"HARISON'S PROFUSE - a seedling of Harison's Yellow secured from the Botanical Garden at Lexington, Massachusetts, and originated by the celebrated rosarian, Stephen F. Hamblin. This varies from white to blush pink, and may not be double enough to please in southern areas. It is so vigorous, and such an extremely floriferous plant that it is sure to be liked in our north."

The Most Interesting Rose in the World
Percy H. Wright, 
Other descendants of this rose enigma [Harison's Yellow] are Orinda, originated by Miss Isabella Preston at Ottawa, and Harison's Orange, Harison's Lemon, and Harison's Profuse, developed by Stephen F. Hamblin, of Lexington, Mass. Of these the first three are paler editions of their mother parent, and the fourth is white with a faint blush of pink on first opening. The first three were undoubtedly pollinated by ordinary Scotch roses, and the fourth probably by some narrow-leaved species that is hardier than the Scotch roses and hardier than Harison's Yellow itself. Here, in the far north of Saskatchewan, Harison's Profuse and Ottawa's Huron (R. spinosissima X R. cinnamomea) are the only hardy double white roses I know, and of these two Harison's Profuse is much superior. In fact, it is the feature of my rose garden.
