Hi all, Given 1. all the yammering I'be done over the years warning you about how nasty this weed is and 2. it so happens I am doing a convuvulacae growout test, and it includes some (so I have a sample to press and send to the ag extension, to confirm what the scientific name of the thing is) I though it only fair to pass on a photo, so anyone else who bumps into the thing will be forewarned and hence forearmed  It's the one near the center of the picture, with the lobed leaves |

What species is this? When I google the common name, your HG posts come up...  |

What species is this? When I google the common name, your HG posts come up... That's just it, I don't KNOW the species name, any more than I know the one of the long skinnly leaved non climbing one that makes the pretty yellow and black flowers. That's WHY I'm growing a plant to press and send to the ag extension, so they can tell me. I only know the common name because, way back when I did the first growout (years before I even came to this site) I did a google search on convuvulacae, and that was the name that came up on the one picture of a plant with similar looking leaves (whatever site that was, it's gone now, I know I looked for it) I know it probably grows in China (on the grounds that thats where the rice bean bags I find it in come from) but everything else is a blank) |

Hard to say, but it sure looks like domesticated (ornamental) morning glory. Possibly in Ipomoea family. Ipomoea nil? Japanese morning glory?

I did a little more digging on the web and here is what I have found
First, I think I should point out that the plants in the photo are quite small, there are in fact about 6-7 different ones in the frame, of varying types. all comments refer to the one near the top left, with the leaves with 3-5 lobes).
Second I did mamge to dig up two species that might fit the bill, one is ivy leaf morning glory, Ipomoea Hederacea , which does have lobed leaves (though no picture I have seen shows more than 3 and those seem to have "points" on the tips which this does not)
The second possibility is Ipomoea cairica. This one actually fits pretty well, as the leaves do in fact have 5 lobes (though again, they look a lot slimmer and pointier than mine ever got, plus mine the last time round often would get a lot more than even 5 lobes, sometimes as many as 20 (as the plant gets older and the leaves bigger, the number of lobes goes up, this one is only barely a seedling) The site mentions that one is native to asia (good sign) but is naturualized to a lot of warmish areas. The seed is supposed to be hairy, but the same process that cleans up the beans in processing also seems to strip any hair or velvet off convuvulus seed; they very rarely still have it by the time they get to me.)

The leaves on I. cairica look to me like palmate-compound-leaves, while blue's plant looks lobe-leaved. The Ipomea genus has lots of lobe-leaved species and they are rare in the rest of Convolvulaceae.

Yes I see you point about the carica being a little more deeply divided. It was just my best guess. There is actually a sort of relif in the fact no one has come up with an on the spot correct answer, it makes me feel like less of an idiot for not being able to identify it myself One other byproduct is the following, which is pretty close to the other unidetified ones appearance (the one I actually try to grow)  I seem to recall the flowers on mine being yellow and black (like those of a husk tomato) rather than white and red, but the plant could have multiple possible flower colors (actually if its' simply a lightness/darkness thing, then if those that have white margins had red throats, you might very well expect yellow margined ones to have throats that were a deep enough crimson to look black) I seem to recall mine being trumpet shaped as well, (not star) but these look like they might not be fully open, they could well be trumpets when they do. The leaves actually match very well (long, linear nearly sessile, side lobes modified into something almost like a sheath) as does the lack of climber (unfortunately this is the ONE convuvulus I found on the site they couldn't identify, so I'm no closer to a name. |

I detest morning glory. We have white, blue, deep purple, light purple, and pink. Annoying as they are they don't compare with the beautiful glyphosate resistant weeds going nuts everywhere.

How do/does Bindweed (MorningGlory) spread?
I have it where I never had it before dozens of feet apart in gardens/yards fifty miles apart.

It spreads both by seed and by root.

And by stealth and malign intent.

UPDATE: The mysterious vine has now reached the point where it has developed the furry nodules it gets instead of flowers  I know these look sort of like buds, but trust me, no flower will ever come out of them. At the end of the year the nodules will brown up and when dissected there will be 3-8 seeds of typical bindweed appearance. |

At the end of the year the nodules will brown up and when dissected there will be 3-8 seeds of typical bindweed appearance. You're seeing the base of what was a flower a day or two before. They then produce a seed capsule which does indeed last to the end of the year. I have the ivy leaf one growing here. No idea where it came from but just showed up about 10 years ago. I allow a few to grow every year. Martin |

Martin If this was a normal bindweed you would be right, but trust me on this, this paricular species NEVER makes flowers (visible ones, at least) by now the plant has indeed largely made it's capsules, but at no point were visible flowers present (I might think it was a night flowerer, but it isn't that either(if it was I'd find petal fragments on the ground in the morning). Actually tecnically that isn't a flower bud either, it's a group of buds (the plants do on occasion make single buds, but rarely, and those usually abort). Each of those lumps is a complex of 5 or so flowers (based on a count of seed pods). if you take one apart it's moslty bracts but there will be a small number of tiny hairy brown bits (which I suspect are the actual petals) eventually typical convulvulus pods appear (about the size and shape of mistletoe berries, so acutually a little smaller than typical ones) , still completely covered by the bracts. In a few weeks, when the pods are ripe enogh I can pick one and still be able to keep the seeds, I'll try and remember to take a scan of the thing dissected, so you know what I am talking about. |
