About Wild Yellow Dragon Apple Cactus

A shrubby cactus with an erect lower trunk and spreading branches. Short spines near shoot tips do not overlap adjacent areoles; longer crowded spines occur near the base. Large elongated flowers have green tubes with broad green scales, sometimes red-tipped. Immature green fruits are bumpy; mature yellow fruits become smooth. Established wild occurrence warrants observations of occupied cover, reproductive plants and new recruits. These measurements can test persistence and spread. The reviewed accounts do not quantify an island-wide effect on Kauaʻi native vegetation.
