There's so little activity here I'm not holding much hope for an answer but here goes.

In a far corner of my backyard there's a low spot where adjoining yards that have been 're-graded' drain into ours. We can't regrade so in the spring with the snow melt or when we have very heavy rains in summer, this area will have standing water. It generally doesn't last long but it is a factor in planting. My giant hostas love it there. Even the 'ditch lilies' that were there when we moved in almost 20 years ago thrive although I wish they wouldn't!

I have other hydrangea varieties and know they need lots of water, so will Annabelles be ok with wet feet in the spring?
