Japanese laurel Aucuba japonica 'Mr Goldstrike' (m/v)
ABOUT
Aucuba japonica 'Mr Goldstrike', often simply referred to as Japanese laurel, is a distinctive ornamental shrub with a striking appearance that stands out in garden spaces. The plant has an evergreen nature, maintaining its presence throughout the seasons. The most notable characteristic of 'Mr Goldstrike' is its glossy, leathery leaves with a unique variegation pattern. Each leaf features a deep green background that is liberally splashed with yellow to golden spots and blotches, creating an eye-catching speckled effect. This variegation gives the appearance that the leaves have been spray-painted with gold paint, lending the plant its common prefix 'Mr Goldstrike'. Leaves of the Japanese laurel are broad and elongated, with a somewhat wavy or undulating margin, adding a textural dimension to the plant's overall look. Their arrangement on the stems is opposite, which means the leaves grow in pairs directly across from each other along the branch. During certain times of the year, the plant may produce small purple to red berries. These berries typically add another layer of interest to the shrub's appearance, offering a contrast against the variegated foliage. It is worth noting that 'Mr Goldstrike' can adapt to a range of lighting conditions, though its leaf coloration may be most vivid when the plant gets adequate light. Its ability to maintain an attractive appearance with minimal care makes it a beloved choice among gardeners looking for ornamental plants that offer year-round visual interest.

- Life cycle
Aucuba japonica 'Mr Goldstrike', commonly known as Gold Dust Aucuba, begins its life cycle when seeds germinate in moist, well-drained soil, under shady conditions. After sprouting, the seedling stage involves the establishment of a root system and the development of a few initial leaves. As the plant enters the vegetative stage, it grows steadily, producing its characteristic glossy, green leaves with gold speckling. In the reproductive stage, if a female variant of this dioecious species, it will develop small purple flowers in the spring, which, if pollinated by a male plant, will produce red berries in the fall. Throughout its life, the Gold Dust Aucuba requires minimal pruning but may be shaped to maintain a desirable size and form. This evergreen shrub can live for many years, and with appropriate care, it will continue to mature and thrive in partial to full shade gardens.
- Propogation
Propogation time
Spring-Early Summer
The Aucuba japonica 'Mr. Goldstrike', commonly known as Gold Dust Aucuba, is most effectively propagated through the method of semi-hardwood cuttings. This process involves taking a cutting from the plant during the late summer to early fall when the current year's growth has started to mature but is not yet fully hardened. The chosen cutting should be about 4 to 6 inches (10 to 15 centimeters) long, and its lower leaves should be removed. The cut end of the stem is then dipped in rooting hormone to encourage root development and planted in a well-draining soil mixture. The cutting should be kept moist and in a shaded location until roots have developed, after which it can be transplanted to a more permanent location.
