Sweet Williams are short-lived perennials but I prefer to grow them as biennials so I sow fresh seed each late spring/early summer so that they will flower the following spring.

Clusters of fragrant and rich coloured , these sweet Williams will bloom from mid-spring onwards.  Easy to grow, these fabulous traditional cottage garden plants also make wonderful cut flowers.
