Summer flowering seeds suggestions

I need advice from GCers please

I am after some summer flowering seeds which I can just sprinkle on the soil and let them do their thing. I saw Monty Don planting some last night and that was just what I needed to fill some gaps in my borders out front and also bring some summer colour because all the plants I have out there are spring flowering, plus I'd like to give the flying critters something to feast on

I quite like poppies but not sure how long they flower for and would like to have colour out there from say June to August - whether that is from different varieties of one flower or from different flowers I don't mind.

Colour scheme is pinks, yellows, reds and possibly some purples and oranges.

Nothing too exotic, nothing which will require staking and nothing which is going to require lots of maintenance - and they also need to be able to planted now.

Don't ask for much do I?

 

Hi

A easy one to grow and is not fussy are Calendula and hit the mark on most of the colours you are after (plus still time to sow)
Spruce

 

Funnily enough Spruce I have just been looking at Calendula Lemon Zest

I'm also looking at:

Eschscholzia Bridal Bouquet
Aster Bridesmaids
Poppy Lilac Pompom
Linum Charmer.

Don't want to go overboard so will pick three (buy two get one from from Suttons)

ETA : I went for some Stocks (cos I love the smell), Eschscholzia and Linum Charmer. Will see how I get on with those.

 

The T & M page below may give you a few ideas Merle....
I have just sown some Virginia Stock in a few patches around my front shrubs . I have never done very much direct sowing so I'll see how it goes.
