Sisyrinchium striatum (what a name!)

I have some in a couple places around the garden. It's leaves do die back and go dark, I mainly leave them and just cut down the flower stems once the seeds are formed. Not had any problem with them spreading, one lot are by the pond and others in narrow boarder at side of house so they are in with other plants.

I found this winterwhite:

When the leaves die they go black and look very unslightly, especially in winter, but worse is the way it seeds. It is essential that you cut off the spent flower spikes as soon as the last flowers fade to prevent seeds being cast all over the garden.

I love it so, naturally, it wont grow in our garden.

kitty I’m like that with lily of the valley I’d love to have enough to pick bowlfuls inthe spring just like my grandma used to have. But never one has survived.

I’ve got some growing in semi shade, it’s the white albidium variety. Hasn’t spread so far. Lovely plant.

I have one, it's a new one never had it before, it's a pretty lemon coloured one .... so no idea if it is an invader?

I am growing mine in a container as I have no ground at all, so we will see what happens!

We had/ have it in the garden, after seeing it growing in a sort of gravel garden.
It is very pretty when in flower, but does look unsightly when the leaves turn black.
I have been pulling it up now, and am trying to get rid of it all.

I have an area with about 100 lily of the valleys in it increases every year

I cant grow those either.
