Limeberry is a shrub native to vine-thickets and rainforests in northern Australia, and a member of the citrus family Rutaceae.
Its leaves are food for caterpillars of several species of swallowtail butterfly, and the flowers attract butterflies as well – two good reasons to plant three specimens in my backyard.
In less than a year from planting, they have achieved both ends.
It remains to be seen whether it will survive the occasional frost that we get with elevation even in the tropics – it survived last winter but there were no frosts.
