What makes this variety special
Sweet william is one of the oldest plants found in cottage gardens, and this mix shows why: the plants vary in colour but share the same compact habit, hardiness and spicy, clove-like fragrance. The flower heads are usually 6–10 cm in diameter; in a good position, one plant produces a dozen or more flowering stems.
As a biennial, it forms only a rosette of leaves in its first season and flowers the following year. It is worth sowing it every year – that way, the garden always has one batch in bloom and another coming on. Self-seeded plants from the mix can produce surprising colours, which many gardeners find an added attraction.
Step-by-step cultivation
Sowing (May – June, under cover or in a seedbed): sow the seeds in rows in trays or directly into a seedbed, covering them with 3–5 mm of soil. At 16–18°C, seedlings emerge after about 2 weeks. Keep the substrate evenly moist, but not wet.
Thinning / pricking out: when the seedlings have 3–4 leaves, thin them (or prick them out) to about 10 × 10 cm spacing so they develop compact, strong rosettes. In summer, it is worth providing light shade in the hottest weather.
Planting out (August – September): plant the young rosettes in their permanent position at 30 × 30 cm spacing. Sweet william grows well in any average garden soil, provided it is not waterlogged; it responds well to liming. The plants overwinter outdoors without protection, but in harsher winters it is worth covering them with a thin layer of branches.
Care: feed with a balanced fertiliser in spring and water during dry periods. Removing faded flower heads prolongs flowering and often allows the plant to survive into the following season. Seed heads left on the plants produce self-seeding plants that can be transplanted like seedlings.
Uses
This mix is ideal for colourful cottage-style flower beds, borders and groups, naturalistic gardens and cut flowers – a bouquet of sweet williams in different colours is a summer table classic. It looks good with foxgloves, delphiniums, bellflowers and daisies. The flowers are popular with butterflies and bees.
Gardener’s tip
One gram of seeds produces one thousand plants – do not sow them all at once. Sow half in May and half in June, and leave the strongest seedlings when pricking out. Seal the remaining seeds tightly and store them in a cool place; sweet william retains its germination capacity for 3–4 years.
