Alyogyne huegelii ‘Swan River’ BLUE HIBISCUS Medium purple blue, darker than the "regular old trade form," which is actually the variety ‘Santa Cruz,’ but not as dark as ‘Monterey Bay.’ Has better form than either, more compact and denser foliaged, and the flowers are thicker textured, somewhat fuller, and with a conspicuous overlapping “propeller” form. This variety is close to the form found in nature (or rather, formerly found in nature) near Moora, Western Australia. In fact, this form is probably the result of that Moora form crossed with ‘Santa Cruz,’ as is ‘Monterey Bay.’ During the deep drought of 1977-78, the Arboretum at UC Santa Cruz had a severe deer problem, resulting in the continual browsing of the young growth of the Alyogynes growing there. The plants developed into beau... read more

I am trying to grow this plant in Naples, Florida. Given our prolonged drought, I thought that I might have a chance.

This cultivar can get very leggy unless frequently pruned to get to put out more shoots from base to form a denser bush. Do not allow to sit in water, place in well drained area. This one cultivar has dark purple flowers that are are about 4 inches wide. In my zone 9, it will bloom all winter if mild. It also will survive limited frosts.
