Chuck Greening, Maryland, has a “current passion for collecting the Cook & Son roses” and requests information about John Cook, a turn-of-the-century Maryland rose hybridizer.   He wants to use the roses in an existing memorial garden in Baltimore, and to give them to cousins on his mother’s side who are related to John Cook and his son, Thomas.    In a succeeding issue of Heritage Roses  we plan to continue following the trail of John Cook and his roses.   ....    He would like sources for the following Cook roses that have disappeared from commerce:
Annie Cook (Tea, 1888)
Souvenir of Wooton (HT, 1888)
Marion Dingee (Tea, 1889)

Editor.  Horticultural Notes.
Deep red colors are rare among roses of the tea scented class, so rare, in fact, that they may scarcely be said to exist, as the two most, strongly marked examples, Marion Dingee and Princesse de Sagan, are almost devoid of the characteristic fragrance, but though probably containing Bengal or China rose blood, are classed as teas, and are otherwise quite typical in habit, growth and constant profusion of bloom. They are well adapted for pot culture and summer bedding, but need housing or thorough protection if left out over winter. Marion Dingee, is deep, rather dark crimson, while Princesse de Sagan has buds and blooms of brilliant velvety crimson, approaching scarlet in its intensity. Blooms are borne in the utmost profusion, singly, and in loose clusters, at all times during growth. The buds are very beautiful, and the open flowers hold their color until the petals fall. This variety has dark, tough foliage, which possesses the merit of being almost mildew proof — a great advantage in humid climates. One of the large growers says he never knew the foliage to be harmed by mildew — the infestation, when present, scarcely spreads from its minute point of origin and dies out without noticeable injury, instead of covering leaf and twig, as in too many other varieties. Marion Dingee is of American origin, and is an excellent variety, but scarcely as pleasing in bloom or as resistant to mildew as the foreign kind.
