Loph,
In your third link you name the blue/white striped one as Matsukaze (which I received seeds from Sbarr in the Fall Hunt~ they were in a brown coin envelope and had a typed label with description purple,white stripes)

I also received an original packet with that same color picture and wrote down all that was in English:
Brand: Takii
Variety: Pharbitis nil Choisy (FAA670)
Description: Seiryu


My notes:
(latin name. More recently Japanese morning glories are know as Ipomoea nil. Choisy was the botanist who named it.)
Description: Seiryu (sei maybe "blue"?and ryu is dragon)


What do you make of this? Which is correct? Or are they two different ones that look so much alike?
