Tall Morning Glory 'Aomurasakizyouhantenshibori'

Also called simply Shibori (Dappled or Flaked), Emma's Gift, and Carnevale di Venezia.
This fancy heirloom strain of Ipomoea purp...Read Moreurea was named Carnevale di Venezia not just as a marketing name but also because it's believed to have historical connection to Venice.
An older relative of mine found seeds of this variety for sale in Venice while she was there on European vacation. Because it was unlike any other morning glory she had ever seen, my relative asked about the plant's history. The Venetian seed vendor said the variety had been grown in Venice a very long time- at least since the Crusades- and that where it came from before that is uncertain.

Sorry to be a stickler for proper plant naming, however- Pretty please do not confuse this plant with 'Tye Dye Blue' or 'Tie Dye Blue'...Those are incorrect names for this plant.
The actual 'Tie Dye Blue' JMG is a whole different striped MG from Japan- Ipomoea nil. It has larger flowers with a different flower shape, and overall looks quite different.

According to my Japanese translator:

This name is constructed with these 3 words.
Aomurasaki zyouhanten shibori...Read Morer />
Not zyouhaten, zyouhanten is correct.
Not sibori, shibori is correct.

"ao" is blue,
"murasaki" is purple,
so, "aomurasaki" means bluish-purple.

"zyou" originated from branch, it means stripe for MG's.

"hanten" means a spot,
so, "zyouhanten" means Striped and Spotted.

"shibori" means dappled

"aomurasaki zyouhanten shibori" is just explained what they look like:

Bluish-purple, Striped, Spotted, and Dappled.
