This is a pretty serious Bletilla and it would have to be with a moniker like 'Big Bob'.  It was a dream of mine to have a nickname like that but we'll delve into my psyche and childhood later.  Tall flower stems in ideal situations reaching 3' in height and bearing 15-20 pinkish unquestionably I'm-an-orchid flowers.

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.
