Culture
Best grown in medium moisture, slightly acidic, well-drained garden loams in full sun to part shade. Best flowering and disease resistance generally occur in full sun, however. 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, 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.
Noteworthy Characteristics
Rosa is a genus of about 150 species of deciduous (occasionally evergreen) shrubs and climbers noted for their beautiful, often fragrant, single, semidouble or double flowers which are borne singly or in clusters on often prickly stems clad with 5-9 leaflets often having toothed margins.
Shrub roses are usually large-growing bushes between 4-10 feet tall and as wide. They are a very diverse group of hybrids and usually produce clusters of flowers several times a year but some may bloom just once in spring. They do not require the heavy pruning required of hybrid tea, floribunda and grandiflora roses unless being pruned to control size. Plants can be allowed to grow large with minimal pruning.
Genus name comes from the Latin name for rose.
‘Scrivjean’ is a low-mounded shrub rose that typically grows to only 1-2’ tall and slightly wider. It is marketed as part of the OSO EASY rose series under the trade name of HONEY BUN. It is noted for its low-mounding plant habit, fragrant semi-double flowers in pastel shades, glossy dark green leaves, vigorous growth habit and good disease resistance. Flowers (each to 2” diameter) bloom in terminal clusters (3-5 flowers per cluster) over a long late May to frost bloom period. Flowers typically vary in color from blush-pink to butter yellow to creamy white. Flowers are slightly fragrant. Compound glossy green leaves (to 3" long) have ovate leaflets (to 1" long) with serrulate margins. Parents of this rose are Rosa 'Flower Carpet' (female) and Rosa 'Shine On' (male). U.S. Plant Patent PP21,611 was issued on January 11, 2011.
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 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.
OSO EASY roses have good disease resistance, particularly to black spot and powdery mildew.
Uses
This low-mounding rose is appropriate for border fronts, cottage gardens, foundations, rose gardens or other small sunny areas of the landscape.
