One of the really good Bletilla hybrids which develops very wide pleated leaves - wide for a Bletilla anyway - and tall spikes of pink flowers.  Again, tall for a Bletilla but 30" is nothing to sneeze at especially when you get more flowers than the typical species.  Easy and vigorous in Zone 6b , maybe lower.

Chinese Ground Orchid.  Hardy Orchid that does great outside here.  My mom had a big patch on the west side of her house near Hadlock which had over 50 flower stems.  Deep lavender-pink perfect orchid flowers.  Easy.  Mom's gardening doctrine is that of Benign Neglect.

This is a cultivar being exported from Holland.  The flower color is a shade darker than typical so that is good.  What isn't good is that this is an imposter.  One reference we found says the flowers should face upwards, this doesn't but if it did, it would merit clonal naming.  "Shi-ran" is simply the Japanese name for Bletilla
