Holly a shrub that has pointy leaves and structural shape that can be attractive all year long. They prefer well-drained but not dry, slightly acidic soil in full sun; but most can tolerate unideal locations and will grow well in partial shade. Red berries appear on female plants only (holly berries are poisonous to pets and humans). Holly bushes can range from small low growing shrubs to large trees, but most usually get 6-8ft tall and wide. There are many varieties that have rounded leaves and are a wonderful addition to any garden.
