This outstanding range of handpicked seeds are perfect for enjoying in the garden or in the home. This range includes show-stopping flowers and elegant floral fillers ideal for a bouquet.
One of the most nostalgic of wildflowers, cornflowers immediately evoke summer meadows from days gone by and romantic cottage gardens. 'Blue Boy' is a tall variety, featuring masses of double, bright blue flowers held on slender stems. It's perfect for mini-meadow schemes grown with poppies and ox-eye daisies, running through borders alongside calendula or sown into the cutting garden. With deadheading, it will produce flowers in abundance for many weeks.
Height: 1.2m (47"). Spread: 30cm (12”).
1 Packet (400 Seeds) (KC9721)
Sow cornflower seeds outdoors where they are to grow from March to April. Choose a position in full sun on well drained soil which has been raked to a fine tilth. Sow seeds thinly, at a depth of 3mm (1/8") in drills spaced 30cm (12") apart. Water the ground regularly, especially during dry periods. Germination usually takes 14-21days. When cornflower seedlings are large enough to handle, thin them out to 15cm (6") apart.
Alternatively, grow cornflowers indoors from August to September for early summer flowering next year. Sow cornflowers on the surface of a good quality seed compost at a temperature of 18-23C (65-73F) and cover with a very fine sprinkling of compost or vermiculite. Do not exclude light as this helps germination. When seedlings are large enough to handle, transplant and grow them on in cooler conditions until large enough to move outdoors. Overwinter cornflowers plants in cool, light, frost-free conditions before planting out the following spring, or growing on as greenhouse pot plants.

Thompson & Morgan strives to ensure that all its plants are delivered to you in the perfect condition for planting. While the majority of our nursery plants cope well with slight delays in intransit, sadly, the time it takes to deliver to certain locations in the UK means that we can't guarantee this for some of our smaller plug products and tender bedding and vegetable lines, which do not respond well to the extra journey time. So regretfully while we offer the majority of our live plant offering nationwide, we are unable to ship plugs, begging plants and tender vegetable plants to the following areas: HS, IV41-IV49, IV51, IV55-56, KW15-KW17, PA34, PA41-48, PA60-PA78, PA80, PH40-PH44, TR21-TR24, ZE1-ZE3
