Description:
Dahlia 'Sarah' has deep dark purple foliage, and coral red flowers with a yellow centre.

Dahlias, as grown in the garden, are hybrids of plants originating from Central America. They tend to prefer free draining soils in full sun that are watered regularly.  Dahlias are late flowering, often into mid-November, providing a splash of colour when other plants are past their best. Their splash of colour does require work: not only do the taller varieties require staking, all require regular feeding and deadheading, and their tubers need to be lifted in the late autumn and stored.

Dahlia are classified into sixteen groups:
