The oval, bright green leaves have attractive creamy white centres a curious twisted growth habit that gives them a fascinating appearance. This RHS AGM variety makes a fabulous addition to borders, woodland gardens & patio containers, producing the best colour in a shady position. Supplied as bare roots. Height & spread: 45cm &40;18&34;&41;. Culinary information: The best part to use is the hoston, the rolled up leaf as it emerges in the spring. Cooking depends on the size of the hostons, small ones can be fried for a few minutes, going well in stir fries. Thicker ones are better boiled & used as a vegetable.
