color:navy'>I do not think the use of native plants should be a requirement for
a green building code, but it would be prudent to have high standards for
avoiding the use of invasives. I don’t think we need to tell people that
they shouldn’t plant tulips. It would be good to be able to distinguish
between species like Crocus vernus, which has a long track record and, as far
as I know (the situation may be different in warmer climates) is not invasive,
and species like Pennisetum alopecuroides, which has cultivars that are turning
out to be more invasive than previously reported (we have been battling cv.
hamlin at our headquarters in Pittsburgh, as I have previously reported on the
Mid-Atlantic EPPC listserve). <o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif";
color:navy'>It would be good to have a protocol for testing taxa that are
relatively new to horticulture before they are considered to be of low risk for
invasiveness. I doubt we can prevent the sale of unproven taxa, but we can
alert conscientious consumers. As individuals, people might want to cautiously
try some of the newcomers and report on their behavior, but for plantings
around green buildings, they should not be used unless as part of a testing
procedure with good safeguards, in my somewhat humble opinion.<o:p></o:p></span></p>
