  • water dropWater

    The Moss Rose requires consistent moisture, so gardeners should water when the top inch of soil feels dry. This usually translates to about 1 to 1.5 gallons of water per week, depending on climate conditions. Deep, infrequent watering is preferred to encourage deep root growth. During hot, dry spells, watering frequency should be increased, whereas cooler, rainy periods may require less. Always avoid overhead watering to minimize the risk of leaf diseases.

  • sunLight

    The Moss Rose thrives in full sun, needing at least 6 hours of direct sunlight daily for optimal growth and flower production. The ideal spot is an open area without shade from trees or buildings, ensuring the plant gets plenty of light throughout the day.

  • circleLife cycle

    The life cycle of Rosa 'William Lobb', commonly known as Moss Rose, begins with seed germination when soil temperature and moisture levels are suitable. Seedlings emerge and develop into young plants, establishing a root system and foliage through vegetative growth. As the plant matures, it enters the flowering phase typically in late spring or early summer, producing fragrant, purple-pink flowers that attract pollinators. After pollination, flowers develop into fruit known as hips, which contain seeds for the next generation. During the fall, the plant prepares for dormancy by slowing down growth and transferring energy to the roots; in winter, the plant lies dormant, conserving energy until the return of favorable growing conditions in spring. Each year, the perennial Moss Rose can go through a similar cycle of growth, blooming, and dormancy, gradually becoming larger and more robust with each season.

      Spring-Early Summer

    • Rosa 'William Lobb', also known as the Moss Rose, is commonly propagated through softwood cuttings. This method is the most popular because it is straightforward and tends to have a high success rate. The best time to take softwood cuttings is in late spring to early summer when new shoots are growing but not yet mature. Cuttings should be about 6 to 8 inches (15 to 20 centimeters) long and should include at least three sets of leaves. Remove the leaves from the lower half of the cutting to expose the nodes, as this is where the roots will develop. It is advantageous to dip the cut end in rooting hormone powder before planting it in a well-draining growing medium. The cutting should be kept moist and in a warm, shaded environment until roots have established, which typically takes several weeks.
