A popular garden cultivar with glossy, green leaves and distinctive red-purple stems. A shrub that wears its colour on its bones.
The stem colour is most intense in cooler months, when the red-purple tones deepen and become more pronounced. The leaves are oval-shaped, up to 8 centimetres long, with a smooth, shiny surface. They are arranged alternately along the stems. A plant that saves its best for winter.
The plant is a hardy, fast-growing shrub that makes excellent hedging. It tolerates clipping well and is ideal for coastal gardens, where its glossy leaves stand up to salt spray and wind. The red-purple stems provide winter interest when the leaves have fallen or been clipped back. A plant that makes a good fence.
Twilight Griselinia is a selected form of the native broadleaf (Griselinia littoralis), which is found throughout New Zealand. The parent species is a common coastal and lowland tree, but this cultivar was selected for its colourful stems.
The cultivar is named Twilight for the reddish glow of the stems, which can look like the light of dusk or dawn. It is also known as Red Stemmed Broadleaf. The stem colour is most pronounced on new growth, so regular pruning encourages the brightest colour.
To find Twilight Griselinia is to look in the gardens and hedges of New Zealand. It is a plant of cultivation, not of the wild.
The hedge is trimmed. The stems are red-purple, glowing in the winter light. The leaves are glossy, green against the dark. The shrub does not know it was selected for its colour. It does not know it has a name.
It just grows. That is what it was made to do.
