When planted in the garden, Crambe cordifolia is an extremely deep rooted plant which does not like to be moved and possibly wouldn’t survive being transplanted elsewhere. As this is key to what is otherwise an extremely hardy plant’s wellbeing it needs to be well noted by anyone thinking of adding this unusual plant to their garden.
The Crambe cordifolia needs to be cut right back in the autumn, back to the ground and benefits from a generous application of fertile manure of composts around the plant during the spring in order to encourage new and continued growth.

Where to plant:

Crambe cordifolia works very well in a border, towards the back row due to its height and spread. The Crambe cordifolia  has delicate looking flowers which provide an intricate and interesting backdrop to a variety of different flowering plants.
The Crambe cordifolia can be planted either directly into soil or in large container tubs, dependant on the garden type of sun exposure, as this is another plant which prefers full sun. 

What to plant with:

How to propagate:
(Cuttings/Seeds etc) Crambe cordifolia can be sown very successfully from seed or via cuttings. Seeds can be sown directly into the garden in the spring or indoors from late autumn.
