Sophora tetraptera, widely known as Large-leaved Kōwhai, is a striking, medium-sized tree native to New Zealand's North Island. Celebrated for its vibrant, golden-yellow, bell-shaped flowers, this species flourishes in early summer, offering a visual feast and serving as a vital nectar source for birds and bees. Standing up to 50 ft tall, Large-leaved Kōwhai is distinct with its elongated, widely spaced leaflets, setting it apart from other kōwhai species. Its appeal extends beyond beauty, hosting the native longhorn beetle Coptomma variegatum, underscoring its ecological significance.

Primarily found from East Cape to the Wairarapa, and occasionally west to Lake Taupō, Sophora tetraptera thrives in moist, coastal, and lowland environments, particularly near rivers and lakes. This semi-deciduous, frost-tender species thrives in sunny locales with regular watering, showcasing remarkable drought tolerance once established. As New Zealand's national flower, it embodies the country's unique botanical legacy, making it an exquisite addition to any garden wishing to reflect Aotearoa's natural splendor.
