Cosmos Razzmatazz gives a colourful display all summer long and has pretty semi-double flowers with shades from violet and lilac pink to pink blush and white, above its typical feathery-like foliage.
A taller and newer variety of Dicentra growing to a height of up to 75cm, ‘Valentine’ has heart-shaped cherry red flowers and dark grey-green foliage with maroon coloured graceful stems giving a wonderful contrast.
