One of the original citrus plants from which Lemons and Limes have been hybridised, the Citron, stands out as a unique specimen appreciated by collectors for its aromatic fruit and revered in Judaism and Buddhism for its religious usage. Characterised by a thick rind and large pith, Citron fruits often yield only a small portion of dry pulp, with some varieties, like the Buddha’s Hand and Etrog, exhibiting minimal pulp. Of note is the considerably variety amongst Citron species, ranging considerably in size, form and amount of pulp within. Ripe fruits exude a delightful fragrance, serving as a natural air freshener, particularly the Buddha’s Hand variety. Essential oil extracted from the fruits is utilised in perfumery. The thick rind is prized for its aromatic flavour, finding its way into beverages, desserts, and confections, often being made into Succade (candied peel) or added to fruit cakes. In Southern Italy, fruits are used to create “Cedrata”, an aromatic, citrus soft drink. The Buddha’s hand variety is a traditional temple offering in Buddhism, while the Etrog is used in the Jewish holiday of Sukkot. Similar to many other citrus fruits, Citrons are abundant in Vitamin C, as well as dietary fibre and antibacterial properties. Citron are ideally suited to warm, subtropical, coastal climates with regular rainfall and frost-free conditions, preferring to be shielded from strong winds. Citrons thrive in well-draining, slightly acidic to neutral loamy soil and greatly benefit from mulching. They are particularly vulnerable to frost, drought, and extreme heat during fruiting, exhibiting less tolerance to these conditions compared to most other citrus varieties. However, the hardy Trifoliata rootstock undoubtedly confers significant benefits to their resilience. Citrons can reach heights of up to 3-4 metres, retaining a shrub-like form that makes them well-suited for cultivation in containers. Plants feature slightly thorny branches and dense foliage with wavy margins, while their white flowers exude a beautiful fragrance. A coveted item for citrus enthusiasts and valued for its religious significance, the Citron holds a special place in both horticultural and spiritual realms.
