MG and SP won't take over?

editornj(7 Coastal NJ)April 30, 2009

Hi,

A worker at my local nursery said that morning glories and sweet peas won't reseed and take over, since they aren't hardy to my zone. Do you think I can plant my seeds without worry?

Thanks.

The degree to which the Ipomoea will successfully sprout from self-resowing depends on the exact species...

Ipoomoea batatas and Ipomoea tricolor will not survive , but Ipomoea purpurea will...

Ipomoea nil is also not usually problematic in NJ...

Hope that helps...

regards,

Ron

Morning glory reseed themselves and come back on me......nasty little weeds they are. I havn't planted them for three years, but have a ton of them every year now--they just won't quit.

Hi sophie12 - Could you share with all of us interested people which of the many different species that you have (?)...

Do you have flowers that look like the Japanese style Ipomoea nil cultivars that I linked to for easy reference...were you able to look through the PlantFiles at the many different cultivars (?)...

Do you know how to tell the difference between the 100's of different species (?)...

Do you want to post closeup photos of what you have as I can often ID the species from good photos...

The Term "Morning Glory" is an extremely general term that could potentially refer to any of several thousand different species and all with very , very different habits...and over-generalizations can be very misleading...

If you like Morning Glories , but don't like invasiveness , then it would Open Your Eyes to Learn about the Many Different Species and Cultivars which Are Not Invasive...

Please clarify...

TTY,...

Thanks, Ron,

I also have Cypress Vine (ipomoea pennata). Wonder if this would be problematic? TIA.

Ipomoea pennata is the old synonym for the current legitimate binomial of Ipomoea quamoclit.

Ipomoea quamoclit does re-seed and can come back prolifically depending on climate and the local conditions as present in a particular growing area...e.g., if the soil is well tilled , the seeds will more easily sprout...

Ipomoea quamoclit has not been problematic for me...and I find that the finely divided foliage allows light to pass through the finely dissected leaves to get to any other plants that it may be growing on or with...a plus from my perspective...

Ipomoea sloteri
http://davesgarden.com/guides/pf/adv_search.php?searcher%5Bcommon%5D=&searcher%5Bfamily%5D=&searcher%5Bgenus%5D=Ipomoea&searcher%5Bspecies%5D=sloteri&searcher%5Bcultivar%5D=&searcher%5Bhybridizer%5D=&searcher%5Bgrex%5D=&search_prefs%5Bblank_cultivar%5D=&search_prefs%5Bsort_by%5D=genus&images_prefs=with&Search=Search
is a hybrid of I.quamoclit and I.coccinea having leaves with larger lobes

The longer a species is grown in a particular climate , the more adapted to that climate the particular strain becomes...i.e., plants grown in Florida for several or many generations would become progressively better adapted to Florida than to Maine...plants that have successfully grown in Maine become better adapted to regrowing in Maine...

There are reports of Ipomoea quamoclit being 'invasive' up to a zone 5 , but seeds collected from plants that have become adapted to a very warm climate are likely to be less troublesome in a colder climate because the seeds will be less likely to survive the cold damp conditions of early Northern Springs...

I'd like to suggest for additional consideration the following species :

Moonvines

Ipomoea alba
http://davesgarden.com/guides/pf/adv_search.php?searcher%5Bcommon%5D=&searcher%5Bfamily%5D=&searcher%5Bgenus%5D=Ipomoea&searcher%5Bspecies%5D=alba&searcher%5Bcultivar%5D=&searcher%5Bhybridizer%5D=&searcher%5Bgrex%5D=&search_prefs%5Bblank_cultivar%5D=&search_prefs%5Bsort_by%5D=genus&images_prefs=with&Search=Search

Ipomoea macrorhiza
http://davesgarden.com/guides/pf/showimage/65128/

Ipomoea turbinata
http://davesgarden.com/guides/pf/showimage/54954/

Ipomoea carnea - an upright bush form in pink,lavender and white
http://davesgarden.com/guides/pf/showimage/12125/

Ipomoea lindheimeri - A native warm zone caudex forming perennial
http://davesgarden.com/guides/pf/showimage/127323/

Ipomoea pandurata - cold hardy perennial - does not spread invasively by roots or by seeds...
http://davesgarden.com/guides/pf/showimage/207097/

Ipomoea setosa - perennial in very warm zones only
http://davesgarden.com/guides/pf/showimage/86512/

Hope that helps...

Thanks, Ron,

That was very helpful. Now, if only I could *find* Ipomoea pandurata. ;)

These are the seeds I have.

I also have Star of Yelta, but have decided not to open that package, thanks to your advice.

Many, many thanks.

Hey Ron wish I could give you a pic of the MG's, but they never impressed me, so didn't take a picture of them, but...I do still have the seed package---Burpee Seed, Morning Glory, Early Call Mix. Just looked and there are several comming up again this year.

editornj - I notice that you are obtaining some Convolvulus tricolor in addition to some Ipomoea tricolor...

The Ipomoea tricolor (which is native to tropical America) rarely (if ever) comes back in force where there is alternating warm and very cold re-freezes in the Spring because this species has rarely adapted to successfully re-sowing in relatively cold climates...the seeds take up water and burst when it gets cold again...

The Convolvulus tricolor is native to the Mediterranean area and the desrts can get cold at night despite being warm in the daytime...

Convolvulus tricolor may come back in NJ from seeds...it's up to you as to whether you want to take a chance or not

Hi sophie12 - The Early Call mixes are likely to be either Ipomoea nil and / or Ipomoea purpurea...

The Early Call of yesteryear was almost always a nice selection of japanese style Ipomoea nil...but as these are relatively expensive the Early Call has gradually progressed more and more to contain more relatively common I.purpurea and in many instances is all I.purpurea...despite some misleading packet pictorials...

There are some I.nil that have adapted to cooler climates and can successfully self re-sow , but the flowers are usually smaller than the larger type fancier japanese types...

You most likely have I.purpurea that is coming back on it's own...

The Ipomoea tricolor would likely be a good candidate for you if you like the way they look...e.g., Flying Saucers","Pearly Gates" and "Blue Star" often look great growing together...just a suggestion...

Hope that helps...

TTY,...

Ron
