"ROSS RAMBLER - a rose found growing in a plantation of evergreen trees at the Dominion Forestry Nursery, Indian Head, Sask., where it attained a height of 25 feet. Apparently it is not nearly so tall elsewhere. Rather similar to R. Beggeriana in description, and it also produces fall bloom, though it never blooms abundantly at any one time."

In "Progress in Breeding Hardy Roses," Isabella Preston says,

A number of seedlings were grown from a plant raised by cross pollinating the Ross rose with pollen from a variety of rugosa X Eglanteria parentage. These varied greatly as one would expect from such mixed parentage but none showed any sign of the climbing habit. Several are being kept but so far only one has been named. It makes a large bush seven feet tall and is well clothed with leaves which have a faint sweetbrier fragrance. The single flowers are white and there are a dozen or more in a cluster but the special interest of this plant is the continuous blooming habit. In 1945 the first blooms opened on June 11 and all summer long the bush was never without a flower and even on October 18, there were buds ready to open as well as bright red hips. It has been named Nascapee.

In "Central Canadian Rose-Breeding" Isabella Preston says,

R. rubrifolia X Ross Rose was made successfully, and the seedlings have reddish foliage similar to the female parent. The flowers have a few extra petals, but the plants are not attractive, and are mentioned only for the purpose of recording the cross.

In "The Arcticness of Various Roses" by Percy H. Wright,
"...-30℉ ...hardiness is not adequate for a large region in prairie Canada and parts of the adjacent northwestern states. With us, winter temperatures reach -45℉ every season and often descend considerably lower. In 1936 we experienced -59℉., and 57 consecutive days passed when the thermometer never once lifted above -29℉., either night or day...the Ross Rambler, of which an account was given on page 115 of the 1935 Annual, seems hardy through the prairie area, and, in addition, possesses the everblooming quality in greater abundance than does R. rugosa.

The Ross Rambler and Other Hardy Roses

By THE EDITOR

The story of the discovery of the very hardy climbing rose known as the Ross Rambler is related in the following quotation from a letter to the Editor written by Norman M. Ross, Chief of Tree Planting of the Department of Agriculture at Indian Head, Saskatchewan:

"Just as a matter of identification, this rose has been called the Ross Rambler by some of those who have been interested in it. I have no idea where this plant originated, but we found it growing in our shrub borders. It is a rose of true rambling type, and absolutely hardy up to the tips. It must have been growing for many years before it was discovered. The original plant is in a rather thick growth of dwarf pine and lilacs, not at all an ideal condition for rapid growth. It spreads very freely from underground suckers and many of the shoots among the shrubs are now eighteen to twenty feet long with no sign of winter-killing. When transplanted, it grows very rapidly and will reach a height of ten to twelve feet in two seasons' growth. The flower is not at all conspicuous. It is single, about an inch and a half in diameter, and pure white. It may prove valuable for hybridizing with other varieties in order to produce a rambling rose suitable for prairie conditions for which, so far, no rambling rose has proved hardy."
