Growbar Confetti Bar. This trio of English country garden flowers have been chosen for their dazzling colour, delicate petal shapes and ease with which they may be grown and dried to create gorgeous confetti that will float beautifully through the air.

Start by unwrapping your Growbar and place it with the brown protective paper facing upwards, into a container with plenty of space to allow it to expand; a takeaway food tray is ideal. Gently pour half a litre of water into the tray and position indoors on a warm, bright sunny windowsill. The seeds will need to be a cosy 18°-22° to germinate.

Water regularly and ensure the Growbar is perfectly moist, it should remain the colour of a rich dark ginger cake.

After a few weeks you should have a bar neatly dotted with little seedlings. These will be happy growing together in the bar for a further month in their sunny location.

When the seedlings have produced 4-8 leaves you may then gently separate them, being careful to not damage the delicate roots, and plant them in individual pots or a sunny weed-free spot in the garden. Plants grown in the ground with plenty of space and sunlight will produce more abundant fragrant foliage but it is possible to grow the seedlings in large containers on the balcony or patio.

How to identify your seedlings:

Clary seedlings have oval-shaped and softly hairy leaves. Clary prefers to be in full sunlight in moist but well drained soil.

Cornflower seedlings have long, slightly silvery leaves. Cornflower likes moist soil during spring and summer which helps prolong flowering. Dead flower heads can be removed to encourage flowering in autumn.

Larkspur seedlings have small feathery leaves. Larkspur like to be kept in well-drained soil in full sun. The stems like to be supported so stake well and keep sheltered from strong winds. Remove dead flowers and cut down in autumn.
