WHITE AQUILEGIA, COLUMBINE, OR GRANNY'S BONNETS

I like to have white flowers in my garden for two reasons: they look fresh and pretty, and they show up at dusk when all other colours have faded to grey.  A couple of years ago I planted a couple of white aquilegias but they didn't have much by way of flower.  In fact, I think one died.   Someone mentioned that they, white aquilegias, don't seem to do as well as coloured ones and I didn't expect to see anything at all this year but I have been pleasantly surprised.  This is Aquilegia Biedermeier which is in my south facing border although it is in partial shade.  Can you possibly get more flowers on one small plant than this?  I must have done something right.
