Peachblow.—1893. "Seedling rose M-17,806." A hybrid Tea from mixed seed. "The inside of the petals is a pale, silvery, peach-pink like La France; the reverse, dark, bronzy carmine-pink." A Peachblow, a hybrid Tea (Madam Butterfly x Yellow Seedling No. 10), was announded by L. B. Coddington of Murray Hill, New Jersey, forty-four years later; but is evidently something different.
