  • circleLife cycle

    Buddleja davidii 'Southcombe Splendour', commonly known as Butterfly Bush, begins its life cycle when its seeds germinate in warm, moist soil, usually in spring. The seedlings grow into young plants, establishing a root system and foliage through the vegetative stage in their first year. During the second year and each following summer, Butterfly Bush enters the reproductive stage, producing spikes of fragrant, colorful flowers that attract butterflies and other pollinators. After pollination, the flowers mature into seed capsules, which eventually open to release seeds for dispersal, and the cycle repeats. As a perennial plant, Butterfly Bush dies back to the ground in colder climates during winter, but regrows from its rootstock in the spring. With proper care and maintenance, it can live and flourish for several years, though it might be considered invasive in some regions, spreading prolifically if not controlled.

      Spring to Summer

    • The most popular method of propagating Buddleja davidii 'Southcombe Splendour', commonly known as Butterfly Bush, is through semi-hardwood cuttings. This process typically begins in the late summer. To propagate, a gardener would cut a length of stem about 4 to 6 inches (10 to 15 centimeters) from the tip of a healthy branch, ensuring that each cutting has several nodes. Leaves near the base are removed, and the cut end is often dipped in rooting hormone to encourage root growth. The cutting is then planted in a well-draining soil mix and kept moist until roots form, which usually takes a few weeks to a couple of months. During this time, maintaining high humidity around the cutting can improve success rates, which can be accomplished by loosely covering the cutting with a plastic bag or placing it in a propagator.
