General Culture:
Best grown in average, medium moisture, well-drained soil in full sun. Best flowering and disease resistance occur in full sun. Water 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 moisture, 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.
Noteworthy Characteristics:
This upright, bushy, shrub rose is a David Austin English rose which typically grows 5-8' tall and 5-8' wide. Size depends in large part on climate and environment (e.g., generally taller in hotter climates). Features large, intensely fragrant, bright yellow, double blooms (3.5" across) which occur in clusters on arching canes. Blooms well from spring to fall. Leathery, dark green foliage. Large yellow hips in fall. Named for English rosarian Graham Stuart Thomas.
Problems:
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.
Uses:
Shrub or mixed border. Wild, cottage or rose garden. Excellent specimen. Also effective as a hedge.
