Chickasaw X Golden Comet

Here are Bruce Clyburn's seedlings of 'Chickasaw' X luteum 'Golden Comet' a cross by Sally and John Perkins.

'Chickasaw' is a "pollen sterile" tetraploid found by Clarence Towe in the wild and R. luteum 'Golden Comet' is a tetraploid selected by the Rhododendron Species Foundation.

'Chickasaw' was suspected of being a triploid but flow cytometry indicates 'Chickasaw' is a tetraploid.
