A Flower To Auroville Mother-76

Periwinkle(Vinca, Catharanthus roseus)
Tiny Periwinkle(Tiny Vinca, Catharanthus pusillus)

Not minor nor major, only nearer
Vinca different of Periwinkle
At my door side and everywhere
Shrubby small all-time sparkle
Of contortion incoordinate fate
O'but toxigenic yet therapeutic
Of vincine alkaloids beating fate
Colourful of varieties many
Perennial Roseus wide found
Lance-leafy Vinca annual tiny
Penta-petaled flora all lauded
