Sowing and growing Biennial flowers

Biennials differ from annuals – which flower and set seed all in one growing season – in that they grow fast from seed and develop strong roots and foliage in one season, before flowering in the next.

For most, this means that they germinate and grow without flowering in summer and autumn, remaining dormant over winter, then

have another burst of growth before flowering in spring and early summer.

The classic biennials we all know are Foxgloves,wallflowers and Sweet William  but add to these Caraway,Dill,Parsley and Watercress to eat and Hesperis (Sweet Rocket) Honesty Poppies and Hollyhocks.

Of these the Caraway and Dill can be used in the even when they set seed the following year and can be grown happily in the flower border.

Sowing

Sow seed thinly into a fine tilth in a seed bed or individually into modules this is easy with most but tricky with the tiny seeds of foxgloves and poppies.Most will germinate in about 10 days.

Keep weed free and plant out into growing/flowering position in the Autumn.The exceptions to this are the Poppies and caraway which hate being moved so are best sown in modules or where you want then to grow.

Growing Biennial’s

Dont over feed and keeping them weed free are the main requirements for good growth.
