Thanks for your response. I was told they are planning to finish in September, so I don't expect this problem to go away any time soon. There is a small space on the east side of my house behind an azalea and some hollies that form a barrier between the house and the construction. It's only a few feet, but could I plant the rhizomes there pretty tightly and move them in the fall? It would mean one planted every few inches rather than every few feet. Might that work?

lnewport, I am interested in some of your Jerusalem Artichokes, (I don't need much, if you still have some. I have several heirloom veggie seeds if you are interested in them for a trade. LMK, thanks!

Be sure to check that colony in the spring, because they have very cool flowers close to the ground (and sometimes buried in the leaf litter). The plants in the attached photo were flowering around the middle of April, in south-central Arkansas.

Leah, I don't know about ginger but I would put the bluebells in the ground in shade/moist area (if you have a little out of the way of the construction area place) and dig them up when you are ready. I bought bluebell rootstock last Spring but a foot of snow arrived ahead of the rootstock. I dug through the snow put the rootstock in and then lost track of it. It came up on a barely covered rock this Spring and I quickly moved it. Not only had it multiplied on the barely covered rock but it flowered after being relocated this spring! Your rootstock is most likely dormant now as bluebells are very early risers in Spring so you really can't hurt them. Good luck!
