Imperial Lemon

A strong growing plant with heavenly scented white flowers throughout the summer with large lemon/grapefruit fruits. As this is grown as an espalier, it is perfect against a south- or south-west facing wall. It is sensitive to cold, so will need protecting in winter, either by moving it to a frost-free place or by covering the plant with horticultural fleece.
In the past, espaliers were mainly used in gardens where it was possible to shelter the plants in a lemon house. However, it is still the most suitable way to grow them against a wall or in a limited space, either in the ground or in a pot.
