Best grown in average, moderate wet, well-drained soil in full sun to
part shade. 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,
keep roots cool and discourage 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 clean-up during
winter (dormant season). Prune as needed in late winter to early spring.
This floribunda rose is a vigorous, compact, bushy, rounded shrub which
typically grows 2” tall with a slightly larger spread. Features
clusters of fragrant, double flowers (to 3’ across) which open salmon-pink
and mature to creamy white. Blooms in May with good repeat bloom throughout
the summer. Small, dark green foliage. Few thorns.
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 summer
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
Shrub or mixed border fronts. Wild, cottage or rose garden. Also effective
as a low hedge or edger.
