corydalis intermedia/fumewort

[sunnyhills]

This plant has appeared in my shade bed . This plantheritage.files.wordpress.com/2012/03/dsc03774.jpg
is the best picture I can find of it to reproduce here .Tho I think mine is the more common intermedia type and has darker pink flowers .

I'm just wondering if it's invasive ? Shall I let it grow unchecked ,or be more careful ?

I have a blue corydalis in my garden which I have deliberately planted! I think they are lovely! It grows really well in my city - the yellow form - lutea - in particular, pops up in front gardens all over! So it does spread (via seed I think?) but it's not the worst offender by a long way - and I think it's native. Provided you don't mind removing the seedlings, which is really easy to do, it's quite easy to keep in check.

Thank you Holly - I love the way the leaves unfurl as it breaks through the soil .

Yes, it's got an attractive leaf as well as a good flower! It looks far more delicate than it is!

Ooh! I want this one!

I have corydalis lutea growing like weeds out of the stone walls here (let me know if anyone would like some seeds) but corydalis flexuosa doesn't grow, have spent a few quid finding out the hard way.
