Hedychium greenii
Hedychium greenii, native to Bhutan and Arunachal Pradesh, India has long been one of our favorite gingers. As best we can determine, all of the material in cultivation is a single clone collected in Bhutan and distributed by its namesake, Mr. Green. For us, Hedychium greenii has survived since 2007 including one winter at 9 degrees F. The 3′ tall stalks, that emerge for us in late June, are adorned with dark olive green, red-backed leaves. The stalks are topped, starting in mid-July and lasting until fall, with orange-red terminal flowers. Since Hedychium greenii is sterile, it has learned to reproduce by plantlets that form on the old flower stalks.
