Fast-growing plants

The fastest-growing plants include willow, poplar, bamboo, clematis, honeysuckle, and annual climbers like runner bean. They can add tens of centimetres, sometimes a full metre, in a season. They give quick screening but usually need more frequent pruning and watering.

The fastest-growing hedges are arborvitae, privet, hornbeam and cherry laurel — typically adding 30–50 cm a year. They form a solid screen within a few seasons but need regular clipping so they don't go bare at the base. For a very fast, seasonal screen, climbers on a trellis also work well.

Often yes — fast growth means more frequent pruning, more water and nutrients, and a risk of spreading beyond its allotted space. Some, like bamboo or certain willows, can be invasive and need a root barrier. Choose the species to match the space you have and the time you can spend on care.
