While dahlias produce anthocyanin, an element necessary for the production of the blue, to achieve a true blue color in a plant, the anthocyanin delphinidin needs six hydroxyl groups. To date, dahlias have only developed five, so the closest that breeders have come to achieving a "blue" specimen are variations of mauve, purples and lilac hues. [44]

Ina is a peculiar small depression ("crater" in IAU nomenclature) on the Moon, in Lacus Felicitatis. It is D-shaped , 2.9 km × 1.9 km wide and 64 m deep (from the deepest point of the bottom to the highest point of the rim).
The Moon is Earth's only natural satellite. It orbits at an average distance of 384,400 km (238,900 mi), about 30 times the diameter of Earth. Tidal forces between Earth and the Moon have synchronized the Moon's orbital period (lunar month) with its rotation period at 29.5 Earth days, causing the same side of the Moon to always face Earth.
Rima Ariadaeus is thought to have been formed when a section of the Moon's crust sank down between two parallel fault lines (making it a graben or fault trough). [3] Rima Ariadaeus shows no trace of associated volcanism and is thus considered to be an end member of the sequence where only pure faulting is involved i.e. a linear rille. [4]
