About Loosestrife
A slender, much-branched shrub with small, nearly stalkless, oblong leaves, generally opposite but sometimes alternate on fast-growing shoots. Solitary leaf-axil flowers have green tubes, purple petals and six slightly projecting stamens. Small ellipsoid capsules contain numerous tiny reddish-brown angular seeds. This native shrub is a component of Hawaiian vegetation. Monitoring mature plants, new recruits and occupied cover can assess persistence and replacement. The reviewed accounts do not establish a measured Kauaʻi population trend or quantify an ecosystem effect.
