Ophiopogon planiscapus 'Niger' is evergreen and is a plant that spreads through root shoots. It is a slow grower and not an aggressive soil covering plant and therefore well contained.
Characteristic are the sword-shaped, deep black purple leaves. The plant does not grow higher than fifteen to twenty centimeters. The leaf feels leathery due to the wax layer that is over it. In May - June the stems emerge from the heart of the plant with small, inconspicuous, lilac flowers.
More striking are the jet-black, shiny berries that stand on stems from July until the first night frost. They are the fertilized flowers. There is a kernel in the berry. If they want to be able to germinate, then first frost is necessary. A cold stimulus softens the flesh around the pit so that the pit can fall out freely. Birds can ensure its distribution. If you want to sow them yourself, the digestion process of the flesh can be speeded up by sowing the berries in a flowerpot or box on a mixture of sand and potting soil in equal proportions. Cover the seedling with a layer of sharp sand, but no thicker than two to three centimeters. Give the pot a place in the border to get through the winter. The winter cold does the rest.
