True or false: Rambutan trees are closely related to lychee and longan trees.

Accepted Answer

True. All three belong to the Sapindaceae (soapberry) family, sharing similar fruit structure and growing conditions.

Question 2

True or false: Rambutan fruit turns blue when fully ripe, similar to some berries.

Accepted Answer

False. Rambutan skin ripens from green to red or yellow, never blue. The flesh is translucent white.

Question 3

True or false: Rambutan trees can grow over 80 feet tall in the wild.

Accepted Answer

True. In tropical forests, rambutan trees can reach up to 25 meters (82 feet), though cultivated trees are pruned shorter.

Question 4

True or false: Rambutan trees are self-pollinating and never need insects or wind.

Accepted Answer

False. Rambutan trees require cross-pollination, often by bees or other insects; many cultivars need a second tree for fruit set.

Question 5

True or false: Rambutan seeds are always safe to eat raw and taste like almonds.

Accepted Answer

False. Raw rambutan seeds contain toxic saponins and tannins; they must be cooked to be safe, though some cultivars are milder.

Question 6

Accepted Answer

False. Rambutan trees typically bear fruit once or twice a year, usually during the rainy season, not continuously year-round.

Accepted Answer

True. A rambutan tree in the Philippines, planted in the 1800s, reportedly continues to produce fruit, showing remarkable longevity.

Question 8

True or false: The rambutan's hairy red skin is actually a cluster of modified leaf structures.

Accepted Answer

True. Those soft spines are called spinterns—outgrowths of the skin derived from leaf tissue, not hairs.
