For local resident Lan Huong, they are key to the city's identity, and also provide a welcome flash of nature in polluted streets.

"Hoa sua is the signature for Hanoi. Everyone knows and accepts that as a fact," she said.

"Isn't breathing in the scent of flowers far more pleasant than inhaling smokes from bikes and cars?"

In a statement on Thursday, city authorities said the smell "negatively impacts the health and daily lives of residents".

They said they will consider if they can "relocate some of these trees to more suitable locations and replace them with other types of greenery".
