Helleborus niger ‘Advent Star’ Growing Guide

An easy plant to grow – excellent planted in a decorative patio container for the first winter, either as a stand alone plant on a doorstep or in a cool porch, alternatively its pure white flowers can be used to brighten up a winter mixed container with other plants such as Heuchera, Grasses, Bulbs and Cyclamen.  It can then be planted in a border after flowering has finished.

This variety has been selected for its large pure crystal white flowers which are carried on strong, upright stems and borne above the foliage.  It is a particular early flowering form and most will produce flowers from mid-December (dependant on weather conditions).


Dig a hole at least twice the size of the rootball and loosen the sides, mix the soil with some soil improver such as compost, plant the rootball taking care to lightly cover all the compost without burying the crown, firm well and water thoroughly.  For the first year ensure the rootball doesn’t dry out whilst the plant establishes.
