Where are blue periwinkle flowers found?

Question

Their native land? :)

Answer 1

Blue periwinkle, Vinca major, Dogbane Family/Apocynaceae is a native from southern Switzerland southward around much of the Mediterranean basin, from Portugal, Spain, southern France  to western Balkans, northeastern Turkey, western Caucasus, and across much of north Africa.

Distribution and habitat:

"Widely cultivated and has become a problem in various ecosystems, found primarily in damp and seasonally moist sites in forest, woodlands and heathlands, as well as along waterways and drainage lines (Muyt 2001). Blue periwinkle invades dry coastal vegetation, heathland and heathy woodland, lowland grassland and grassy woodland, dry sclerophyll forest and woodland, damp sclerophyll forest, riparian vegetation, and warm temperate rainforest (Carr et al 1992)."
