More information
American Pillar has been widely grown since its introduction. It flowers very abundantly, but relatively late, when many other roses have passed peak bloom. It propagates readily by cuttings, is straightforward to grow, and is the hardiest of the Van Fleet roses. The flowers are bright crimson with a distinct white center and a large cluster of golden stamens; in hot weather and strong sun the color becomes paler. It grows and blooms across climates ranging from very hot to very cold. Flowers appear in large clusters and are followed by scarlet spikes. The shrub is very vigorous, producing many thin shoots covered with large thorns. The foliage turns slightly bronze in early autumn and remains on the plant for a long period.
Flowers are borne in trusses of 5–20 in very large numbers. They are bright crimson with a white center and bright golden stamens; in heat the color is paler. The foliage is large, glossy, and disease-resistant. Shoots are fairly stiff, upright, bare at the base, and are best trained horizontally. They reach 3–4 m; after 3–4 years the older shoots begin to die back. Very easy to root from cuttings.
Buds are globular. Flowers are carmine-pink with a white eye, saucer-shaped, open, large (4–5 cm), single, in large inflorescences of up to 20, on long, slender pedicels. Leaves are leathery, shiny, rounded. Spines are large, hook-shaped, with a broad base. Shrubs are very strong (up to 5 m). Flowering is abundant, lasting 35–40 days. Winter-hardy. Sensitive to powdery mildew.
Shade-tolerant variety.
