These stunning, easy-to-grow and extremely rewarding hardy annuals are a favourite of butterflies and me!   

They have a quick growth rate and produce an abundance of double pincushion flowers that are around 50mm across and sit atop tall, sturdy stalks. They bloom from the middle of summer to the beginning of autumn, adding a touch of sophistication to your border while also providing you with some excellent cut flowers.

This variety is beautiful and dramatic with extremely deep purple flower heads, some of which have exquisite white stigmas that contrast with the dark purple; some of the flowers actually do appear to be black.
