Depends on what is in the mix, does it list the contents on the packet? Do you have seeds or plug plants or bulbs?

Landgirl's right, can't answer without knowing which varieties are present in the mix. Certainly, some alliums are highly invasive, but others aren't. If its a mix of bulbs, you usually find one invasive variety in there... but I'm thinking it can't be bulbs, because they should have been planted last autumn...

There are no details about the mix - it's the one advertised on this website.
I have planted Allium "Chameleon" and "Double Bubble".
Will I have a problem with either of those?
Which ones should I avoid?
My Bluebells have just about taken over everywhere!

Sadguna.

You say it's the mix advertised on this website. I'm not sure where you're seeing this...? I see no adverts at all, thank goodness.
