Highways and Byways: Barking up the right tree in Gaofeng Botanical Gardens

The 16-hectare garden located a stone’s throw away from Hsinchu’s National Tsing Hua University was established in 1932 by the Japanese colonial authorities and boasts 150-plus tree species

I was beginning to wonder if Mother Nature had it in for me. For the second time in less than 10 minutes, a gust of wind dislodged a branch from the canopy, and it clattered down right where I’d been standing a few moments earlier.

Hsinchu is famously windy, and I was in Gaofeng Botanical Garden (高峰植物園) on an exceptionally blowy winter’s day. Each time the sun came out, clouds maneuvered to obscure it within seconds. Stands of bamboo pitched like galleons rounding Cape Horn. The nonstop clattering reminded me of kendo training sessions.

I’d entered the garden from Baoshan Road (寶山路), 650m west of the southern entrance to National Tsing Hua University (國立清華大學). There’s another entrance at the end of Lane 160, Gaocui Road (高翠路160巷). From the latter, follow the gravel path until you reach a gazebo equipped with a drinking-water machine. From there, you can continue straight ahead, or turn right and go anticlockwise around the 16-hectare garden.

My own clockwise 90-minute hike through Gaofeng Botanical Garden had begun at the pedestrian bridge which crosses Baoshan Road, linking the garden with the often-crowded hiking area known as Eighteen Peaks Mountain (十八尖山). Given the speed and quantity of traffic on the road, this bridge has undoubtedly saved lives.

Following a path beside a tiny creek, I snapped some pictures of a colorful butterfly, not knowing it would be one of the very few insects I’d see during my early-afternoon hike. It wasn’t just the wind; surely the cold was another reason why I saw hardly any birds or lizards.

In the absence of moving creatures, including other humans, I decided to focus on the trees, especially their different barks. Established in 1932 by the Japanese colonial authorities then controlling Taiwan as a tree nursery to supply seedlings to experimental forests, Gaofeng Botanical Garden is a good place to do this. It’s now home to an impressive 150-plus tree species, many of which are labeled with their Chinese and scientific names.

The first tree I paid close attention to was a waist-high specimen of Sapindus mukorossi, known in different parts of Asia as Indian soapberry or Chinese soapberry.

In the rural Taiwan of yesteryear, soap made from its seeds was used not just to do laundry, but also for washing hair; chemicals in the seeds help remove head lice. More recently, scientists have discovered that the seeds can be used to make both biodiesel and a surfactant (a compound lowering surface tension) which could help extract oil from existing reserves by increasing the oil’s mobility.

A section of trail in the heart of the botanical garden has been dubbed the Formosan Sweetgum Roadway (楓香景觀步道). It’s lined with Liquidambar formosana trees, the leaves of which display delightful shades of red, orange and yellow during the autumn. Despite its name, this species isn’t endemic to Taiwan, growing as far away as Laos.

Such is the density of trees and other foliage that at only one spot was I able to see the office blocks and apartment buildings of Hsinchu.

In terms of their barks, two of the most interesting trees inside the garden were a slash pine (Pinus elliottii) and a lemon-scented gum (Corymbia citriodora). The former is native to the southeastern US; the latter comes from the northeast of Australia.

The slash pine is so named not for its craggy, scabrous bark — which looks as though an angry person took an axe to it — but rather because it grows best in the swamplands colloquially known as “slashes.” It was once used to produce resin and turpentine.
