New plant varieties added to Australia exhibition at Eden Project

Catherine Cutler, the Eden Project's head of horticulture, said the masquerade variety features iridescent teal-blue flowers which were an uncommon colour in horticulture and were "highly sought".

The other new varieties are Aussie spirit with its green-yellow colour combination, the crimson pink bush crystal, the bright yellow bush zest and carnivale which has purple and pink flowers.

Ms Cutler said the new additions offered the opportunity "to see these wonderful cultivars for the first time in the UK" and "help us tell the story of how important biodiversity is in Western Australia".
