SEA ANEMONE PASSION FLOWER - Biosecurity
SEA ANEMONE PASSION FLOWER
The threat: Sea anemone passion flower is a potential threat to New Zealand’s environment with its ability to smother and
shade the vegetation it grows on.
Why is sea anemone passion flower a pest?

Sea anemone passion flower (Passiflora actinia) readily climbs
trellises, garden fences and other plants. Once mature, it is
able to withstand frost. These invasive characteristics show
the plant’s potential to impact upon native, flora, fauna and
ecosystems.
Where is it found?
Sea anemone passion flower has been found growing at
Helensville, Auckland but has the potential to also grow in
Northland, Bay of Plenty, Hawkes Bay, Coromandel and other
warmer areas of the country.

The sea anemone passion flower is a fast growing, evergreen
perennial vine native to Brazil. It grows in part-shade and
thrives in moist environments with bright but indirect sunlight.
What does sea anemone passion flower look like?
Flowers (4–8cm diameter) are attractive with bluish purple
and white bands giving a “speckled” appearance. These are
followed by edible yellow/orange round hairless fruits (3–4cm
diameter). The leaves are oval shaped (1.5–3.5cm long).

Could I mistake other plants as sea
anemone passion flower?
Flowers of the sea anemone passion flower are similar to both
those of the blue passion flower (Passiflora caerulea) and the
purple passionfruit (Passiflora edulis), both of which are found
in New Zealand.
Blue passion flower is well established in New Zealand and
purple passionfruit is commonly grown by plant enthusiasts for
its edible fruit.
