Name: Glen Ingram Macleay Is, Qld, Australia (Zone 12a) (Lee Reinke X Rose F Kennedy) X Unk
This is a native I grow. Its flowers are large and gracefully wafting: Hibiscus splendens. Self seeds excellently. I have just potted 8 for a plant sale to raise money for our island library.
They are producing excellent cultivars from it now.
