  • water dropWater

    The Butterfly Bush should be watered deeply, allowing the soil to become slightly dry between waterings. During the first growing season, establish a deep and extensive root system with regular watering, providing the equivalent of about 1 inch of rainfall per week. As a guide, this is roughly 0.6 gallons per square yard of soil per week. Once established, Butterfly Bushes are quite drought tolerant and will require less frequent watering, possibly once every two weeks unless there are conditions of extreme heat or drought. It's important not to overwater, as this can lead to root rot.

  • sunLight

    Butterfly Bush thrives in full sun but can tolerate partial shade. It performs best with at least 6 hours of direct sunlight each day. Plant it in a location where it will receive ample sunlight during the morning and afternoon to encourage the maximum number of blooms.

  • thermometerTemperature

    Butterfly Bush is cold hardy and can generally withstand temperatures as low as 0°F and as high as 100°F. However, the ideal temperature range for the Butterfly Bush is between 60°F and 85°F. These shrubs may need some protection from extreme cold or frost, especially when young.

  • scissorsPruning

    Prune the Butterfly Bush in late winter or early spring to encourage new growth and a more compact habit. Cut back the entire plant to about 1 foot from the ground as it blooms on new wood. Pruning can be done annually, and it is also essential for preventing the plant from becoming too leggy and to promote vibrant blooms.

  • circleLife cycle

    Buddleja 'Miss Ruby', commonly known as Butterfly Bush, begins its life cycle with germination from seed, although commercial propagation is often through cuttings to maintain the cultivar's characteristics. Once rooted, the young plant enters a vegetative stage, characterized by rapid growth of foliage and the development of a robust root system. As it matures, typically within the first year, it enters the flowering stage during the summer months, producing vibrant pink-red flower spikes that attract butterflies and other pollinators. After pollination, seeds are produced and dispersed, although many cultivars, including 'Miss Ruby', are bred to be low or non-seed producing to prevent invasiveness. Following the flowering season, the plant enters a period of senescence in the fall where it begins to go dormant, with leaves turning yellow and dropping. Finally, in winter, the Butterfly Bush remains dormant, with the woody structure of the shrub surviving cold conditions to regrow the following spring.

      Early Spring

    • Buddleja 'Miss Ruby', also known as Butterfly Bush, is commonly propagated through softwood cuttings. This method is executed in late spring or early summer when new growth is mature enough to be cut but not fully hardened. A typical cutting is taken about 4-6 inches (10-15 cm) long and includes several sets of leaves. The bottom set of leaves is removed, and the cut end is often dipped in rooting hormone to increase the chances of success. The cutting is then inserted into a potting mix and kept moist and warm, with high humidity being beneficial for root development. Roots usually form within a few weeks, after which the new Butterfly Bush can be gradually acclimatized to outdoor conditions before being planted in the garden.
