Tea Tree Introduction

Longjing 43 is a nationally recognized tea clone developed by the Institute of Tea Research, Chinese Academy of Agricultural Sciences. It features shrub-like growth, medium-sized leaves, and early budding characteristics. This variety exhibits strong disease resistance and adapts well to a wide range of growing areas.
