Crocosmia is easy to grow and maintenance free, flowering from mid to late summer in strong shades of red, orange and yellow. It is very reliable, a great border plant with lovely bold flowers in strong colours. Crocosmia is herbaceous, which means it flowers every year and dies back over the winter to bare earth, regrowing each spring. Crocosmia forms clumps with attractive sword shaped leaves and is long flowering.
Although one of the most common varieties, Crocosmia Lucifer is tall, up to a metre, other varieties are more suited for middle of the border being around 60-80cms, so you need to select the variety carefully ensure it is the correct height for where you want to plant it. Crocosmia makes a great addition to the border, being very easy to grow, possibly too easy as some varieties are vigorous, if not invasive, but to check growth just pull up and remove any unwanted spread. Crocosmia Lucifer, illustrated in the middle 2nd image, looks magnificent, and is a tall architectural plant, with strong red flowers.
Crocosmia 'lucifer' is illustrated below, it is a striking red colour and as a taller variety is is best given some support. Crocosmia originates from South Africa and flowers in all the sunrise colours with much variation in height; smallest varieties such as Jackanapes, and Canary Bird can be as small as 60cms (24") compared with Lucifer and Columbus 120 cms (48") and height is a factor as to where plants are placed in the border. Also some specialist varieties, often seen at plant fairs and shows, are very attractive but unfortunately not all are fully hardy. (explanation of frost hardy) Crocosmia make great cut flowers and as the clumps produce so many blooms there are plenty for the garden and the vase.
