Dicentra

[Chipchopper]

I have one dicentra spectabilis (bleeding heart) in my garden which I planted last year, it seems to be growing well and I'm hoping it will self-seed and form a drift in the flower bed.
Anyone had any luck with increasing this plant ?

Haven't grown it myself but my book of wisdom doesn't mention anything about self-seeding.Split established clumps late autmn\winter or for brittle rooted varieties (of which Spectabillis is one) take root cuttings in early Spring.

It's a hardy perennial, not an annual, so self seeding will not occur.
Leave it be, it will get better year by year.

I did have two but lost one this winter, possibly down to the wet weather. They had both been in for years and although they did get a bit bigger they hadn't 'spread' as such. I think you need to buy or try to propagate them yourself to get more plants I don't think it's going to do it by itself.

I have had a white dicentra in the border for 4 years now and although it is more established and gets more foliage and flowers each year, as the others have said, doesn't really spread as such:

It's a lovely plant however :-)

I have lost both of mine over this winter. As others have said, they previously 'filled out' but did not spread.

Thank you all for your answers!
I think I'll avoid the risk of root disturbance to my one plant, and instead collect some seed once the pods have dried.
With luck I'll have some seedlings in my cold-frame ready to plant out next spring :-)
