Bomarea multiflora, the trailing lily, is a species of flowering plant in the alstroemeria family. It is a multi-stemmed vine native to Colombia and Ecuador. It is an invasive plant species in New Zealand.
Bomarea is a tuberous member of the the family Alstroemeriaceae. There are about 100 species, some of which are non-climbing, growing more like a ground cover, although the majority are climbers. They are found from Mexico on South, through the tropics and into the Andes, down to Southern Chile, and are mostly plants of the forest understory, where they grow through adjacent vegetation in lightly shaded conditions. Bomarea multiflora is a twining herbaceous climber to 3m, with narrowly oblong leaves and, from late spring, terminal umbels of orange and yellow, tubular or funnel-shaped flowers 4cm in length, spotted with brown within. It can be grown outdoors in a sheltered spot in temperate zones, but does not tolerate being frozen. Alternatively it can be grown under glass.
