K. P. Jones, Barrington, Rhode Island. Wichuraiana Hybrids.
The Brownells have also created very hardy and disease-resistant hybrid teas, practically every one of which has the blood of one or more of the three Van Fleet Wichuraiana hybrids mentioned before. [‘Dr. Van Fleet’, ‘Glenn Dale, or ‘Mary Wallace’]  If  these roses are properly cared for and allowed to grow, with only such pruning as is necessary to hold them to a pleasing shape and to clear out dead wood, then most of these Brownell "sub-zero" hybrid teas will grow to amazing size. ‘Lily Pons’ has been grown to five feet in diameter and seven feet in height and M. B. to nearly the same size… M. B. is a vigorous grower and makes a handsome compact bush. In my garden this rose bloomed every month from June to November.

Proof of the Pudding.
'M. B.' HT. Bic. (Brownell '42) ARA '43. the only report is from Wilcox, Minn. (8 pl., 2 yr.) who tells of wonderful flowers in June with deep green, holly-like foliage. There are not so many flowers during summer, when form is poor; one of those roses which are good in spring and fall, but plants will black-spot unless well protected.

R. Marion Hatton.  The World's New Roses. 
The Brownells have a progeny of Van Fleet and Druschki, which they call M.B. I did not see it, but description says 4 to 5 inch blooms of orange-pink, overlaid salmon and yellow, fragrant, twenty-five petals. The ancestry promises an unwieldy plant.
