Hibiscus rosa-sinensis 'Adrenalin'
This is an outstanding Australian Hibiscus which was bred and released by Phil and Mavis Barry in 2003. The flower is so large and heavy it often points downwards so I had to pick this one to get a good picture and thus appreciate its form in close up. The colour is a vibrant hot orange with golden yellow reverse and pale pink centre. The central staminal column is fused with fluted, twisted and quilled petaloids which give it a marvellous sculptural quality. Almost hidden amongst these central petaloids is a hot pink 'raspberry' of fused stigma pads attended by a small group of tufted gold anthers. 'Adrenalin' was bred from a pollen parent of 'Jol Wright' and a pod parent of 'Harvest Moon' which are both prolific varieties. 'Jol Wright' was once described as 'without a doubt the best Australian bred hibiscus', though as it requires grafting onto a more hardy variety for successful growth it is perhaps less well known than it should be.
