Guide

The species-level account. Cultivar pages build on this and say where they differ.

Polyscias guilfoylei is a tropical island shrub to small tree from the Bismarck Archipelago, New Guinea, Vanuatu and nearby Pacific islands. It wants warmth and bright indirect light, with steady but never soggy moisture; its woody habit and tropical origin mean it dislikes both drought and standing water. Water when the top inch or two of mix has dried, and let excess drain freely.
