[From "Danish Heritage Roses", by Jens Otto Pedersen, pp. 21-23]
Valdemar Petersen in 1966 introduced the spinosissima hybrid ʻAïcha’ (Souvenir de Jacques Verschuren × Guldtop). This bush rose is in many ways similar and equal to the Kordes’ Frühling-roses. An early bloomer its yellow flowers almost covering the bush is a potent announcer of summer. ʻAïcha’ is named after the maybe most beloved of Muhammed’s wives

[From "Hardy Roses in Iceland", by Vilhjálmur Lúðvíksson, pp. 37-41]
Another good and more unexpected performer was the Danish born 'Aicha' from the fingers of the legendary breeder Valdemar Petersen. A few days of sunshine in late July produced a rich flush of golden flowers on 'Aicha' that kept long into the cloudy period that followed

‘Aïcha’ = Ancien – Pimprenelle – jaune intense. L’atout des rosiers pimprenelles est leur rusticité, et bien des hybrideurs ont fait appel à eux pour produire des rosiers résistants au froid, tel Kordes en Allemagne… Il existe deux sortes de rosiers pimprenelles: le type européen, plutôt bas, et le type asiatique, plus élevé… Petersen, Danemark, 1966. ‘Souvenir de Jacques Verschuren’ x ‘Guldtop’.

"Twenty of the Best Hardy Roses for Nurserymen Selling Roses in New Hampshire" by Mike Lowe
The following are ten of the best repeat-flowering roses. Keep in mind that most miniature and Rugosa roses are very hardy.
Aicha. 1966. Three-inch flowers—deep ocher-yellow fading to lighter tones, ten petals, semi-double. Buds long and pointed. This is a fairly new Spinosissima hybrid from Peterson in Denmark; it has a very strange reflowering habit in that it blooms in mid-June on old wood and then immediately reblooms on new wood, extending the spring flowering season from four weeks to six; then it doesn't bloom again until September. Its growth habit is also a bit unusual here in Nashua—budded on Canina laxa, the bush is ten feet high and six feet wide after three years. On its own roots, it's only four feet by three. And on Multiflora, it is six feet by four. All have survived with little or no dieback. (Note: bud unions are buried two inches below the ground.)

Parentage unknown, Rosa spinosissima hybrid. Description... Each flower's immense outer petals cradle five inner petals, which in turn encircle the largest grouping of stamens [Osborne has] seen in a rose... sunshine-yellow color... vigorous and thorny stems, which can be trained to form a spectacular climber, one that is perfectly happy to spend the winter in the chill wind... healthy deep green foliage.
