I am more concerned with the results. I have not been happy with the viability of Heucheras. If I did not love them so much I would have stopped buying them.
At this point I watch everyone and read the length of time they have had it in their garden, if they say, and the zone they are growing their plant. I have not purchased any new release for at least 2 years. I also, have had bad luck with Terra Nova. I always thought they were pumping them out to fast and not garden testing before release.
They are much to expensive to be used as a annual.
