Emma - Nice collection of Photos...if you look very(!) closely can you see any(!) hairs anywhere on the stems,leaves or especially on any of the sepals(?)...the reason I ask is there are at least 2 different subvarieties of Ipomoea pandurata and I'm trying to see if there is a consistent correlation between the completely smooth(glabrous) types, hairy types and seed characteristics...
The vine appears to be more smooth, however, the leaves Front And Back, and the leaf stem are 'slightly' hairy. Actually the leaves feel soft to the touch, and with the 'OptiVisor' I was using, the leaves actually LOOK like Green Velvet.
No hairs on the sepals.
Looking at the Petals with these lenses --- they are very interesting!
They look like a textured fabric and they feel soft. Unlike any other MG petal that I've felt.
Emma - Thanks for the feedback(!)...Is there any possiblity that a combination of the Macro feature on your camera,angle and lighting might be able to render visible the hairs present in any photos(?)...
Emma how blessed you are!!!! I used to have this beautiful Ipomoea growing in my backyard and I miss it. At the time I knew nothing about it other than it returned faithfully year after year with lovely blooms. Then I had a privacy fence installed a few years ago and apparently the tuber was dug up or harmed in the process as it was growing on the fence line. I sure miss my Ipomoea pandurata!!!!
You reminded me to go look for this plant again. I saw it last summer and took a piece of vine and it died. I figured it was hard to root so didn't bother getting another piece. Now that yours is ok, I think I will try again. They grow along a road we take to town in a ditch.
Congratulations Emma! I know what a great feeling it is to FINALLY get a plant you've admired and wanted for so long.
The "Old Man of the Earth" grows along the road I live on and in and around my yard. We are pretty dry here in the summer so they have never been particularly eye-catching due to the few blooms they have produced.
This year, I have put an arch for one to climb on and have been seeing to it that it is watered regularly, hoping to see what one will do given proper care.
I should be seeing the first blooms open in a few days and there are many coming! It should be a great show.
Here is a picture of the vine on the arch (some sort of builder's material: a narrow ladder-like strip of soldered wire). Sorry the shot isn't clearer.
The I. Panduratas nearby have very tiny hairs all over both sides of the leaves and petioles. The leaves actually have a sort of sand-papery feel to them: not pleasantly soft like those of, say, "Velvet Leaf" or Marshmallow. Just rough.
Didn't notice if the sepals were hairy, but I'll check tomorrow. Don't have a better camera or macro (borrow this one from my brother) but I'll see if I can capture some detail for you.
Robert - Excellent shot of the sepals(!)...I wonder if you can zoom in any closer to show the differences of the ridges on the 3 different types of sepals
1)the 2 outer sepals - both outer side edges exposed - looks like 3 ridges with 2 grooves
2) the 2 inner sepals - both outer side edges overlapped - only 1 ridge(?)...any grooves(?)...
3)the 5th sepal with one edge overlapped and one outer edge exposed - similar to 2 outer sepals as shown on the left bud above
You will see a different leaf in this one that is not from this vine. It is 'one of those' vines that we have around here.
Oh, and Robert. Now I don't feel so bad. Looks like NC has plenty of bugs too, just like here in Texas. They sure do love these I. pandurata vine leaves. Look at all of the holes. Probably grasshoppers.
Yeah, those holes! I think the ones on my vine are caused by a tiny shiny black beetle that also loves to eat the petals off of purple coneflower before they even show color! They are sneaky too: they drop off the leaf or bloomed when disturbed so they're really hard to remove. Carbaryl gets 'em every time, but there's the bees and so forth to try and save, but I use it on the foliage and on the very small buds long before ther's anything to attract a butterfly or bee.
Great luck you're having with all the pandurata!
I dug up a small root the other day too. Pencil thick and about 7" long (I broke part of itoff, accidentally). Looks like it's going to be fine.
There used to be a lot more on the sides of the road I live on, but the county has done a lot of clearing recently and roadwork too and the areas are so disturbed and all sorts of "weeds" and things are springing up like mad that I'm not sure how they're doing this year. I'll have to go and check close up. As hardy as they are, I'm sure they'll come back and fight their way through any kind of mess to find the sun.
Where I see them it is a drop off ditch and no place to park. I will have to have my husband drop me off and take off if a car comes. It isn't a busy country road at all. Most of the locals prefer traffic, I guess.
I did go for a walk a couple years back on that road with a neighbor and came back with several ticks on my clothing. So, YUK! Look out for those.
I found this MG just this morning growing near my driveway. I couldn't get down the embankment to take pics- too many bees and too much poison oak. The leaves on the plants were COVERED and eaten by Japanese beetles. Also the vines are loaded with very "un-morning-glory-like" seed pods.
What a Beauty, and you didn't even have to go out and hunt one down!
Is there any way you can take photos for us [especially Ron] to see. Interesting that you say:
'the vines are loaded with very "un-morning-glory-like" seed pods'
Because, if yours really is I. pandurata, I would LOVE to have some of your seeds, if you can make it to them. I'm thinking that the plants in my area don't produce seeds, but time will tell, and I'd like very much to get another species started growing with what I have so I too can get seeds.
Robert, If you think you might be able to get one of your plants out for me, I'm POSITIVE, I will have something to send you in return, or at least pay for the postage.
Incredible photos. . .So vivid!
Wish my camera would do that.
Now, can't wait to hear what Ron has to say.
Do the stems have the same 'bristly' feel as the leaves(?)...
