Is there an Ipomoea grandiflora

A friend have bought a plant here in Sweden, it says perennial on the label and that you should cut it down, but not when?
Does anybody know about this?

Ipomoea grandiflora is an old synonym that is frequently misapplied to many different Convolvulaceae :

Ipomoea grandiflora (L.f.) Lam.
Barker, R.M. & Telford, I.R.H. (1993), Flora of Australia 50: 352
misapplied to: Ipomoea macrantha Roem. & Schult.

Green, P.S. in Wilson, A.J.G. (Ed) (1994), Flora of Australia 49: 306-307
misapplied to: Ipomoea alba L.

Johnson, R.W. (2004) Stictocardia Hallier f. (Convolvulaceae) in Queensland. Austrobaileya 6(4): 634-635, Figs 2, 3, Map 1
synonym of: Stictocardia tiliifolia (Desr.) Hallier f.

CHAH (2006), Australian Plant Census
misapplied to: Ipomoea macrantha Roem. & Schult.
synonym of: Stictocardia tiliifolia (Desr.) Hallier f.
misapplied to: Ipomoea alba L.

Also a synonym of Ipomoea latiflora...

A web search on Ipomoea grandiflora produces a wealth of nonsense...(!)

Whenever you see Ipomoea grandiflora applied...you can bet that the person doesn't know what it is that they really have (!)...

Sylvia - Please post a photo of the plant...even a photo (maybe some closeups) of the leaves and stem should aid in identification...


TTY,...

P.S. - Ipomoea ID IQ test (!)

What do you think the legitimate binomial for the flower is (?)...despite the 'confusing' vine structures (!)...look at the hair on the vine stems (!)...

Hi Ron
I have been to the plantshop today and take a photo with my mobilcamera. No so good but you can see the flower.
It´s from Patioplant and a small small twig/branch of about 20 centemetre long only for a price of 79 Skr = 10 US Dollar, expensive I think. But my friend had buy one plant.

HI Sylvia,

I agree that the photos you have posted are Ipomoea indica.
Great that you have this plant. You will love these awesome blooms.


Ron . . . OH GOODIE! A Test!

My answer to your Ipomoea ID IQ Test as I see it and after studying closely.

The Blue Morning Glory is without a doubt Ipomoea tricolor Heavenly Blue.
The Sepals are Ipomoea tricolor.
However the hairy vines are not Ipomoea tricolor.

When looking at the hairy vines in the first photo this could be hederaceae, purpurea or nil. BUT, when I look at the second photo I can see that it is definitely purpurea. The sepals on the flower bud cluster to the left of the bloom are I. purpurea. I can see the reflexed seed pods to the lower left of the upper bloom.
SO, there are actually two vines from different species intertwining.

I can see why this photo could be confusing.


Did I pass???

Emma - SHAZAAM (!)...have you been following up on the Morning Glory Megalomaniac Handbook series (!?)...seems like you have (!)...gotta keep my eye on you...El Duce gave out the vote way too easily...

Sylvia - That's one beautiful vine! Though for $10 I would probably trade seeds to get it. :-)

Ron - I would've totally blown your test. I would guess Blue Star I. tricolor. I guess I am just too shallow as I typically like growing them for their beauty and don't pay as much attention to details in the stems, sepals, etc. But I do seem to remember vines when I actually grow them. I am a hands-on learner. :-)

Becky - "I typically like growing them for their beauty and don't pay as much attention to details in the stems, sepals, etc"

I see Beauty where others might just see stems,sepals,etc...

Ron

So true, Ron! Maybe I just need a better pair of glasses! ;-)

I experience it more as a frame of mind...

There was a time when I simply looked...and that was OKay...and then the deeper I looked,the more I saw....

There was a time when I viewed all the technical names as a total BORE and I rejected them as something that only 'technical' minded people could possibly be interested in...and I thought that people who were 'too' technical were unable to experience Beauty 'properly' in what they saw...I was very wrong about that...(!)

but as I saw more I naturally wondered (!) if these parts had names (?!)...and then there I entered the 'Helen Keller' phase after realizing that all these parts did have names (!) in order to help organize the world of experience...and the names became a new language in a way almost as beautiful as what they represented...

The Plants continue to be the Annie Sullivan to my 'Helen Keller'...helping to interpret the sounds that I utter...

Beauty is in the Experience of the Experiencer and not in 'things'...


and so it goes ...

Is there an Ipomoea grandiflora...?


Depends on your reference point...


I think they are all Ipomoea grandiflora...(!)

Ron . . .
Fabulous Explanation !


Sylvia . . .
In case I missed it somewhere already mentioned.
Ipomoea indica is a PERENNIAL so it would be best if you grew yours in a container and keep moving it to a larger as needed by the plant. After your plant multiplies enough, you can experience growing it in the ground as well. Of course, it won't survive your winter temps, but it would be fun to see how quickly it will bloom for you.
Another thing is that many Ipomoea indica plants do not produce seeds and some will abundantly. Also chances are greater for vines that do not readily produce seeds to grow as many different strains together as you can. My vines DOES produce seeds occasionally but I have learned to bag the pods because when they are totally mature they will spill directly to the ground without waiting for you to collect them as you do with most Morning Glories. I'll need to figure out a way to send you some of my Blue Dawn.

Be sure to let us know how your Blue Dawn does for you.

Yucatan Mexico strain that does produce seeds.
Blooms turning to a Dark Pink at night

Hi Sylvia... they have those plants for sale in the uk for £9.99.... .... sent you dmail

Hi Everyone, thanks for answer Ipomoea indica, I had it in my mind, but could´nt rember it.
