The Ilex x Nellie R.Stevens is a holly plant that is a cross between English holly ilex aquifolium and Chinese holly ilex cornuta. The plant itself with its beautiful glossy green leaves and red berries has always been traditionally seen in Europe and America as Christmas holly and used in some European countries to ward off evil spirits by hanging them above the doorway. The flowering period is April where it usually starts to blossom its small white flowers and during the Autumn-Winter period, the actual berries themselves start to form. It is a bushy plant with a fast growth speed. It does not requiring maintenance but a quick trim in the summer could help if the leaves get a bit too long. The hardiness of this plant at H6 is perfect for the British climate and only during the extreme cold do you need to shelter it. Be careful of pests and potentially the holly leaf disease with this plant. The maximum height of this plant is between 1.5 m – 3 m (4.9 ft – 9.8 ft) and the eventual spread is between 1.5 m – 4 m (4.9 ft – 13.12 ft). Be careful not to eat the berries, no matter how inviting they may seem, as they could cause potentially a minor stomach upset if ingested.
