Sea Shell (Sass)...$1.00
The blooms of this newest Sass seedling are immense in size. The petals are an iridescent shell-pink with a rich satiny texture and the centers of the flowers are full of shining golden-yellow stamens. We believe this is the first time that this variety has appeared in an Eastern grower's catalogue. (Introducer's description.)
