Californian poppies will flower extensively producing a bright number of single flowers in an array of cheerful colours. These wonderful sun-loving plants are easy to grow and will add a vivid splash to your garden throughout summer. They're a hardy annual, flowering the same year. Growing only 40cm tall they make a great flower for borders, rockeries, or planted in clusters in pots. Pick when the blooms are tightly shut to make a lasting cut flower for indoor displays.
