"Bad Roses." by W, D. Prior
[Geant des Batailles] is a bad rose, and the parent of numerous seedlings among which I do not know a superior variety. [...] Eugene Appert, the best of its descendants, has but the one point- coulour- in its favour, and will, I suspect, be relegated at an early date from the "stand" to odd corners in the border.
