Parsonsia heterophylla (Kaihua, New Zealand Jasmine) thrives in moist, well-drained soils that are rich in organic matter, but it is adaptable to a range of soil types, including sandy and loamy soils. For best results, plant in full sun to partial shade—full sun encourages vigorous flowering and dense foliage, while partial shade is suitable in hotter regions. Water regularly during establishment and in dry periods, as consistent moisture supports healthy growth, but avoid waterlogged conditions, which can cause root rot. Mulch around the base to retain soil moisture and suppress weeds. This climber is moderately tolerant of salt and wind, making it suitable for sheltered coastal gardens, but protect young plants from severe frost. Provide a sturdy support, such as a trellis, fence, or tree, for the vine to climb. Prune after flowering to control size, remove dead or tangled stems, and encourage bushier growth. Fertilize lightly in spring with a balanced, slow-release fertilizer to promote lush foliage and abundant blooms. With minimal care, Parsonsia heterophylla will reward you with fragrant flowers and attractive foliage, making it a standout in native gardens, forest edges, or as a feature climber.
