jw... I put the taro on a hanging shelf off the ceiling in my garage and, exactly as you describe, my garage has windows across the top... I don''t really think the amount of sunshine matters... They are in some kind of dormancy, lose their leaves and die back almost completely... The same for the Hosta in the waterfall...
Tink... I was thinking about you when I posted these pictures, as I think you have the Rocket also... Neither of the Ligularia are bare root in the pond... The Rocket is planted in dirt next to the pond but is much more tolerant of direct sun than the round-leaved one in my filter... I moved the round-leaved one so it has wet feet in the filter and it does not wilt at all now... It is in a pot with soil... They both need beau-coup (lots of) water... but mine are close to my Savio skimmer, so when I clean it, they are the recipients of all the goop I wash off the filters... Thanks for the picture posting instructions!!! I used to know how to do it but senility slowly sets in..... In my case it might not be so slow...
