English Holly Ilex Aquifolium is a native plant species with very prickly, dark green leaves and gorgeous red berries. Holly is often used to give a deciduous mixed native hedge some evergreen content but it's also very popular as a classy single species hedge. Flowers December May producing red flowers. Grows 10 15cm per year. Supplied in 2 litre pots.Potted Plants are a more developed plant as their root systems are not disturbed during the lifting and planting process. They can be planted year round and if necessary can be left in their pots for several weeks before planting if you are unsure as to when you will be able to get round to doing the work all they need is a little water to keep them happy. As more mature plants you dont need quite as many per metre as the bare root plants normally 3 to 5 would suffice depending on how dense you require your hedge and how quickly you need it to look established. Pots are a great way to create a new hedge effect more quickly.
