I have two bushes this year, bought as about 500mm high bushes from Bunnings. The site is very sandy soil on the east coast of Brisbane so I covered it with shadecloth and planted into that through a hole. I put combo fertilser pellets (chicken, cow etc)in the base of the hole. As soon as the bushes were rooting and growing I took out all the centers of the branches to make them bush, and get more flowers. They flowered in 8-10 weeks and of course the calyx was immediately available. We have picked about 2 kilos from the 2 bushes, washed and frozen them as there's plenty still to come. They need to be treated like any other hibiscus. Hibiscus beetles are a nuisance in the flowers but do not seem to cause any problem with the "fruit" .The flowers only last 4 hours, but can be eaten in salads. This year the flowering stems are way high above the main leaves. Approx double the height. I think the fertiliser is the trick.
