The lowly Jerusalem artichoke, neither an artichoke, nor from Jerusalem, is a great native plant to grow in the northeast. It is actually

I look forward to harvesting these tasty tubers after the first frost. Right now, I am cutting off their little flower heads. Unfortuantely, they make a poor cut flower, killing themselves off by acidifying thier own water very quickly. Annika, having studied biology and begining chemistry, suggested that we find a way to neutralize the acid. We tried baking soda in the water, and it workd rather well; the flowers kept for several days. This is an easy demonstration for the kids to try--one vase (use a clear bottle or vase for best viewing) with baking soda, and one without. The water without the baking soda turns a nasty, acidic brown very quickly. The one with baking soda remains clear. If you do not stir the water after adding the baking soda, the acid forms a brown layer over the clear water. Make sure the stems are in the clear part for longest lasting blooms. The acidic water, after a few days, begins to small like a marsh--lots of decay going on in there!
We cut the flowers off so that the energy produced by the plant is stored in tubers rather than spent on flower production. We discard most of the flowers, but thanks to Annika's good idea, we now decorate the house with these lovely Jerusalem artichoke flowers!

I read these Jerusalem Artichoke postings with a shudder.
When we first moved to the farm I remade the garden beds, moving soil here and there. In the process I unfortunately unearthed and distributed some JA tubers. They sprouted everywhere, overwhelmed newly planted rasberries, and shaded and pushed out vegetable plantings.
It has taken over 10 years of digging and burning (no simple composting for these tenacious roots)and this is the first year the garden was not menaced by them.
If I had know more and kept them contained, perhaps I would have enjoyed their sunny flowers and tasty root too.;)
That said, keep posting and I will keep reading and when the next JA rises, I may find a way to incorporate it into our garden.

Hey Viv! (I know, I own you an email...bad MacBeth!) I only plant things that confound my neighbors. ;)
If you harvest them from the outside edges, and work your way in, it helps to keep them contained. Personally, I find them easier than bamboo, which I have seen invade in a horrible way. But yeah, keep them contained, and harvest vigorously (they are delicious!) and it should work out.
