'Trier'. Lambert, 1904 Seedling of 'Aglaia'. The multiflora rambler 'Trier' was one of the first truly hardy, perpetually blooming rambling roses. It was introduced by Peter Lambert, who named it after his native City, Trier, Germany. Lambert said that 'Trier' was a cross between 'Aglaia' and a rosy pink hybrid perpetual, 'Mrs. R. G. Sharman-Crawford'. A chromosome count has revealed, however, that this is not possible, and it is now generally agreed that 'Trier' is simply a seedling of 'Aglaia'. Its heritage can be traced back through 'Aglaia' to the Noisettes and the musk rose. Of the many important roses that Lambert created, 'Trier' was perhaps the most significant, for at the time of its introduction it was the only hardy, ever blooming climber. It became popular as a rose that would cover a pillar or a wall with white blossoms all summer.....
'Trier' has pink buds that open quickly to small, cup-shaped flowers with twelve to fifteen creamy white petals that retain only a trace of pink. There is a hint of yellow at the base of each petal, and this, together with the bright yellow anthers, gives the flowers a distinctly golden-centered look. These one-inch, semi-double blooms are arranged in clusters of five or more on a lateral, but the clusters do not have the pyramidal form that one would expect from a descendant of R. multifiora. They do, however, have the characteristically sweet multiflora fragrance. 'Trier' starts blooming in late May, continues its lavish display through June, flowers sporadically during the summer, and then puts on another generous flush that lasts from October until the first frost. After the flowers are gone there are many hard, round hips. Given its heritage, it is no surprise that 'Trier' is a vigorous climber. In two years it can grow ten feet high and twelve feet wide. It has a twiggy growth habit, very much like that of a Noisette, or at least a rose with China influence. It also has the multiflora trait of sending out many long, continuing laterals and a few basal canes. The young canes are smooth and plum-colored, like those of the variety of multiflora that has no prickles. This coloring makes them attractive in the winter garden. 'Trier' is vigorous "enough to surmount a seven-foot lattice. When it reaches the top, the canes continue to grow and they arch over, sending down a cascade of fragrant blooms. Other arching canes develop all over the plant, especially in the middle section. The bush becomes very wide and spreading, so in spite of the fact that it was originally considered a pillar rose, that is not really the best way to grow it, because you will have to cut away many of the beautiful canes and much of the flowering wood to keep the plant under control. 'Trier' is more suitable for a lattice or other wide support, which it will cover with dense foliage. As the plant grows, it becomes rather rigid and stiff, so it is important to tie the new canes securely to a support as soon as they are long enough. Once the bush is established, the center becomes dense with old dead wood and must be thinned annually. The light green leaves resemble those of the wild R. multiflora in their large size and their elongated, pointed shape, but they are more attractive because they are smoother, like those of the Noisettes. The foliage has above-average disease resistance and is long lasting, holding onto the bush well into the cold of the winter....

....Pemberton used a bushy, long-stemmed cluster rose called 'Trier', bred and introduced by Lambert of Germany in 1904. He could see at a glance that the habits of this variety were not too far removed from the Polyanthas, although much taller. He probably knew that 'Trier' was a seedling from a french rose called 'Aglaia', a climbing Polyantha of 1896, the parents of which were Rosa multiflora and 'Reve d'Or', a Noisette from as far back as 1869. There is no reason to doubt this pedigree, for at certain times of the year considerable family resemblances, especially in foliage, can be seen between great-grandparent 'Reve d'Or' and some of Pemberton's Musks. Obviously , too, it was from this lineage that his roses inherited their musk-like scent.

p81. 'Trier' was raised in 1908 by Peter Lambert, and was possibly a seedling of a yellow Rambler called 'Aglaia', which Lambert had introduced in 1896. It was a strong, 2 - 2.5m (6-8 ft) shrub with semi-double scented blush-pink flowers which shaded to yellow at the petal bases, and was one of a small group known as the Lambertianas, which never achieved much popularity outside Germany.

p140. 'Trier' 1904. An 'Aglaia' seedling. Included mainly for historical interest, as the ancestor of all Hybrid Musks. Semi-double fragrant blush-white flowers, merging to yellow at the base. Lax. 2 x 1.8m (7 x 6 ft).

In 1896 when ramblers were fashionable, Schmitt of Lyons raised one by crossing R. multiflora with the Noisette 'Reve d'Or', and called it 'Aglaia'. A few years later Lambert of Trier crossed this rose with the Hybrid Perpetual 'Mrs. Sharman Crawford' - but the evidence of the chromosomes shows that the cross did not "take", and the resulting seedling, 'Trier' was evidently a self-seedling from 'Aglaia'. Just as the once-flowering rambler 'Champney's Pink Cluster' when selfed produced the perpetual semi-climbing Noisette Rose, so 'Aglaia' yielded a perpetual semi-climber. 'Trier' was semi-double, with pale yellow flowers flushed with pink, and grew to a maximum height of about six feet.