This photo here http://davesgarden.com/forums/fp.php?pid=2453342
shows what looks to be a yellowish 'woodrose' looking seedpod developing just under the right flower...Robert,can you confirm that the yellow structure visible in the above photo is a developing seedpod(?)...
berrygirl - if there is a certain day and/or time of day,along with appropriate protective clothing,that you or a very helpful friend can capture a photo of the unusual looking seedpods, that would be very helpful to the people who are very interested in this species...if there is aplenty of the pods,maybe you can quickly snip off a small section of the vine with some seedpods attached to photograph the seedpods indoors...
Do the seedpods on yours look like the yellowish structure visible in the picture posted above by radio(?)
Emma - do all of the vines that you have also have 'bristly' feeling hairs like Roberts(?)
Ipomoea pandurata is reportedly grows best in areas that do not experience prolonged wetness,as this causes the roots to rot and that is what happened to the ones I had planted in my yard...the plants were doing good in 2 gallon containers,but when I planted them directly in the ground here,the roots decayed...as the ground water level here is very high all year round...same thing happened to the Ipomoea leptophylla I had growing here...
Keep the info flowing...
P.S. - soil that has a high clay content may contribute to the health of the plants as the clay affects the balance of electrically charged/ionized nutrient cation adsorbtion/absorbtion and also affects the way moisture is retained or 'repelled' from around the root environment...
Thanks for the planting information on the I. pandurata.
I just potted up the two small tubers I got this week, so I'd better remove them from that potting soil and go ahead and plant them in the very back of my property where I planted the others. In fact, this soil is very sandy and has not been amended at all, which is probably why the tubers are loving it there that we just planted.
Also, 'moko' in Arkansas was kind enough to send me three of his tubers [that do produce seeds] a couple of months ago, but I'm sorry to say they didn't make it, so I must contribute that to the fact that I also planted the tubers in regular potting soil.
I checked the stems of the pandurata here and it is a bit "bristly", not so much on the newest growth, but seems to develope as they mature. The stems closest to the ground are quite rough now, though not prickly. The "bristliness" also seems as if it is in a linear form, that is, it isn't evenly placed around the stem but seems to be in lines and those not necessarilly consistant in texture along the length of the stem between the nodes.
Hope that helps.
I guess since we're finding out that I.pandurata is found almost exclusively in dry well-drained soils, that huge root you uncovered must be many-many years old. What an OLD Man of the Earth!
berrygirl - your photos are interesting for 2 distinct reasons as your photos are the only ones so far in this thread that show Ipomoea pandurata including
1) the sepals to have a purplish-red pigmentation on the sepals...cyano-pigmentation is often a partial defence against herbivores...
2) large ants on the sepals...Ipomoea pandurata is one of the MG's that have what is known as extra-floral nectaries(EFN) on the sepals...these type of nectaries are produced on plant parts outside of the more usual floral nectaries inside of the flower...the EFN's are most often visited by pugnacious ants and other Hymenoptera that feed on the nectar produced and have been documented to repel herbivorious insects,although this type of protection from herbivores is not completly effective,the plants equiped with EFN's are better protected that if they didn't have EFN's...hummingbirds have been photographed feeding on the EFN's of Ipomoea carnea which has the most developed EFN's of any MG species...
Emma - Robert mentioned having better success with focusing on closeups by using a manual focus here
"''The old Mavica came through for me. All it took was putting on my reading glasses and switching to to manual focus. (I'd rather look thru a viewfinder focusing...)"
You may want to try his method"...
Generally speaking,considering that the species epithet is 'pandurata',one would think that true pandurate leaves would be more common(!?)...
The following link mentions the rare Morning Glory Bee Cemolobus ipomoea a rare species of Bee that has been found only on Ipomoea pandurata and some other Convolvulaceae species
Cemolobus ipomoea Rb. was found only on Ipomoea pandurata by Robertson, on which he listed it as abundant; he speculated that it was an oligolege...collected this bee only on that plant. Any sampling effort ignoring this plant would most likely miss this bee. .Today, this species is generally considered rare (Michener et al. 1994:156). http://www.illinoiswildflowers.info/savanna/plants/ws_potato.htm
Robert - The degree of plant intra-infertility/fertility and inter-infertility/fertility in Ipomoea pandurata is directly related to the degree of genetic diversity present in the plants...Ipomoea pandurata plants that have greater diversity in the genetics have alot higher intra and inter plant fertilty...
So,Ipomoea pandurata can be a very prolific seeder or a very poor seeder based on the genetic diversity of the individual or groups of individuals in question...
The remedy for low genetic diversity is to increase(!) the genetic diversity of the pollen available by planting new plants, that originated from other areas, amongst your group ...and as long as the new plants are not too(!) closely related,the proteins displayed on the pollen will be different enough to increase the seed production...
I've been watching all the other vines for signs of blooming, but none seem to be near that point. I looked at the roadside where the county clearcut for the larger vines that were there, but I couldn't see any amongst the adventitious "weeds" that have sprung up mightily in the bare ground.
Here's a lovely bug that I think is the one responsible for the holes in the pandurata leaves.
Well, I just had to post to this thread that I searched out...I also want to find some pandurata seed and hope to remember this year. It's very prolific here in NE Oklahoma...there have to be seeding populations.
Here, it grows in more moisture retentive areas...because we're much drier than you folks out east.
I also have leptophylla seedlings...that's are now 4 years old...I'm thinking next year is the year they bloom (they're over a foot high this year).
Emma, those are beautiful... I wish I could have gotten some when I was out in the country with Bonnie. Please save me some seeds or a tuber, I will be glad to buy them, since Jackies are few and far in between. I don't worry too much about the legalities of things, I am a gardener...
Rex, From Burlingame, Kansas across from the burlingame river along a long pasture fence line.. usa they are native I.Panduratas..I found them the year before last, and then went back again this past fall to gather seeds..
Since then I have sent them out everywhere..
