Nice Kirinmaru and Tacitaiho, Matt! I know nothing about Tacitaiho, but Kirinmaru refused to thrive for me for unknown reasons -- so I gave it away.
Most people seem to have great luck with it.
I grow primarily bean leaf varieties or "beanies" as I like to call them. Among my favorites are Kasen, Otaka no Yuki, Tsushima Ryokuhou, Kabutomaru, Tengyokuhou, Suigai and Aoshinju. Each one of these is unique in appearance and quite easy to distinguish from the others.
All of these are strong plants. Suigai and Otaka no Yuki have the longest leaves among these seven varieties. Tengyokukou and Tsushima Ryokuhou have the widest leaves of these seven. Aoshinju is the tiniest plant overall.
Kasen produces clouds of slightly smaller standard white flowers with bright yellow staminodes and quickly forms beautiful, medium green, low-mounding clumps. Kabutomaru forms magnificent towering clumps because each growth can become very tall and is clothed with leaves from top to bottom. Kabutomaru holds its leaves for a very, very long time.
Kabutomaru and Tengyokuhou both have skyward-facing flowers with short spurs. Kabutomaru produces pure white flowers with very good scent, and Tengyokuhou's flowers are white tinged with pink edges. Tengyokuhou's leaves are noticeably wide. Both are good bloomers.
Suigai has magnificent, dark green pointed leaves and produces large, very long-spurred, skyward-facing flowers which are white and tinged with pink edges.
Otaka no Yuki displays a fine yellow edge on some of its leaves and produces standard white flowers often tinged with pink. It is an exceptional bloomer, and the flowers have very good scent as well.
Tsushima Ryokuhou is very uniform and neat in appearance and produces beautiful sprays of standard white flowers. Its leaves can become quite wide as well.
Aoshinju (Blue Pearl) is an exceptionally tiny, clumping plant very similar to Kuroshinju (Black Pearl). I think Aoshinju is much easier to grow than Kuroshinju. Its small standard flowers are the same as Kuroshinju's except they are edged in pink.
