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!

Would love to help you and those BS butterflies. I have ginger to trade if you would like to trade for your daffs. Sending you a email. Good luck

Wild ginger and edible ginger are different. Not that you couldn't try eating it. fyi--there are many types of ginger. including the wild yellow and white and shampoo which grow wild in Hawaii. There is also a type that they pickle the flower heads that grow out of the ground from the rhizome. I once had it, but I lost it unfortunately. The flowers on commercial ginger are not at all like those of the wild ones. There is also a cultivated 'blue' ginger, which is also grown for its flowers not as food.
