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 roses.
Common Applications-
Shrub or mixed border fronts. Wild, cottage or rose garden. Also effective as a low hedge or edger.
