Corydalis Lutea

This is so pretty..
How tall is this plant, please ?
Does the foliage on this one disappear over winter ?

It's about 30cm high and mound forming. It is just about evergreen, This one is under my vibernum and did have foliage thoughout winter. One word of caution, it self seeds a huge amount and seems to pop up in every shady spot it can find! It is great though for filling spaces where other plants refuse to tread!

Thanks for the info. :o).
