From The Graham Stuart Thomas Rose Book,
p. 225: These "Ayrshires,"
[such as Bennett's Seedling, Dundee Rambler, Venusta Pendula, Splendens]...apart from their hardiness, have perhaps two attributes which might still recommend them for use today. One is that they are prostrate unless given support, and would presumably make a good weed-proof ground cover; the other is their value for climbing into trees.
From Visions of Roses
, by Peter Beales, p. 62: Ayrshires
are hybrids of Rosa arvensis
; they generally make ideal ground coverers and are also good for growing up into the branches of trees. [See 'Splendens'
From Roses: An Illustrated Encyclopaedia and Grower's Handbook, by Peter Beales, p. 3: R. arvensis was responsible for starting off those interesting ramblers, the Ayrshires.
From The Book of the Rose, 2d ed., by Andrew Foster-Melliar, p. 20: The Ayrshire Rose R. arvensis - This too, as its name implies, is a native species, found also throughout Europe. They have been well called running Roses, for the growth is extremely long, rapid, and slender. Being very hardy and ready to grow anywhere, they are better adapted for trailing...Several of the Ayrshires have probably been slightly hybridised, a mark of the true sorts being that the flowers are not borne in clusters.
