There's something cheering about seeing the occasional early flower that's decided to raise its head rather too soon- like this Periwinkle I saw on Sunday.
 This is the Greater Periwinkle (Vinca major) and it is more usual to see it flowering on the cusp of late winter/early spring. So too the Lesser Periwinkle (Vinca minor) which has similar starry flowers. Both do well in shady surroundings but V. minor has a low growing, spreading habit whereas V. major is a taller, shrubbier plant.
