Ever-blooming Tea Roses.
Madame Martha Du Bourg.
Immensely Free Blooming.
One of the prettiest and best Roses; flowers cup-shaped, with wonderfully pretty crimped petals, giving them a distinct lace-like appearance.  The color is fine creamy pink, with rosy flesh centre; the buds, sometimes the flowers, are beautiful apricot yellow, flushed with orange red.  This lovely variety in open ground is an immense bloomer, producing a prodigious amount of blooms throughout the season; the bush is constantly covered with flowers.  15 cents each; two-year-old plants, 30 cents each.
