Given how many expats live in Australia it’s hardly surprising that English cottage gardens are popular down under. However, the ones I saw were owned by Australians and South Africans. My garden it’s highly influenced by the tropical plants of my birth place Jamaica however, it’s also influenced by English cottage gardens that merges informally with dense plantings.
The plant of my Australian Odyssey was the Agapanthus (African lily) that seems to grow everyone.
