Are there any flower seeds I can sow today that will do something this year?

I need to pad out some gaps and want to do it as cost effectively as possible.

Nasturtiums? You can eat them too!

I sowed the last of the nasturtium seeds this week. They're already up!

Or even quicker. Just buy some plug plants. Super cheap.

No guarantees this time of year, the light is already starting to reduce and annuals need a good blast of sun / UV and sufficient weeks to mature.

how big are the gaps? Could you look around the garden to see if there are any self seeded plants from previous years, then you have a head-start?

I’ve not long spent Lupins in the greenhouse, ready to plant out next year and one of the little darlings has a tiny flower appearing.
Not really answering the question, but you could get a head start on next year.
Garden centres are selling stuff off now.

Sowen , not spent!

Wallflowers. They won’t flower till next year but will give green coverage if that is all you need

You'd have to buy Wallflowers as plug plants or even better as bare-root from a farmshop or some garden centres - they are very slow-growing and wouldn't give any coverage for some months.

Linaria maroccana. They're little wonders - very fast to maturity (can be as quick as 6 weeks) and really pretty.

Nice choice, thanks for mentioning theses. I’ve got the common purple one, it self seeds beautifully. I’ll get some of these now.

On my local FB gardening group, I wanted some snapdragons to fill the gaps and one person answered and I got about 12 seedlings of around 6" tall, so hopefully, later in Sept. or so, they'll be flowering by then.
