Ipomea indica

may be planted, may be a volunteer

was the leaf soft and downy???

considered a pest in florida and even as far as in Australia

https://weeds.brisbane.qld.gov.au/weeds/morning-glory

this Australian site describes the plant to a T so people can id it and eradicate it...

Quote" A showy twining climber or scrambling plant with hairy stems.

 Its alternately arranged leaves (5-18 cm long and 3.5-16 cm wide) are either heart-shaped or three-lobed.

 Its large funnel-shaped flowers (5-10 cm long and 7-10 cm across) are blue or bluish-purple in colour

 with pale pinkish centres. These flowers have long and narrow sepals (14-22 mm long) and are borne

in clusters of two to twelve in the leaf forks.

This species does not produce viable seed in Australia, and fruiting capsules are rarely seen here." end quote

and yet they consider this weedy? go figure.

All I can do is guess ....because there is no tube , no calyx . And my guess is , Ipomoea purpurea . Neither Ipomoea indica nor Ipomoea parasitica nor Ipomoea nil . I have not seen Ipomoea indica with leaf margin entire .

Rakesh,

leaves can be entire or lobed I think

why do I like weed eradication sites?

because often the leaf is what one needs to know to pull out the

noxious plant

see page 4 of this weed  site

First and foremost , without calyx and tube , ID will always remain guesswork . 

In a park , as ornamental , Ipomoea purpurea is the common choice . 

As for the leaf , in the species I see in Surat , those with trilobed leaf , seedling further develops entire leaf earlier in its life , by the time flowering begins new leaves become trilobed . This is the story of I. marginata , I. triloba , I. nil . Wherever I saw I. indica it was already flowering , all the leaves trilobed.....never found a leaf with entire margin......in fact it is recognised by relatively larger flower and smaller leaf as opposed to I. nil with larger leaf and smaller flower . 

Again I say , it is calyx , tube , corolla combo we need to get to an ID .

Here is one more pointer . In I. indica tube is pink , and for this reason throat looks red in a frontal view photograph . In I. nil and I. purpurea , tube is white and throat looks white . In I. parasitica throat is yellow because of the yellowish tube .

Rakesh Ji,

Agreed.

Infact the flower and leaves match completely with one I have posted from Atlanta.

That was identified by Ron Kushner Ji, expert on Convolvulaceae.
