invasive ?

I love morning glories, but I understand that some of them are considered invasive in my zone. Is there an easy way to distinguish between those which are "invasive" and those which are not? I ask because I have accumulated several different types of seeds through purchase, seed swaps, etc. and I want to try to be environmentally responsible ...

There`s tons of good info in there so make you a cup of tea and enjoy!

Gardener2005, you are hot and thank you.

LOL - thanks for the link. Full cuppa Coffee here, dog lying at my side... I'm ready to dive in.

There is no 'easy' way to tell the behavior of a plant except by experience and knowing a plants habits

Here's an abbreviated reference list that might be useful
some types rarely produce seeds e.g., clones or some double types),roots won't survive or you can stick with bonafide US native MG's

Calystegia sepium - a bonafide US native and is invasive to cultivated areas
Calystegia spithamaea - bonafide US native spreads by rhizomes,but stays relatively low and twines little
Convolvulus cneorum - most are clones and won't produce any seeds
Convolvulus sabatius - most are clobnes and non-seed producing
Evolvulus arizonicus - bonafide US native
Evolvulus glomeratus - clonal and non-seed producing
Evolvulus nuttallianus - bonafide US native
Hewittia sp - seeds won't survive freezing
Jacquemontia pringlei - bonafide US native
Ipomoea alba - seeds won't survive freezing
Ipomoea adenioides - won't survive freezing
Ipomoea barbatisepala - A US native plant
Ipomoea batatas - rarely produces seeds
Ipomoea carnea - a shrub or tree - doesn't twine around anything
Ipomoea cardiophylla - bonafide US native
Ipomoea imperati - bonafide US native won't survive freezing
Ipomoea lacunosa - bonafide US native but reseeds alot
Ipomoea leptophylla - A US native
Ipomoea lindheimeri - A US native
Ipomoea longifolia - bonafide US native
Ipomoea macrorhiza - won't survive freezing
Ipomoea nil - many of the large flowered types will not produce a tremendous amount of seed and I.nil is sold in many stores
Ipomoea pes-caprae - won't survive freezing
Ipomoea pes-tigridis - not known to survive freezing
Ipomoea pandurata - A US native plant
Ipomoea platensis - won't survive freezing
Ipomoea purpurea - will reseed,but is already growing wild in many parts of the country...hurts the environment alot less than the exhaust from your car
Ipomoea sagittata - spreads by rhizomes but is a US native
Ipomoea setosa - seedpods large and easily gathered
Ipomoea ternifolia - bonafide US native
Ipomoea tricolor - seeds won't survive freezing...
Ipomoea turbinata - seeds won't survive freezing
Turbina corymbosa - seeds won't survive freezing

TTY,...

Oh, now that's a handy list. I'll print that and use that to mark up/toss my stash of seeds. Thanks, Ron.

... shoulda known that it wouldn't be 'easy'. :)
