Walter Schowalter notes:
Albertan - apparently R. woodsii, op sdg of Athabasca raised by Robt. Erskine, Rocky Mt. Hse. Height unknown, probably 1.2m. Prickles on primary wood numerous, on secondary wood small and scattered, prominent each side of stipules. Leaflets 7 - 9, flat on established portions, troughed on new growth. Leaves 9.9 cm long on old wood to 14.0 on new; leaflets 4.5 cm x 2.5 cm on new wood and 3.5 x 2.0 cm on old, ellipse shaped. Fruit on upright pedicels, scarlet, ovate-conic. Calyx partly open. Fruit 1.5 long x 1.3 w. Blossoms medium size (none available for measurement) petals 15, bright rose pink, freely produced. A bright and cheerul ornamental, superior to its parent Athabasca.

Walter Schowalter notes:
Alison - Hybrid rugosa. Lower growing than Will Alderman, and less subject to chlorosis. Neater leaves and flowers than Will alderman, about the same color, but less floriferous. A good rose.

Walter Schowalter notes.

Amelie Gravereaux - Hybrid Rugosa. Height 4 - 5 feet, not completely hardy [in Zone 3]. Flowers large, bright red, double, not as freely produced as Hansa, nor over as long a season.

(1985)  
 
Walter Schowalter notes 1985:
Ames 6 - Multiflora and Blanda hybrid. Rather sprawling plant, thornless red canes, reasonably hardy [zone 3] kills a little some winters. Reaches 7 feet. Masses of clustered, single, fringed, small pale pink blossoms in spring, followed by red hips. Blooms once. No rust so far.

[this may be the same plant as Ames 5 - Margit Schowalter]

Walter Schowalter notes :
Assiniboine - hybrid arkansana. Grows 3-4 feet tall. Showy, semi-double bright red roses produced in mid-season. A mass of color. Reasonably hardy [zone 3] sets seed. Makes suckers, and is subject to rust, but anyone with space available should grow it.

Personal correspondence Robert Erskine to Walter Schowalter :
I have found some interesting plants of R. acicularis. The one I named Aurora" has red flowers with thick wide petals (5) and good foliage that colors well in the fall. It is the only non-suckering wild rose that I have ever observed, so is slow propagating.

(1985)  
 
Walter Schowalter notes :
Aurora - R. acicularis selected from the wild by Robert Erskine. An excellent shrub for a wildling, 5-6 feet tall. Large, attractive deep colored foliage, and large, single, bright deep rose to red flowers, followed by typical acicularis fruit. No rust so far. A choice wild rose.

(1973)  
 
Walter Schowalter notes:
Aurora - R. acicularis, found by Robt Erskine north of Leslieville. Notable in two respects: 1. Blossoms are large, and bright red. 2. Plants send out suckers very rarely. Leaflets 9, elliptic, midrib curved, slightly troughed. Leaf 11 cm. Leaflets 4.0 x 2.3 to 2.7 x 1.5. slightly rugose.

Walter Schowalter - Alberta, Canada notes:
Austrian Copper - R. foetida bicolor - Grows to 7 feet, reasonably hardy. Single bright orange, very startling. Most people love it, but I think it swears at everything else, and should be planted by itself. Blooms once, sets seed. I have seen no black spot.
