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!
