Dianella, WA
By Lauren McCaleb · Reviewed by Dylan Duncan ·
Dianella is a suburb of Perth in the City of Stirling, north-east of the city centre. It takes its name from Dianella revoluta, a small blue-flowered lily that grew across the area before the houses came. Early growth was slow: the sandy soils of the Banksia sandplain were thought poor for farming, and into the early 20th century the only real development followed Walter Road out to the dairy farms around Morley. Several older localities — North Inglewood, East Yokine, Morley Park and Bedford Park among them — were brought together under the name Dianella in 1958, and suburban housing spread through the 1960s, ranging from modest post-war homes to large modern dwellings. For decades Dianella was the centre of Perth's commercial television industry, hosting several of the city's stations until they moved away in the 2010s. It is also home to long-established Jewish and Greek communities, reflected in its schools, churches and street names.
