Viscusum is the swamp azalea. It grows near water and will withstand seasonal flooding, but not constant water.

Weston's Lemon Drop is part viscosum, but not pure R. viscosum so don't assume it will be as tolerant of moist locations as viscosum.

Pink and Sweet is NOT part viscosum, but is an arborescens hybrid. R. arborescens can withstand some seasonal moisture also.

I would plant both of them on a raised bed so they get good drainage, but not directly in the muck.

rhodyman, thank you for the info--just what I was looking for!

My main local nursery has them both listed as r. viscosum, so I guess that's why I was confused with the information I'd found when I researched them.

In another article (from Fine Gardening), it says these azaleas "thrive in damp soil in full sun", and then further on says, "Light--full shade only". It's difficult to know what's really correct, with so many sources out there, especially when a supposedly reliable one contradicts itself.
