cranesbill [Rothbury Gem]


Geranium 'Rothbury Gem', commonly known as cranesbill, is a delicate and charming perennial that boasts a low-growing, clump-forming habit. This plant is appreciated for its ornamental qualities, particularly its lovely foliage and attractive flowers. The leaves of the cranesbill are subtly lobed, with a soft green color that provides a lush backdrop to its blooms. These leaves may take on varied tones throughout the seasons, contributing to the plant's visual interest throughout its growth period. The flowers of the 'Rothbury Gem' are truly the stars of the show. They emerge in a striking shade of pale pink, with each bloom featuring five rounded petals that create a classic, simple flower shape. At the center, contrasting veins in a deeper pink hue draw the eye and add depth to the blossom's appearance. The stamens are prominently displayed, with tiny anthers that may be seen upon close observation, adding to the delicate charm of the flowers. Furthermore, the blooms are held aloft on slender stems which rise just above the foliage, creating a floating effect that is visually appealing in garden settings. Without focusing on the size, it is clear that this cranesbill variety presents a lovely and graceful presence that can soften the edges of borders, rock gardens, or serve as an underplanting for taller plants. Its endearing appearance makes it a favorite among gardeners who appreciate subtle beauty and the romantic ambiance these cranesbill flowers can impart to a garden landscape.

  • circleLife cycle

    The life cycle of the Geranium (Cinereum Group) 'Rothbury Gem' begins with seed germination, taking place in warm, well-drained soil during spring. Seedlings emerge and grow into young plants, developing a rosette of deeply lobed leaves. As the plant matures, it produces long, slender stems and clusters of delicate, pastel-colored flowers that bloom from late spring to summer. After flowering, the plant sets seed, which can be collected for propagation or allowed to self-seed in the garden. In the fall, the geranium may die back somewhat, but as a perennial, it will regrow from its rootstock the following spring. Throughout its life, 'Rothbury Gem' will periodically require division every few years to maintain vigor and prevent overcrowding.

      Spring to Summer

    • The Geranium (Cinereum Group) 'Rothbury Gem', commonly known as cranesbill, is most effectively propagated through cuttings. This popular method involves taking a 3-4 inch (approximately 7.5-10 centimeters) stem cutting from a healthy parent plant during the active growing season, typically in late spring or early summer. The cutting should have a few leaves and be snipped just below a leaf node, where the concentration of growth hormones is high. To encourage root growth, the base of the cutting can be dipped in rooting hormone powder before being placed in a pot filled with a well-draining soil mix. The soil should be kept consistently moist but not soggy, and the cutting should be placed in a warm area with filtered sunlight. Roots typically develop within a few weeks, at which point the new cranesbill plant can gradually acclimate to outdoor conditions before being transplanted to its final location in the garden.
