Could you water plants with heavy water? What would be the effect? Would they survive/thrive?

The "semi-heavy water" section of the wikipedia entry is somewhat misleading because you can buy highly pure (99%+) heavy water. It's expensive but not ridiculously so: Aldrich will sell you a liter for $840.

Some useful information about heavy water toxicity: here, here, here, here, and here (this seems to be the original mouse paper the others site). Based on the fact that D2O inhibits microtubule polymerization at high enough concentrations I expect it would be toxic to plants at similar levels as it is to animals.

Semi-heavy water is I believe what the idiot Wikipedians are calling the hypothetical compound, DOH. Heavy water is D2O.
