  • circleLife cycle

    Genista tinctoria 'Royal Gold', commonly known as 'Royal Gold' broom, begins its life as a seed, which upon germination, develops a root system and shoots that emerge from the soil. The plant then enters a vegetative stage, growing leaves and stems, and once mature enough it will produce its distinctive yellow pea-like flowers in late spring to early summer. After pollination, typically by insects, the flowers produce small pods that contain seeds. These seeds are eventually dispersed, possibly by wind or animals, to begin a new generation. In the fall, the plant prepares for dormancy by shedding its leaves and entering a rest period through winter months. With the return of favorable conditions in spring, 'Royal Gold' resumes growth, completing its annual cycle.

  • sproutPropogation

    • Propogation time

      Early Spring

    • Propogation: The most popular method of propagating the Dyer's Greenweed is through semi-hardwood cuttings. This is typically done in late summer after the shrub has flowered. Cuttings should be around 4 to 6 inches (10 to 15 centimeters) long and have several nodes. The lower leaves are stripped off and the cut end is dipped in rooting hormone to facilitate root development. These prepared cuttings are then placed in a well-draining soil mix, ensuring at least one node is buried beneath the soil surface. The soil should be kept consistently moist, but not waterlogged, and the cuttings should be placed in indirect light until roots have developed, after which they can be transplanted.
