Which seeds can I plant now and put on my windowsill?

[PosiePetal]

I have acquired a few little pots and have some grow bags left over from my gardening yesterday and would like to try to grow some flowers from seed. I have a south facing bay window over a radiator, it has 2 houseplants on it that both seem to thrive there.

My garden is made up of shrubs and herbaceous perennials, I am not really into bedding plants. I have a bit of a white and pink theme in the garden. I have lots of little pots on a patio area where I sit in summer so the seeds I grown could be planted into the flower beds or kept in pots on the patio.

I have never grown flowers from seed before despite being a keen gardener. What do you recommend I could try?

Sweet peas are easy and now is a great time to start them. Cosmos do well if you start them indoors too, and both are available in pinks and whites.

I planted some rather fabulous purple poppy seeds yesterday, and some lily of the valley corms for my shady border.

My first thought was Calendula/Pot Marigolds, easy to grow and do well in pots. They're annual but produce lots of easy to collect seeds.
They wouldn't fit with your color scheme though. so maybe dwarf cosmos. I love Cosmos and they come in beautiful colours to match your scheme. Dwarf for the pots or normal for the border.

Thanks everyone! I bought 6 packets of seeds yesterday including sweet peas, Cosmos, poppies, Calendula and wild cornflower. They are all now potted up and on the windowsill! I am so ridiculously excited about watching them all grow! I have never had the time or suitable location to do this before now (I am 53 and a keen gardener!).

Thank you all for your suggestions.

That's an excellent selection and exactly what I was going to suggest - mainly because they are all ones that don't get munched by slugs as soon as you plant them out!
