Parsonsia heterophylla, commonly known as New Zealand Jasmine or Kaihua, is a climbing vine that is endemic to New Zealand, where it thrives in lowland and low montane forests, particularly at forest margins, clearings, and along stream banks. It can grow up to 33 feet tall, with opposite, shiny dark green leaves that are variable in shape. The plant produces clusters of small, white, fragrant, tubular flowers during spring and summer, which are particularly attractive at night when they are pollinated by moths. The flowers’ sweet scent is a notable feature, and they are followed by long, slender seed pods. Kaihua’s nectar is also a food source for the New Zealand bellbird.

New Zealand Jasmine is valued for its ornamental appeal, with its twining habit and fragrant flowers making it a popular choice for trellises, fences, and pergolas in gardens. It is relatively easy to maintain, requiring moderate watering and thriving in well-drained soils with rich organic matter. It prefers a position in full sun to part shade. While generally disease-free, it can be susceptible to root rot if overwatered or planted in poorly drained soils. Gardeners should be aware that Parsonsia heterophylla can become quite vigorous and may require regular pruning to keep it under control.CC BY-SA 4.0
