My 'Blue Ipomoea nil' from Reunion Finally Bloomed.
Only information stated was
"Originating from Africa, this is a delicious ipomoea (morning glory) with pale blue flowers having a white heart. As other annual ipomoeas it will grow fast on any prop and will bloom some two to three months after sowing. The whole plant is covered with short hairs, on the stem, leaves, and even fruits. On Reunion island it blooms during austral winter, which corresponds to short days (under 12 hours of light)."

Anyone else ever grown this?
Any idea what the name is?
