Yes, Aristolochia macrophylla is fully hardy throughout the UK (RHS H5) and copes with hard frosts down to around -15C once established. It is deciduous, so it naturally drops its leaves in autumn and reshoots from the woody framework each spring with no winter protection needed.

Give it a sturdy support such as a pergola, trellis, arch or wire-trained fence in sun or partial shade. It is one of the few large climbers that performs well on a north, east or west-facing wall, where its big overlapping leaves quickly create a dense green screen.

It is a vigorous woody twiner that can reach 8-10 m in height and 3-4 m across over time, typically taking five to ten years to reach full size. Annual pruning easily keeps it to the space you have.

Yes, it is deciduous. The large heart-shaped leaves turn yellowish and fall in autumn, revealing the twining stems, then a fresh canopy of foliage emerges again from late spring.

Yes, all parts contain aristolochic acid and are toxic if eaten by people, cats, dogs or livestock, so site it away from grazing animals and curious pets. Wear gloves and wash your hands after pruning or handling the plant.
