I saw these flowers in different colors. There are white  muscari. And blue terry. I love this plant - for its modest beauty and  unpretentiousness. Even after the harsh winters, when even daffodils  grow cold, the muscari is slowly recovering. This plant is good for  blooms in the air of your house. Muskarikov there is such a variety, that probably one can only plant  flower beds! And white, and yellow, and pink, and blue, and purple, and  terry ... All and not enumerate! 

how else can you call these flowers

Also these flowers can be called: as I already said - muscari, or mouse hyacinth, or viper onion (the family is lily).

Another tender plant Stellaria holostea. These flowers attract me thanks to their petals. Petals as if divided  into two parts, and this is similar to a star. The flowers of this  plant are painted in white tones, they are rather small.
