First, this place is not located in Palawan but in Tiaong, Quezon. It's a 3-hour drive from Manila. If you are looking for a place to buy a lot of fruit bearing, flowering and ornamental plants at a low price, this is the place. They also sell rabbits as pet or as meat (Php150 for a small one) and pigs, bottles of vinegar and achara.
We bought mango plants at 50 pesos per pot, height is about 4 feet and may bear fruits after 4 years. We also bought rambutan, plants relative to birds of paradise (i don't know the name but do check out my photos), and the flowering plant, Mr. Lee (which i think they call white flower or kamuning. A cross breed between sampaguita and rosal and smells really good).
Staff are friendly and helpful. Lunch is by reservation (though we didn't try). Call ahead.
