Question
am interested in finding out is anyone knows of a listing of perennials that do not come true from seed.  I know that sometime columbine does not come true. What are some others and is there a website you know of that might offer a list of the plants.

Thanks

Answer
There are 2 organizations whose most vocal and active members are mainly former scientists and specialists in narrow fields of interest -- they would probably love to trade intricate opinions on this subject, or at least would know others who can.  They are the American Daffodil Society's Daffnet:

(follow instructions on the website)

and the Pacific Bulb Society:

The level of knowledge that these people have is stunning and their enthusiasm is contagious.  I love reading their threads although I can only understand half of it.  Good luck.
