It is pollinated in the northern part of its range by the specialist oil bee "Macropis nuda", a native bee species whose survival depends upon this host plant.It is also cultivated as an ornamental plant. It can be aggressive, but new suckers can be removed easily to keep plant size under control. The most common cultivars of "L. ciliata" include:
