This succulent shrub is occasionally found on coastal strands in the central and southern peninsula of Florida. This non-native has escaped from cultivation and is a problem invasive. Native from East Africa, through India and Southeast Asia into Australia and the Pacific Islands.
It can be differentiated from the native species which has similar flowers by the caylx lobes being longer than 1mm (~1/32 in.) and all flowers and fruit being on pedicels. In Scaevola plumieri has very short calyx lobes 1mm or less and the center flower is sessile.
There are two varieties of the non-native half-flower, var. sericea has silky plant hairs (is sericeous) on the stem and leaves. The other variety, taccada has glabrous (smooth) or glabrate (nearly smooth) stems and leaves. These two varieties used to be considered separate species but are now widely considered the same species, although sources disagree on which species name should apply.
