Eomecon chionantha invasiveness

[Ruth Bierhoff]

Hello all,
I rarely communicate with  the group, but am in the midst of ordering
plants for fall and a question arises as to the invasiveness of Eomecon
chionantha in Zone 6a, Westchester County, New York, USA.

This would be planted in a woods garden area on a slope facing North,
where my Trillium appear about 2 weeks later than others in this Zone.
Therefore, I think the area may be more like Zone 5.

Information on the web varies apparently according to the area of the
writer, so now I'd appreciate some definitve thoughts for my area before
I plunge into disaster.

Many thanks,
Ruth Bierhoff, Zone 6a, Pleasantville, New York, USA, minimum
temperature -10 F (haven't seen that for a while)
