Took some more pictures, this time of the seed/flower things.
(In other news, how do people take pictures with cellphones??? We have an old one that we use for pictures, and I can't keep the dratted thing steady. I'm used to holding a camera against my face and looking through a viewfinder. My face acts almost like a camera stand, helping stabilizing the camera. But, I can't keep a cellphone stable when I have to hold it arms-length to be able to see the screen, and I have to push a button on the screen to take the picture. I miss my viewfinder!!!)
Its evil. Keep on top of it and don't let it set seed or you'll be fighting it for a long long time.
"The rule of no realm is mine. But all worthy things that are in peril as the world now stands, these are my care. And for my part, I shall not wholly fail in my task if anything that passes through this night can still grow fairer or bear fruit and flower again in days to come. For I too am a steward. Did you not know?" Gandolf
Yikes - sure looks like bindweed to me too - there are several varieties of it. As Marco said - DO NOT let it flower and go to seed. DO NOT yank it out of the ground because that will just stimulate the deep and meandering roots to multiply.
My only encounter with it here on the east coast was in a densely planted flower garden. The homeowner had been yanking it up every year, thinking it was morning glory. So after much googling I decided to smother it and use (shhh - don't tell Paul Wheaton - it was before I discovered permies!) r------p very selectively. I cut off the end of the vine leaving 12-18", coiled that into a ball close to the ground, and painted it with a small sponge brush. Covered that with thick cardboard and wood mulch. That pretty much controlled it for the two years I worked there, with occasional new sprouts coming up in random areas around the half acre yard.
Many similarities to : the rarer Copse Bindweed (Fallopia dumentorum) which grows up to three times longer at 3m, but the tepals have a wider white margin.
Varieties : (Calstegia convolvulus var. subalatum)
Slight resemblance to : Russian Vine (Fallopia baldschuanica) but that grows to 10m or more climbing vigorously over anything upon which it can obtain purchase, but the flowers are white, plentiful and in showy trusses.
No relation to : Calystegia genus Bindweeds such as Hedge Bindweed (Calstegia sepium) , Large Bindweed (Calstegia silvatica) , Hairy Bindweed (Calstegia pulchra) or Sea Bindweed (Calstegia soldanella) [plants with similar names].
Not a true Bindweed such as those belonging to the Convolvulaceae family like Sea Bindweed (Calstegia soldanella) and others belonging to the Calstegia genus, but has similar Ace-of-Spade shaped leaves, and can also climb, but it also sprawls if it finds nothing to clamber up. Fruit a small dull-black triangular nut on a very short 2mm stalk.
Black Bindweed is a Metallophyte with the potential to absorb 280ppm by weight of copper via the fine roots.
Three previously unknown flavonoids have been isolated from Black Bindweed, Falloconvalin A, Falloconvalin B and Quercetin-3-O-(2-E-sinapoxyl)-glucopyranoside.
Edible parts of Black Bindweed: Seed - ground into a powder and used as a gruel or mixed with cereals. The seed coat should be removed before use, this has caused mechanical injury to the digestive systems of animals who have eaten the seed. The seed is rather small and fiddly to utilize.
I'm not about to try fiddling with the seeds, so I'll be weeding and destroying this one. It was only in one part of my garden last year, and now it's in at least three places. I don't need it in even more places!!!
Interesting! I kind of went crazy planting a lot of traditional medicine plants only to discover how invasive and time consuming to process they are (just pruned my prickly horehound today) It's tempting to try to become a medicine woman but not likely in my "spare time" so I can imagine with two youngsters you sure don't need more stuff to fiddle with :)
