Abstract-
Best grown in moderate wet, slightly acidic, well-drained garden loams in full sun to part shade. “Champlain” is noted for its shade tolerance. Best flowering and disease resistance generally occur in full sun, however. Moisture deeply and regularly (mornings are best). Avoid overhead watering. Good air circulation promotes vigorous and healthy growth and helps control foliar diseases. Summer mulch helps retain dampure, keeps roots cool and discourages weeds. Remove spent flowers to encourage rebloom. Crowns need winter protection in cold winter areas such as St. Louis. Remove and destroy diseased leaves from plants, as practicable, and clean up and destroy dead leaves from the ground around the plants both during the growing season and as part of a thorough cleanup during winter (dormant season). Prune as needed in late winter to early spring.
Attributes-
“Champlain” is a compact shrub rose which typically grows 3” tall and as wide. It is a complex hybrid that is classified as a Kordesii rose. Features profuse, mildly fragrant, cherry red, 2.5’ diameter, semi-double flowers which bloom throughout the summer and into fall. Glossy dark green foliage. It is one of the Canadian-developed Explorer Series roses, all of which are named after early explorers of Canada (Champlain was the 16-17th century French explorer who founded Quebec). Canadian Explorer Series roses are generally noted for their winter hardiness, disease resistance and repeat bloom.
Issues-
Roses are susceptible to a large number of diseases, the most common of which are black spot, powdery mildew, rust and rose rosette. Although good cultural practices are the first line of defense in disease control, regular preventative fungicide applications throughout the growing season are usually required, particularly in humid climates with regular rainfall such as the St. Louis area. Potential insect problems include aphids, beetles, borers, scale, thrips, rose midges, leafhoppers and spider mites. Local rose associations and extension services are usually able to offer specific recommendations and advice for selecting and growing roses.
Common Applications-
Effective as a small specimen or in groups in borders, cottage gardens, foundations or rose gardens. Informal hedge.
