Another new variety, after the style of the Poulsen Rose, is Ellen Willmott. It is one of the most beautiful single Roses I have seen, the colour of the blooms reminding me of ripe peaches. I know there are some who can see no beauty in a single Rose, but I feel sure that if they could but see a bowl of these lovely flowers they would find it exceedingly hard to resist their charms.
