Honeybush (Cyclopia) species are endemic to the Fynbos Biome of the Cape Floral Kingdom in South Africa. Traditionally, honeybush foliage is cut, fermented, and sun-dried to make an antioxidant-rich herbal tea. Approximately 80% of honeybush is unsustainably harvested from the wild. All commercial species are indicated on the International Union for Conservation of Nature Red List of Threatened Species. Cultivation is thus required to ensure sufficient volumes of tea are produced. A major limitation to cultivation is the poor rooting responses of the species that regenerate from shoots, C. genistoides and C. intermedia, the latter being the most harvested from the wild. The establishment of clonally propagated material is a challenge for all six of the commercially important Cyclopia species. Research on honeybush has mainly focused on the unique properties contributing to flavor, medicinal value, as well as processing. Much less is known about propagation, nutrient requirements, harvesting procedures, plant improvement, and pest and disease management. This review considers management strategies for the sustainable harvesting of wild honeybush and the potential risks of introducing improved plant material. Cultivation practices and management strategies that promote longevity and enhance yield are defined. The inherent rooting ability of cuttings is discussed. Cultivated stands are mostly established by seedlings which results in diversity of vigor and tea quality. A sustainable market based on high-quality indigenous tea requires the use of clonal material which allows the selection of desired traits and rapid multiplication. Its use would enable improved yield and profitability without compromising tea quality.

Honeybush (Cyclopia spp.) 的繁殖和栽培实践，用于可持续生产出口品质的南非本土茶

Honeybush ( Cyclopia ) 物种是南非开普花卉王国 Fynbos 生物群落的特有种。传统上，蜂蜜灌木的叶子被切割、发酵和晒干，制成富含抗氧化剂的凉茶。大约 80% 的蜜树是从野外以不可持续的方式收获的。所有商业物种都被列入国际自然保护联盟濒危物种红色名录。因此需要进行栽培以确保生产足够量的茶。栽培的一个主要限制是从枝条再生的物种、C. genistoides和C. intermedia的生根反应差，后者是从野外收获最多的。克隆繁殖材料的建立对所有六个具有商业重要性的独眼巨人来说都是一个挑战物种。对蜜树的研究主要集中在有助于风味、药用价值和加工的独特特性上。对繁殖、养分需求、收获程序、植物改良以及病虫害管理知之甚少。本综述考虑了可持续收获野生蜜树的管理策略以及引入改良植物材料的潜在风险。定义了促进长寿和提高产量的栽培实践和管理策略。讨论了扦插的固有生根能力。栽培林多以幼苗立植，生势和茶质参差不齐。基于优质本土茶的可持续市场需要使用克隆材料，从而可以选择所需的特征并快速繁殖。它的使用将在不影响茶叶质量的情况下提高产量和盈利能力。
