Answer: Usually these germinate fine at about 65 degrees, so I would have expected them to germinate quickly at your warmer temperature. One possibility is that they were planted too deep and have now rotted, but that is an outside chance. Sometimes these seeds will germinate easily and sometimes not, as you have discovered. A cool stratification period may do the trick. You might try chilling them (a refrigerator is good) for about a month and then bring them back into the warmth and see if they germinate.
