(Click thumbnails for enlargement) On June 4, I posted photos of some plants in my garden that I couldn't identify.

A lot of people offered their opinion, but there wasn't consensus on what kind of plants they are. A few people asked me to post photos when the plants blossomed. Well, they did blossom, and they flowers are pretty -- some are white and some are purplish / mauve.

Now does anyone know what kind of plant it is?
