Gardeners' Notes:

Positive onagadori On May 7, 2011, onagadori from Lexington, KY wrote:

Mercedes - Gilbert H. Wild - 1980 - 38" tall - 8" flower - Mid-season bloomer - Dormant habit - Diploid - Orange edged yellow gold with raised rose midribs and lemon throat. That is the registration description. To me, it appears almost tan overlaid burnt orange with rose flushing. The overall effect is of sandtone. This cultivar is very hardy, large and floriferous. It is very hardy here in zone 6 and being dormant, is likely hardy further north as well. The Gilbert H Wild plants tend to be very hardy, strong northern performers. This one is no exception. The best part though is that the flowers are large and of a triangular ufo form. The unique colors and subtle coloration makes for a striking plant and the good performance characteristics makes for an easy plant that rewards year after year. Try this cultivar, if you can find it.
