We have a few native dropworts, generally preferring a damp spot. Otherwise they tend to have hollow stems and typical umbellifer-like flowers of white or green.
As with all umbellifers, the heads of numerous small flowers provide a huge resource of nectar and pollen for a wide range of insects from tiny pollen-beetles to large hoverflies. There are also a number of micromoths whose caterpillars feed upon the leaves or seeds.
