I took the above picture in Geneva in the summer of 2014.
Ipomoea is the largest genus in the flowering plant family Convolvulaceae, with over 500 species. The Wikipedia informs us that it is a large and diverse group with common names including morning glory, bindweed, moonflower, etc.
Ipomea indica is a perennial vine native to tropical habitats. Blue morning glory is one of its favored common names.
Most morning glory flowers unravel into full bloom in the early morning.
The flowers usually start to fade a few hours before their gossamer petals start showing visible curling in on themselves. This would draw my attention immensely as a child. The flowers prefer full sun exposure throughout the day. Some morning glories, however, are night-blooming flowers.
The climate of Geneva, where I visited my elder daughter who moved there in the spring of 2014 is temperate and oceanic indicating that the winters are mild, usually with light frosts at night and thawing conditions during the day. Summers are pleasantly warm. Precipitation is sufficient and, relatively well-distributed throughout the year, although autumn is slightly wetter than the other seasons. This being the case, at the botanical garden of Geneva as well as the city I came across morning glory and many other warm climate plants.
