 Charles H. Rigg.  Exhibiting Roses of Quality.
In this category we have a new rose called Margarete Gnau, a Hybrid Tea introduced by Herr Krause in 1931.  The flowers are large and full, with a splendid point, and carry forty to forty-five petals.  Color is flesh-white on a yellow ground.  Mr. Walter Easlea, a good judge, writing about this rose in Gardening Illustrated, says “Margaret Gnau is a variety every exhibitor will want.  One would expect a rose of its quality from ‘Mrs. Charles Lamplough’ x ‘Souv. de H. A. Verschuren’, and I can recommend it to all exhibitors.

Margarete Gnau  A really high-quality bloom in every respect.  The colour, however, is neither white nor yellow, which somewhat detracts from its otherwise good quality.
