Karaka
IOverview
Overview
Karaka, scientifically known as Corynocarpus spp., is a medium to large tree belonging to the Myricaceae family. Native to New Guinea and Queensland, this tree is adaptable to various soil types, including light (sandy), medium, and heavy (clay) soils, and thrives in environments with partial sun to full sun exposure. Karaka is hardy in USDA zones 7-10 and can grow up to 15 meters tall. It is valued for its edible fruit and seed, making it a useful addition to gardens and landscapes. The fruit can be eaten raw or used in various preparations, while the seed is processed to make flour or oil, but requires careful preparation to remove toxic compounds. The fruit is typically consumed fresh, while the seed must be carefully prepared to ensure the removal of toxic compounds before consumption. Karaka's ability to grow well in diverse soil conditions and its ornamental value make it a versatile plant for cultivation. However, it is important to handle the seeds with caution due to their toxic compounds.
