3 types of Dragon Fruits: - RED Dragon Fruit (aka pitaya or pitahaya or strawberry pear) were those with RED SKIN and WHITE FLESH (Hylocereus undatus). It tasted a bit bitter to me and I didn’t like the after-taste. Other reports said it tastes like a mix of kiwi fruit and watermelon. - RED SKIN Dragon Fruit with RED FLESH (Hylocereus polyrhizus) variation. - YELLOW SKIN (Selenicereus megalanthus) and with only white flesh.
