Camellias hold a significant place in world history and culture, and Royal Sydney Botanic Gardens is no exception. By planting the first Camellia in Australia over 200 years ago, RBGS begun a journey of collecting, displaying and now conserving, that continues today.
Recent changes to Australia’s strict biosecurity measures have now blocked importation of Camellias due to concerns over pathogens like Camellia petal blight (Ciborinia camelliae). While these restrictions are vital for protecting local flora, they challenge efforts to maintain and expand camellia genetic diversity. Additionally, the decline of backyard gardens and changing societal priorities have also led to decreased public interest in camellias and traditional gardening.
In response, the Botanic Gardens of Sydney has partnered with the Camellia Ark conservation group to curate rare species and historically significant camellias for preservation and public display. This collection serves as a living repository to safeguard these plants for future generations against the threat of Ciborinia camelliae.
Conservation efforts include:
1. Sending trained horticulturalists nationwide and internationally to research, collect, and propagate target species.
2. Trialling and implementing complex propagation methods.
3. Installing a curious new landscape to allow camellia species to flourish while paying homage to their deep Asian cultural heritage.
Through conservation efforts, botanical expertise, and innovative design, the Botanic Gardens of Sydney is positioned to secure the future of camellias in Australia, fostering public engagement, safeguarding against diseases and ensuring these plants remain an inspiring part of the nation's horticulture.
