Growing Guide

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. Protect your plant by growing it in a site that doesn’t experience cold winds. Fully hardy in the UK. Avoid moving these as they will struggle to be established when moved.


These thrive in rich moisture retentive soil, so they need to be regularly watered. However, as they struggle in boggy and wet conditions ensure that they’re not being over watered.


When the flowers and new foliage emerge is the best time to cut back the large leathery leaves. Ensure to mulch regularly on a yearly basis with well rotted compost or manure. Cut back the large leathery leaves when flowers and new foliage emerge and mulch plants annually with well rotted compost or manure.
