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.
“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.
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.
Effective as a small specimen or in groups in borders, cottage gardens,
foundations or rose gardens. Informal hedge.
