Ray and all,

Thanks for the comments.  They are very helpful.  The first batch I tried=a
year ago were put in the cool greenhouse because I thought they needed th=e
temperature fluctuations.

Would Z. x 'Schwartzwalder'  be the same as Z. 'Black Forest' by any
chance?  We bought one tuber of that in May 1999 at our local garden shop
and have had those beautiful purple-black flowers for 3 summers.  My wife
loves it!  We grow it in a 10-inch clay pot in straight Promix.  It sits
bone dry under a bench in the greenhouse over winter.  Probably not hardy
here....?
