I agree Ann it is one of my favorites too. I just purchased it last summer and it was growing like a weed. I like it because it is different and adds to the shade garden as another texture .
I was surprised to find it so cheap.
My shade garden does not get any sun not even an hour. So it did not get that white color until Aug. Also because of the deep shade my blues stay blue, the white color makes the Heucheras color and the blues stand out. I love, love, love the white. I really love the white it adds to the shade. Did I say I love the white.
