Mary - I think you need at least 100 to have wide selection of all the forms and colors. There is such a huge variety of daylilies!
I am serious on the 100. I have had thousands at a time, but the 100 or so I have now are really my favorites from all the years. Every year I try to add a couple ones I miss growing, or a couple new ones, but something has to go to make that happen. It is getting harder and harder to let any go. I love all of the ones I have now.
250 was also a nice number.....
