White clover is the most important source of nectar in New Zealand. It is also one of the most widespread and valuable pasture plants. Honey from this nectar is white, mild flavoured, and very popular. Important native trees which supply nectar are manuka, the southern and northern ratas, the pohutukawa, and the rewarewa or native honeysuckle. Some introduced weeds (dandelion, Scotch thistle, pennyroyal, and blackberry) are also sources of nectar.
