Jennifer Howard. Save Our Tea Roses. Many of you will know the pale pink cupped Tea Rose with a "gutsy" constitution, found growing throughout New Zealand. "Teddy" Roosevelt wore a flower of it in his buttonhole. America and the rest of the world seemingly know it as Duchesse de Brabant. In New Zealand we love it and grow it as 'Irene Watts'.

p80. Picture. Irene Watts. [note - this picture is in the Helpmefind Photos]

p72 ....and Irène Watts, all China Roses, were listed here in early catalogues, ... but the last named, a beauty flushed with pink and salmon, adorns our trough garden. Rival de Paestum was one of the parents of another rose we grow nearby. This is Madame Laurette Messimy with loosely semi-double blooms of rose and salmon flushed with yellow – a rose from which Irène Watts was bred.
