Can anyone name this annual?

We bought these many years ago from the shop at Monet's garden and have been saving the seed ever since.

The foliage in the picture is the forsythia behind it!

Any ideas on name?

It looks like Coreopsis.

I'd agree, coreopsis.

Seed deteriorates over time, so if you have old seed I'd sow it!

I’m sowing last year’s seed - we’ve been collecting + resowing for over 20 years now, but without a clue to the name!

Coreopsis looks exactly right - thank you!

I am jealous, I can never get coreopsis to survive. Gorgeous plant.

That’s not a Forsythia behind it, wrong leaves. Looks like a winter jasmine.

You’re right @MereDintofPandiculation - my brain just went ‘early yellow flowers - must be forsythia!’
