That sounds like an honest description of many varieties.
Hi Loretta,
Yes, definitely honest. The purpose of my post though was because I am not clear on some info I have recently "heard".
I have just read that the shape or form of zinnia seeds could potentially give us a clue as to whether they will be singles or doubles.
I have also read recently that single or double zinnias could be determined when they grow depending on different environments or using different methods. I have heard of germination rates being affected and I can see that but I am not clear on these other two.
