Puksipensas

Puksipensas, the Finnish name for boxwood, refers to evergreen shrubs in the genus Buxus, most commonly Buxus sempervirens. It is valued in temperate gardens for its dense, slow-growing habit, small glossy leaves, and its ability to be pruned into formal hedges, borders, and topiary. It is native to parts of Europe and western Asia and is widely cultivated worldwide as an ornamental plant.

Puksipensas forms compact, rounded shrubs or can grow into small trees, with opposite, simple leaves about 1–2 cm long. The foliage remains green year-round, giving a consistent appearance in winter. Growth is slow to moderate, and many garden varieties stay relatively small, making it suitable for low hedges or clipped shapes.

Cultivation and care: puksipensas prefers well-drained soil with moderate fertility and can tolerate a range of light conditions from partial shade to full sun, though hot, exposed sites may require some afternoon shade. It benefits from regular watering during dry spells and protection from winter desiccation in exposed locations. Pruning is a key feature: the plant responds well to clipping and can be shaped into hedges, balls, or formal topiary. Prune after new growth flushes and avoid heavy pruning in winter.

Pests and diseases: boxwood blight caused by Cylindrocladium buxicola is a major concern and can defoliate and weaken plants. Other problems include boxwood mites, scale, and root rot in poorly drained soils. Good sanitation, adequate air circulation, and selecting resistant cultivars help mitigate risk.

Uses and varieties: numerous cultivars exist, including compact forms for low hedges and more vigorous types for tall screens. In climates with harsh winters, puksipensas is typically grown in sheltered locations or used in topiary and containers.
