Description

Griselinia is a genus of evergreen shrubs and trees that are native to New Zealand, South America, and some Pacific islands. They are well-known for their glossy, leathery leaves that come in shades of green, yellow, and variegated forms. They can grow up to 15 meters tall and 5 meters wide, but most varieties are smaller and more compact. Griselinia is a popular choice for hedges, screens, and borders because of its dense foliage and tolerance to pruning.
