  • circleLife cycle

    Rosa 'Helen Knight', commonly known as the Yellow Ecae Rose, begins its life cycle as a seed or more commonly through vegetative propagation techniques such as cuttings or grafting. Once established, the plant enters a vigorous growth phase, developing a strong root system and foliage in its first year. The following spring, it enters a vegetative stage with the emergence of pinnate leaves and thorny stems. Flower buds develop and bloom into its characteristic bright yellow flowers, which are typically hermaphroditic and can self-pollinate or be pollinated by insects, leading to the production of fruit, or hips, containing seeds. After the flowering period, which can last throughout the growing season with proper pruning and care, the plant goes into a dormancy phase during colder months, conserving energy for the next cycle. Over the years, the Yellow Ecae Rose can become a hardy perennial fixture in a garden, with a life span that can extend numerous years with proper maintenance.

      Early Spring

    • The Rosa 'Helen Knight', commonly known as a rose, is typically propagated through softwood cuttings. This method is popular because it often yields successful results and replicates the parent plant's characteristics. During the late spring to early summer when the rose's new growth is still tender and green, you cut a stem of about 6-8 inches (15-20 cm) just below a leaf node. The lower leaves are removed, and the cut end is dipped in rooting hormone to encourage root development. This cutting is then planted in a well-draining soil mix, with the remaining leaves kept above the soil surface. To maintain humidity, a clear plastic cover can be placed over the cutting. The cutting should be kept in a warm location with indirect light and the soil should be kept moist until roots have established, which typically takes 4-8 weeks.
