Crocosmia matthewsiana is a corm-forming 

 in the iris family Iridaceae, notable for producing arching spikes of red and orange flowers. It develops from basal underground corms that form vertical chains, a trait that affects both 

 and control. Flowering in the UK occurs from July to September. The corm chains are fragile and can separate easily, which influences how it is divided and moved.

Crocosmia matthewsiana belongs to the iris family Iridaceae and follows the growth habit typical of its genus, arising from a series of basal corms. The wider group originates from grassland regions of southern and eastern Africa. Plants set alternate, sessile blooms on horizontally branched flowering stems and in the UK flower from July to September. Plants grow from stacked corms that renew annually; the youngest corms sit at the top of the chain while older, larger corms lie deeper in the soil. Those chains are fragile and separate readily, so careful lifting and division is the principal method both for propagation and for keeping clumps in check. Contractile roots on lower corms can pull bulbs down to a stable depth over time. Where space and presence of tall spikes are wanted, use Crocosmia matthewsiana where the arching flowers can be shown off — for example in mixed herbaceous borders or against a backdrop that supports its stems. Because of the ease with which corms divide, plan for occasional division to prevent unwanted spread and to renew vigour; note that the flowering season in the UK runs from July to September, which is the reliable window for inspecting and dividing corm chains.

Crocosmia matthewsiana (montbretia) produces red and orange flower spikes in the UK from July to September.
