Saving Hibiscus Seeds

[kayrobbins]

I am growing Luna White dinner plate hibiscus plants. I love the plant because it only gets 18 inches tall, has huge blooms and is perennial. I wanted to save seeds but am not having any success. Each flower only has one large seed. From what I had read you should soak the seeds overnight before planting. When I did by morning it was just a mushy mess and did not germinate. I hope someone has experience saving these type of seeds.
