I found this interesting description for Helen Good online in a 1917 American florists' catalogue.
"HELEN GOOD (The Beauty Cochet) — What the
introducers say: "This is a true Cochet Rose,
and after two years' trial in the garden we
pronounce it as good if not better than any
Rose for the garden ever sent out. We bought
the entire stock of this Rose, paying $1,000 for
two plants, this being by far the highest re-
corded price ever paid for any Rose. The color
is a delicate yellow, suffused with pink, each
petal edged deeper, very chaste and beautiful.
The color, with its immense size and exquisite
form, makes it without question the greatest
Tea Rose ever introduced, and we are proud to
have brought it out."
