I love sowing some seeds and the last few years I’ve grown these amazing Cosmos flowers – just on my windowsill. I normally put two to three seeds per pot as not all germinate and you can then prick out and pot on the strongest seedlings.
If you want something dramatic and tall for your border which keeps on giving blooms from summer into late Autumn, then have a go at growing cosmos – you’ll not be disappointed! Oh do let me know how you got on if you grow any Cosmos. Happy gardening!
