Definition on a Corona:  A crown-shaped, funnel-shaped, or trumpet-shaped outgrowth or appendage of the perianth of certain flowers, such as the daffodil, Hoya, or the spider lily. Also called crown. Here is where you will find photographs of dried coronas of many of the Hoyas I have grown.  Each dried corona is almost a work of art in itself.  All photos were taken with the Canon EOS 60D combined with the Canon MP-E 65mm Macro Lens.  Photos will be found as subpages of the Corona Page.
