Most of the dense bluegum eucalyptus stands in California and Hawaii are noted for being almost devoid of understory vegetation, except for a few hardy grasses. Although this condition is most likely related to the rather dry climate that provides the best site for the species, it has also been shown that the leaves of the tree produce water soluble phytotoxins that can prevent radicle growth of many herbaceous plants (7). In Hawaii, firetree (Myrica faya) is a species that sometimes invades bluegum eucalyptus stands. The noxious passion fruit vine (Passiflora mollissima) has also been found thriving in a young coppice stand.
