saw these structures at a farm at sungei tengah. in fact, quite a number of farms that grow food crops are cashing in on the popularity of this fruit. the red variety seems to be the preferred one. do not have the idea that you can get them cheaper from these farms. the one at lane 4 lim chu kang sells it at s$4.00/kilo - used to be $5 - but their produce is bigger and juicier compared to those from vietnam. i find the fruit quite bland, more like a kiwi fruit, but some people say that it is tasty.
i was surprised when i learnt that the dragon fruit came from a climbing cactus vine. i first saw them when i visited kok fah technology farm at sungei tengah end. subsequently, i saw many more when i visited my wife's relatives in kluang, johor. in malaysia, many families grow this plant in their own garden. the flowers are white and large. they produce a nice smell when they are in bloom, which is for one night only.
