Diana, your beautiful Blue Billows hydrangea looks as happy as if it had never been moved. It's the outer cornerstone of my reworked front landscape bed (between the front door and the outer corner of the house). I'd been wondering what to put there, and it's perfect! Thank y ou!
The water celery does "escape" from a water garden pot from time to time and grows quite happily nearby... may get a bit more water than the rest of the garden areas from when I top off the pot (I stick the hose in, then get distracted, and the pot overflows). I have a really big clump that I've weeded out of the lotus pots, just threw it on the ground, and it's still showing green 2 weeks later.
