Chris asked, >This discussion reminds me of a question I have had about these >species. I read that T. peduncularis and to a lesser degree T. >hyacinthina are moisture-loving. Do they nevertheless require dry >dormancy in the heat of summer? Regards, Chris No, both these species tolerate summer water as long as they are in a well-drained site. However, they also tolerate dry dormancy. I have grown both in both kinds of positions for many years. Jane McGary Portland, Oregon, USA
