Pōhutukawa Bark (Medicinal Tea)
beverage
Pōhutukawa, also known as the New Zealand Christmas tree, or iron tree, is a coastal evergreen tree in the myrtle family, Myrtaceae, that produces a brilliant display of red flowers, each consisting of a mass of stamens. The pōhutukawa is one of twelve Metrosideros species endemic to New Zealand. Renowned for its vibrant colour and its ability to survive even perched on rocky, precarious cliffs, it has found an important place in New Zealand culture for its strength and beauty, and is regarded as a chiefly tree by Māori.
