This week’s flowering Friday is Hibiscus insularis, commonly known as the Philip Island Hibiscus. The stunning flowers on this large, dense shrub first open cream coloured, but fade to a soft rose pink the day after they open. New flowers will continue to bloom over many weeks. Critically Endangered, Hibiscus insularis only occurs naturally on a single small island just off Norfolk Island, but fortunately it grows well in Melbourne’s climate. Hibiscus insularis enjoys full sun and good soil, and is both drought and frost tolerant. It makes for a fantastic screening plant with only light pruning. You can find this beauty growing in the Ian Potter Lakeside Precinct at Cranbourne Gardens.
