      Sort of. It's an American site so few of those are invasive in much of the UK.

              For me, crocus, euphoria Griffithii, most artemisias except Powys castle, many salvias, muscari, hedychium, houttynia to list a few are invasive.

                Hedychium invasive? Wow. I'd like them to do well. Which one please @Verdun?

                  Ha ha CarolineL :) I know it sounds odd.
                  Hedychiums enjoy our mild climate and simply grow and grow and grow. All of ‘em:noidea:
                  I grew several varieties....don’t get me wrong, they looked good, the scent was good etc., but the thick roots simply invaded spaces devoted to other plants. I did grow them in large containers too. Finally I removed them to a friend’s near 6 acre garden where they have now made huge clumps in beds devoted to them.
                  Next time I visit I will try to take a picture or two.:)

                    A few that we have currently.

                    An Iris (don't know its name but it has an orange flower. Been digging these out for the last 8 years and they still come back, even though I don't let them flower or seed.

                    longk's forget me nots. I'm forever digging these weeds out

                    Blackthorn. The main tree came down last year but the garden is full of saplings

                    Wild garlic. Some alium must've naturalised and a whole bed was choked with the bulbs. Five years later and I'm winning (I think)

                      In my garden poppies are hard to eradicate and some geraniums. For years I've been plagued by a hypericum which seeds everywhere and grows at an astonishing rate.
                      It's one of those shrubs I find creepy.

                        One of the most invasive plants of all. Beautiful but never knows when to stop. Erigeron karvinskianus. (Mexican Fleabane) It's like a flea in your ear, alright.

                            @andrews
                            Down here the wild garlic is being pushed out by Allium triquetrum.
                            Don't mention Allium sphaerpcephalon, a pretty thug, several yearsa after declaring war on it I still find the odd suspicious allium shoot.
                            As for other invasive plants Pheasents tail grass (Anemanthele lessioana), Job's Tears (Coix lachryma jobi), Haloragis erecta, feverfew all crop up regularly in numbers and I no longer grow them.

                                Yep, that’s one I discarded after one summer Nikalaos. Loved the foliage colour and took a risk :)
