Positive Reynardine On Jan 27, 2013, Reynardine from Lake Helen, FL wrote:

I have had Cynthia in Lubbock, Texas, and I have had her in Kendall, Florida. That is quite a wide range of climate, humidity, and soil texture. Both areas tend to alkaline soil; because I can't find her for sale anywhere now, I haven't been able to test her out in the slightly acidic soil we have here. She is stalwart, fragrant, unfading, and stands the harshest sun; she is a rose of roses, matched in roseness only by Ena Harkness, who is, however, more delicate in constitution.
