Can I grow Crocosmia from last year's seeds, and how best to?
I bought a Crocosmia Babylon from my local garden centre towards the end of the season last year (so half price!), which had a couple of flower stalks on it. I've left it like that since (i.e. didn't dead head once the flowers died), and have just cut the dead stalks off and harvested the seeds.
Are these likely to grow if I plant them now, and what should I do to give them the best chance of success?

yes they should germinate and will take about 2-4 years to flower but as they are from a named variety they may not look anything like 'Babylon'. You may be lucky and get some lovely results.

It should be straightforward. They seed themselves here and I have to keep puling them out.

Yes! I have in the past with good results :o)) Mix soil with Perlite, Sow cosmos seeds undercover in March-April, or direct sow in May. Plant out seedlings once the frosts have passed in late May or June.
