Liven up your summer planting combinations with this unusual and distinctive plant Chasmanthe floribunda 'Saturnus', also known as African Flag. This perky plant is native to South Africa and rarely available in the UK, so by growing it you’ll certainly be making an intriguing talking point. It’s a fantastic addition to a hot, dry border and also a great coastal option. Similar to a crocosmia, but with added exotic charm, the remarkable, uniformly positioned orange blooms stand out like little flags from the stem.

Beautiful orange Chasmanthe floribunda 'Saturnus' is perfect for planting in mixed sunny borders or containers either on its own or combined with other drought-tolerant, sun-loving plants. It’ll need a bit of winter protection, but given the perfect spot, this perennial will grow back for bigger and better show each year. Plus, if you enjoy snipping your own fresh-cut flowers form the garden, this tropical looking treasure makes for a truly big and bold arrangement!
