...chamaecyparis Limerick?
The bed is not a bog or even that wet, but it is a low point in my garden and when it rains heavily, it will flood but recede in 24-48 hrs. I have not lost anything that's planted there, in fact they do well (deciduous azalea, magnolia, TX Mtn laurel, EE, RLs, crinum). I have no experience with holly or chamae. but know that planted wisely, they should do well here. thanks for your help.

I have holly here and we have some years with lots of rain, and wet winters. As long as the soil drains fair you should do fine w it. I don't know the other plant, never heard of that so can't comment there. Hope you find the right thing!
