What does anyone think about plants that we buy in garden centres, that turn out to be unmerciful thugs ?
Should we not be warned, quite clearly with an "invasive" sticker ?
I am currently struggling with a reddish-coloured euphorbia whose progeny seem to be popping up everywhere.
Should we start a list of thugs to warn other forum users ? Question

I somewhat agree, however its complex territory - some plants will thrive and have a higher progeny rate given the optimal conditions

Additionally - lets put this way, if you were a grower selling plants, would you put "invasive" of "prolific seeder" on the label.... you may not sell as many plants....

The one thing they should put on labels ( and I think this is in the pipeline) is whether they are toxic / poisonous or not.

euphorbias secrete a milky substance that is a skin irritant to many people. also the herb ruta graveleons can cause a bad rash.

I have euphorbia, the purple kind and put it in the front border by the road for some purple color interest. Out of control plants that have runners are my biggest horrors, taking up too much gardening time to control and this year my hands and knees are packing in. Euonymous, lily of the valley, ivy and bishops weed are horrors. The second kind of invasive is the seed bearing burning bush shrub or violet that gets into the lawn, the former into anyplace behind your back and grows like a science fiction monster plant. The third is the one that never dies, even after an axe attack. Berberis or barbary falls into this category, as well as forsythia. The root go down to another country!

Saying all that, I have found some new cultivars for the barbary and what I hacked back, I'm now trying to propagate from cuttings. Strangely, this plant was banned for years because it escaped into the farmland and like the rhodo caused havok (in Canada) because it carried a rust which affected the wheat crops.

Plan of action: get a fancy ipad with an app that links to dave's garden and check everything before you buy. All plant dealers should know which plants they're selling and have a "do not sell list."

hi mountainy man, no, I don't think my euphorbia is the fireglow one you mention........ mine has dark purple-red leaves and acid green/yellow bracts, I'm not sure what it's called though.
And what a coincidence, that you mention your inula too.....would that be known as a perennial sunflower ? I planted one last year and already it is sending shoots up all over the place.... I'm going to take it out completely now...I hope I haven't made a big mistake bringing it into the garden at all.

hi sive
your euphorbis sounds like they might be amalgloides purpurea (not sure of spelling!) it is a bushy type i have a couple and have no problems with them . i think that the perenial sunflower is different to inula grandiflorum its helianthus something or other although its going mad like yours . mine i got as a root cutting a couple of years ago from a friend its now about 3 metres across , is beautifull tho, flowers all summer long

hi m.m. all the unwanted euphorbias may be my fault as I didn't dead-head it last year, so they may all have grown from seed. I'm sure if I had it somewhere else I'd be delighted with how it's spreading, but it's just a bit too prolific for my liking in a mixed border. Out it goes !
As for the perennial sunflower, I just hope I can get rid of that...it seems to spread by underground tubers.
i still think invasive plants should be labelled as such....but maybe with a less alarming word !

Would a George Bush be an invasive plant ? i think its extinct in the wild ! Laughing

sorry probably in bad taste!

stronger labeling is a good idea ,calling something vigerous doesnt do it for some plants ie, mint, persicaria, tansy, anenome.x hybrida, perriwinkle amongst others.
