Notes
Blue passionflower (Passiflora caerulea) is regarded as an environmental weed in Victoria and some parts of New South Wales. This species is sometimes cultivated as an ornamental, but is more often grown as a rootstock for other cultivated species of passionfruit because of its tolerance to cold and pathogens. It often sprouts from below the graft, growing rapidly and escaping cultivation. It can spread quickly in bushland areas, densely smothering native vegetation.
Blue passionflower (Passiflora caerulea) is currently of most concern in Victoria, where it is seen as a potential threat to one or more vegetation formations. It appears on some local and regional environmental weed lists in this state (e.g. in the Mornington Peninsula Shire and the Goulburn Broken Catchment). It is also regarded as being weedy in the Illawarra region on the southern coast of New South Wales.
In New Zealand, blue passionflower (Passiflora caerulea) is a weed of coastal areas, lowland shrublands and forest margins. It also invades and fills gaps in forests, climbing into the tree canopy and smothering native plants.
