I love this plant. After beeing in my garden for a year it is app. 10 times its size without beeing invasive. At this moment (end of may) it is covered with tons of white flowers that lasts all summer long. Although it is suggested to plant this flower in morning sun only, mine gets mostly afternoon sun and is still growing well.

I love this plant! The blooms are many, tiny and perfect! It tripled itself in my garden in less than 2 months, yet doesn't seem to be invasive. I think it's an excellent alternative to "Snow in Summer", which can be invasive.
