Rosa xanthina, commonly called Yellow Rose or Manchu Rose, is a wild shrub rose that is native to open slopes and scrubby areas in central China. It typically grows on upright, arching canes to 6-9’ tall with a slightly larger spread. Reddish stems armed with reddish-brown thorns are clad with medium green leaves, each leaf having 7-13 small broad-ovate leaflets (to 1” long). Semi-double yellow flowers (to 2” diameter) appear for several weeks from late April into May in a dense bloom. Flowers are followed by attractive spherical to ellipsoid red hips that mature in late summer and persist on the shrub into winter. Best grown in organically rich, medium moisture, well-drained loams in full sun. Tolerates poor soils and some dryness. Also tolerates light shade, but best flowering and disease resistance generally 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, keeps roots cool and discourages weeds. Hardy in zones 5-9.
