Sow in August? Well yes…

Cornflower (l-r) 'Classic Fantastic', 'Classic Romantic' & 'Classic Magic'

Am I mad? I’m looking at my cornflowers in full bloom and I’m going to suggest it’s time to sow seed for next year. OK, here’s the thing.

I sowed my cornflowers towards the end of March, this year, and they’re flowering well now. I should also mention that I got my ‘Black Ball’ seed from someone else, not Mr F, and half of them came up other colours. Not good. We know what the lesson is. Anyway.

Although my cornflowers are flowering nicely, the ones that did really really well are over. These are the self sown ones that sprung up last summer from seed that fell from last year’s spring sown varieties.

The plants they made were huge, multibranched, producing thousands of flowers. But they turned up in all sorts of places, including in my bark paths. I know, I could have moved the seedlings to better sites – as I’m about to with my self sown cerinthes – but I forgot.

So I’m going to sow cornflowers this month. And, thinking about posies for next summer, I’m going to sow the three varieties in the Classic Series. These are controlled colour blends in blue shades and white (‘Classic Fantastic’), in purple and lilac shades and white (‘Classic Magic’), and red and pink shades and white (‘Classic Romantic’). Colour themed posies in a packet.

Sow in rows in a sunny place this month. Draw out the drill with the point of a stick then soak the drill with water from the spout of the can. Then sow thinly. Thin the seedlings in stages to 20-25cm apart and they’ll start to flower in late spring next year. The plants will be big, so have some bamboo canes and string at the ready. And stand back and admire your achievement!

Happy cornflower harmonies

Cornflower 'Classic Fantastic'

One of the easiest ways to ensure harmonious colour co-ordination in our borders is to choose plants whose flowers come in different shades of the same colour. Mahogany, gold, yellow and primrose, for example.

But it can take a lot of chasing round and picking varieties from different catalogue and nurseries to get the blend right. Fortunately, this spring sees the introduction of three rather cleverly formulated cornflower mixtures that do the choosing for you.

The Classic Series of cornflowers comes in three different colour formulations, all of which are made up of tallish plants reaching about 75cm in height, ideal both for borders and for cutting.

‘Classic Fantastic’ (above) comes in dark blue, mid blue, pale blue and a white with a blue eye. ‘Classic Magic’ comes in deep red shades, various pink tones and a white with a pink eye. In the ‘Classic Romantic’ blend the flowers are plummy purple, some almost black, dark purple with white tips to the petals, various purplish and lilac shades and white with a purple eye.

All three blends will look good sown in clumps between roses, especially between English Roses or long flowering shrub roses. Sow in a few short rows to create a patch to fill the space and thin the plants to about 15cm apart. Don’t thin too severely or you might end up with an unbalanced range of colours.

I’d be tempted to sow a few now, if you’ve got your borders all tidied, although I’d usually prefer to get the seed in by the end of September. Otherwise leave it till March. For cutting, a few rows of cornflowers can transform your veg garden. And the harmonious colouring is all there in the packet.
