Peter Henderson also introduced a number of roses, mostly sports of those growing in his nursery. Of at least seven roses, four are still in commerce today. ‘American Banner’ and ‘Snowball’, both sports, have disappeared, as has his hybridized rose ‘Dinsmore’, 1888.

Dinsmore
One is first impressed with the extremely sweet fragrance of the Dinsmore. Then the dark scarlet color is noted, and the general contour of the double flower is taken into consideration, and it becomes a favorite. The blooming is constant and profuse. The plant is vigorous, with long shoots, and is exceptionally free from disease and insects. All of its virtues considered, the Dinsmore is a Rose that should find a place in every garden- especially where there is a pretense of variety.

Some two or three years ago it was intimated that the Dinsmore and Mme. Chas. Wood were probably identical, and in a late catalogue they are noted as such. As some time has elapsed since this was first spoken of, cannot someone now throw some light on the subject?
[Mr. J. N. May, page 244, says that Dinsmore is a seedling of Mme. Chas. Wood, and in Ellwanger's book on The Rose they are classed as distinct. ED.]
