    Sweet William, known scientifically as Dianthus 'Wp04 Xanthe', requires moderate watering. It should be given enough water to keep the soil moist but not soggy. Allow the top inch of soil to dry out before watering again. Typically, this equates to watering once a week, but this can vary depending on climate and weather conditions. For an average-sized plant, using approximately one gallon of water every week during the active growing season should suffice. Adjustments should be made during the dormant season or periods of rainfall to prevent overwatering.

  • sunLight

    Sweet William thrives best in full sunlight to partial shade. Ideally, it should receive at least six hours of direct sunlight daily. A spot that provides morning sunlight and afternoon shade would be ideal, as the intense heat of the afternoon sun could be too stressful for the plant.

  • thermometerTemperature

    Sweet William is comfortable in a wide range of temperatures but performs best when daytime temperatures hover around 60-70 degrees Fahrenheit. While it can withstand light frosts, it should be protected or brought indoors if temperatures are expected to dip below 40 degrees Fahrenheit. At the other end of the spectrum, the plant may struggle if exposed to temperatures consistently above 85 degrees Fahrenheit.

  • scissorsPruning

    Pruning Sweet William is important to promote vigorous growth and to maintain a tidy appearance. Deadhead faded flowers regularly to encourage more blooms. After the main blooming period, cut back the stems to about half their height to potentially stimulate a second bloom. The best time to do a major pruning is immediately after the plant finishes its main flowering cycle.

  • circleLife cycle

    Dianthus 'Lady in Red', also commonly known as Sweet William, begins its life cycle as a seed which, when sown and given appropriate conditions, will germinate and sprout. The seedling stage is characterized by the emergence of a pair of true leaves, which will further develop into a rosette form as the plant enters the vegetative stage. Here, the plant focuses its energy on leaf and stem growth, establishing a strong root system. Subsequently, the reproductive stage is marked by the development of flower stems and the blooming of vibrant red flowers, often in late spring to early summer. After pollination, the flowers produce seeds, completing the reproductive cycle. Finally, depending upon the climate, Dianthus 'Lady in Red' can act as an annual, biennial, or short-lived perennial, with the plant eventually senescing and dying, leaving seeds to begin the next generation.

      Spring to Summer

    • Propogation: The Sweet William, known botanically as Dianthus 'Lady in Red' = 'Wp04 Xanthe' (PBR) (p), is commonly propagated through stem cuttings, a method that offers a reliable means of maintaining the parent plant's characteristics. The optimal time for taking stem cuttings is late spring to early summer when the plant's growth is most vigorous. To propagate Sweet William by stem cuttings, one should select a healthy, non-flowering stem and make a cut to obtain a segment about 3 to 5 inches long (approximately 7.5 to 12.5 centimeters). Remove the lower leaves and dip the cut end in rooting hormone powder to enhance the chances of success. The cutting should then be planted in a mix of peat and perlite and kept under conditions of high humidity, at a temperature of about 70 degrees Fahrenheit (21 degrees Celsius), till it has rooted, typically in a few weeks. Once established, the young plants can be transplanted to their final location in the garden.
